Which Type of Pump Is Best: A Comprehensive Guide to Selecting the Right Pump

Which Type of Pump Is Best: Navigating the Choices for Optimal Performance

The nagging hum from the basement, the persistent drip that won't stop, or the need to move fluid from point A to point B – these are all scenarios where the humble pump becomes an indispensable hero. I remember wrestling with a leaky sump pump system in my old house. It seemed like no matter what I did, water kept finding its way in, and the pump I had just wasn't up to the task. This experience, frustrating as it was, really hammered home the fact that not all pumps are created equal. Choosing the *best* type of pump isn't a one-size-fits-all answer; it's a deeply personal decision that hinges entirely on what you need it to do. Let's dive into the nitty-gritty of pump selection, ensuring you'll never have to face a flooded basement with the wrong tool for the job again.

The Ultimate Answer: Which Type of Pump Is Best?

The type of pump that is best is the one specifically designed for your application, considering factors like fluid type, required flow rate, head pressure, power source, and budget. There isn't a single "best" pump for all situations. A submersible pump might be ideal for a well, while a centrifugal pump excels in many industrial and domestic water transfer tasks. For thick, viscous fluids, a positive displacement pump is often the superior choice. Understanding these nuances is the key to making the right selection.

Understanding the Fundamentals: Why Pump Selection Matters So Much

It might sound straightforward – you need to move liquid. But the reality of pumping is far more complex. The fluid itself, the distance it needs to travel, the height it needs to be lifted, and even the ambient conditions all play a critical role. Using the wrong pump can lead to a cascade of problems: inefficient operation, premature wear and tear, energy waste, and ultimately, system failure. This isn't just about inconvenience; in industrial settings, it can mean costly downtime and safety hazards. For homeowners, it can mean property damage and expensive repairs. My sump pump saga taught me that the initial cost of a pump is often far less than the long-term cost of a poor choice.

Categorizing Pumps: A Bird's-Eye View

Broadly speaking, pumps can be categorized into two main types: **dynamic pumps** and **positive displacement pumps**. This fundamental distinction helps us understand their operating principles and where they shine.

Dynamic Pumps: Harnessing Momentum

Dynamic pumps, also known as kinetic pumps, work by imparting kinetic energy to the fluid. They rely on a rotating component, typically an impeller, to accelerate the fluid and then convert this velocity into pressure. These pumps are generally well-suited for moving large volumes of low-viscosity fluids. They are known for their smooth, continuous flow and relatively simple construction.

Centrifugal Pumps: These are the workhorses of the pump world. They use a rotating impeller to create centrifugal force, pushing the fluid outwards and into the discharge pipe. Their design is versatile, and they come in many variations, from small utility pumps to massive industrial units. They are excellent for water, light oils, and other non-viscous liquids. Axial Flow Pumps: Instead of pushing fluid radially outwards like centrifugal pumps, axial flow pumps move fluid parallel to the shaft. Think of a propeller in a pipe. These are ideal for high-volume, low-head applications, such as moving large quantities of water in drainage or irrigation systems. Mixed Flow Pumps: As the name suggests, these combine features of both centrifugal and axial flow pumps. They offer a balance between flow rate and head pressure, making them versatile for a range of applications. Positive Displacement Pumps: Capturing and Pushing

Positive displacement pumps work by trapping a fixed volume of fluid and then forcing it through the discharge. They deliver a consistent volume of fluid per revolution or stroke, regardless of the discharge pressure (within the pump's limits). This makes them ideal for handling viscous fluids, high-pressure applications, and situations where precise flow control is essential.

Reciprocating Pumps: These use a piston or diaphragm that moves back and forth within a cylinder to displace fluid. They can generate very high pressures. Examples include: Piston Pumps: Common in high-pressure cleaning and hydraulic systems. Diaphragm Pumps: Often used for handling corrosive or abrasive fluids, as the diaphragm acts as a barrier between the fluid and the pump's mechanical parts. Rotary Pumps: These use rotating elements to trap and move fluid. They are known for their smooth, pulsation-free flow. Examples include: Gear Pumps: Simple and robust, with intermeshing gears trapping fluid between them. Excellent for oils and hydraulic fluids. Lobe Pumps: Similar to gear pumps but with lobes instead of gears, allowing for handling of larger solids or more delicate materials. Screw Pumps: Use one or more rotating screws to move fluid axially. They can handle a wide range of viscosities and are known for their quiet operation. Vane Pumps: Feature sliding vanes within a rotor that trap fluid as the rotor turns. Peristaltic Pumps: These are unique in that the fluid is contained within a flexible tube that is squeezed by rollers. This means the fluid never comes into contact with the pump mechanism, making them ideal for sterile applications or hazardous chemicals.

Key Factors in Pump Selection: The Checklist for Success

Now that we have a basic understanding of pump types, let's delve into the critical factors you absolutely *must* consider when deciding which type of pump is best for your needs.

1. Fluid Characteristics: What Are You Pumping?

This is arguably the most crucial starting point. The nature of the fluid dictates much of the pump selection process.

Viscosity: Is the fluid thin like water, or thick like molasses? High viscosity fluids require positive displacement pumps because centrifugal pumps lose efficiency rapidly with increasing viscosity. Think about pumping syrup versus pumping water – you'll need very different pumps. Temperature: High or low temperatures can affect fluid viscosity and pump materials. Special seals and materials might be necessary for extreme temperatures. Corrosiveness/Abrasiveness: Is the fluid acidic, alkaline, or does it contain solid particles? Corrosive fluids will require pumps made from resistant materials like stainless steel, titanium, or specialized plastics. Abrasive fluids will wear down pump components quickly, necessitating pumps with hardened parts or designs that minimize wear, such as diaphragm or peristaltic pumps. Solids Content: If the fluid contains solids (slurry, pulp, debris), you'll need a pump designed to handle them without clogging. Grinder pumps, vortex impeller pumps, or pumps with larger internal clearances are often suitable. Volatility: Highly volatile liquids (low flash point) may require special considerations to prevent cavitation or vapor lock. 2. Performance Requirements: How Much, How Far, How High?

Once you know what you're pumping, you need to define how you want it pumped.

Flow Rate (GPM or L/min): This is the volume of fluid the pump needs to move per unit of time. Is it a trickle or a deluge? Head Pressure (PSI or Feet of Head): This is the total resistance the pump must overcome. It includes: Static Head: The vertical distance the fluid needs to be lifted. Friction Head: The pressure loss due to friction in the pipes, fittings, and valves. Velocity Head: The energy required to accelerate the fluid. Pressure Head: If the discharge point is under pressure. Understanding total head is vital for selecting a pump that can deliver the required pressure. System Curve: This is a graphical representation of the system's resistance to flow at different flow rates. Matching the pump's performance curve to the system curve is crucial for optimal operation. A pump that's too large for the system will waste energy and potentially damage itself; one that's too small will simply not deliver the required flow. 3. Power Source: What's Available?

The type of power available can significantly influence your pump choice.

Electric Motors: The most common power source for pumps. Consider single-phase (for residential) versus three-phase (for industrial). Internal Combustion Engines (Gasoline/Diesel): Useful for remote locations or where electricity is unavailable. Hydraulic Power: Often used in heavy-duty mobile equipment. Manual Power: For very small-scale or emergency use (e.g., hand pumps). 4. Installation and Environment: Where Will It Go?

The location and operational environment are key considerations.

Submersible vs. Above-Ground: Will the pump be submerged in the fluid (e.g., sump pump, well pump) or located outside the fluid? Submersible pumps are often more efficient for lifting from depth but can be harder to access for maintenance. Space Constraints: Is there limited space for the pump and its associated piping? Environmental Conditions: Will the pump be exposed to extreme temperatures, moisture, dust, or hazardous atmospheres? Explosion-proof motors or specialized enclosures might be necessary. Noise Levels: Some applications require quiet operation. 5. Cost and Maintenance: Budget and Longevity

The initial purchase price is only part of the equation. Consider the total cost of ownership.

Initial Cost: The price of the pump itself. Operating Cost: Primarily energy consumption. More efficient pumps will save money over time. Maintenance Cost: Ease of repair, availability of parts, and frequency of maintenance. Some pump types require more specialized maintenance than others. Lifespan: How long is the pump expected to last under the given operating conditions?

Deep Dive into Specific Pump Types and Their Ideal Applications

Let's get more granular and explore some of the most common pump types and where they truly excel. This will help you pinpoint exactly which type of pump is best for your situation.

1. Centrifugal Pumps: The All-Arounders

As mentioned, centrifugal pumps are incredibly common. Their versatility is their strength.

How they work: A spinning impeller draws fluid into its center and forces it outwards due to centrifugal force. The volute casing then collects the fluid and directs it to the discharge outlet, converting velocity into pressure. Best for: Low-viscosity fluids like water, light oils, solvents. Moving large volumes of fluid. Applications where a smooth, continuous flow is desired. Residential water supply, irrigation, general industrial transfer, HVAC systems, pool pumps. When to avoid: Highly viscous fluids (efficiency drops dramatically). Fluids with significant solids that could clog the impeller. Applications requiring extremely precise flow control or very high pressures without significant flow. Variations: End-Suction Pumps: The most common type, with the suction nozzle at one end and the discharge at the top. In-Line Pumps: Designed to be installed directly into the pipeline, saving space. Multistage Pumps: Feature multiple impellers in series to achieve very high head pressures. Self-Priming Pumps: Designed to handle air in the suction line, making them easier to start. Submersible Centrifugal Pumps: Motor and pump are housed in a watertight enclosure and submerged in the fluid. Ideal for wells and sumps. 2. Submersible Sump Pumps: Keeping Basements Dry

These are a specific application of submersible centrifugal pumps and are crucial for homeowners.

How they work: Placed at the bottom of a sump pit, they activate when water reaches a certain level, pumping it out and away from the foundation. Best for: Removing groundwater and preventing basement flooding. Draining flooded areas. Key Considerations: Horsepower: Affects pumping capacity. Higher HP for deeper pits or higher head. Discharge Size: Needs to match your discharge pipe. Float Switch Type: Vertical float switches are common and reliable; tethered floats can get snagged. Material: Cast iron or thermoplastic for durability. Backup Systems: Consider a battery backup for power outages. My Experience: I learned the hard way that a cheap, undersized sump pump is a false economy. When the power went out during a heavy rainstorm, my old pump failed, and the basement flooded. Upgrading to a more powerful cast-iron model with a reliable float switch made all the difference. 3. Well Pumps: Bringing Water from Below

These are essential for homes and properties relying on well water.

Types: Submersible Well Pumps: The most common type for deep wells. They are placed below the water level and push water upwards. They are generally more efficient and quieter than jet pumps. Jet Pumps: Typically located above ground, they use a venturi system to create suction. They are less efficient for deep wells but can be easier to service. They come in shallow-well (single-pipe) and deep-well (two-pipe) configurations. Hand Pumps: A manual option for shallow wells, useful during power outages. Best for: Providing potable water for homes, farms, and other uses from underground wells. Key Considerations: Well Depth: Determines the type and horsepower needed. Water Level: Static water level and drawdown during pumping. Flow Rate and Pressure: Needs to meet household demand. Pump Material: Stainless steel is often preferred for longevity and to prevent rust. 4. Diaphragm Pumps: Handling the Tough Stuff

These positive displacement pumps are known for their ability to handle challenging fluids.

How they work: A flexible diaphragm is moved back and forth by a mechanical linkage or compressed air, creating a pumping action. Check valves control the flow in and out. Best for: Corrosive, abrasive, or shear-sensitive fluids. Slurries and mud. Applications where a pulsating flow is acceptable or even desirable. Chemical transfer, wastewater treatment, food processing. Advantages: No rotating seals in contact with the fluid, reducing leakage risk. Can run dry without damage (some models). Good for self-priming. Disadvantages: Pulsating flow requires dampeners for smoother discharge. Lower flow rates compared to many centrifugal pumps. Diaphragm wear can be a maintenance concern over time. 5. Gear Pumps: Robust and Reliable for Oils

A staple in many industrial and automotive applications.

How they work: Two or more meshing gears rotate, trapping fluid between the gear teeth and the pump casing, carrying it from the inlet to the outlet. Best for: Lubricating oils, hydraulic fluids, fuels. Applications requiring consistent flow and moderate pressure. Transferring viscous, non-abrasive fluids. Advantages: Simple, compact, and robust design. Good volumetric efficiency. Can handle moderate temperatures. Disadvantages: Not suitable for abrasive fluids, as they cause rapid wear. Can be noisy. Not ideal for very low viscosity fluids where leakage past the gears (slip) becomes significant. 6. Peristaltic Pumps: The Clean Choice

These are unique and incredibly useful for specific applications.

How they work: Rollers compress a flexible tube, squeezing the fluid along the tube and creating suction ahead of the roller. Best for: Sterile applications (medical, pharmaceutical, food and beverage). Hazardous or corrosive chemicals, where containment is paramount. Dosing and metering small, precise volumes. Handling shear-sensitive fluids. Advantages: Fluid is completely contained within the tube; no contamination. No seals or valves in contact with the fluid. Can run dry indefinitely. Self-priming. Disadvantages: Tube wear is the primary maintenance issue; tubes need regular replacement. Lower flow rates and pressures compared to other pump types. Higher cost per gallon pumped for large volumes. 7. Screw Pumps: Smooth and Quiet Movers

Often overlooked, screw pumps offer distinct advantages.

How they work: One or more rotating screws move fluid axially from the inlet to the outlet. Best for: Viscous fluids, including sludge and heavy oils. Applications requiring low shear and smooth, pulsation-free flow. Wastewater treatment, oil and gas industries, food processing. Advantages: Very low shear, ideal for sensitive materials. Quiet operation. Can handle a wide range of viscosities. Good efficiency. Disadvantages: Can be physically larger and heavier than other pump types for the same flow rate. More complex design compared to gear pumps. 8. Air-Operated Double Diaphragm (AODD) Pumps: Versatile Workhorses

These are incredibly popular in industrial settings for their flexibility.

How they work: Two diaphragms are connected by a shaft. Compressed air alternately drives one diaphragm while the other fills. Check valves control the fluid flow. Best for: Transferring a wide variety of chemicals, solvents, paints, and slurries. Explosive environments (no electrical ignition source). Portable or temporary pumping applications. Wastewater, paint and coating industries, chemical processing. Advantages: Can run dry without damage. Self-priming. Variable flow and pressure by adjusting air supply. Can handle solids. Safe in hazardous locations. Disadvantages: Requires a compressed air supply, which can be costly to generate and maintain. Pulsating flow. Lower energy efficiency compared to electric pumps.

Putting It All Together: A Decision-Making Framework

Let's create a structured approach to help you answer, "Which type of pump is best?" for your specific needs.

Step 1: Define Your Application

Be as specific as possible. Are you pumping clean water from a well, moving thick sludge in a treatment plant, or dosing chemicals in a laboratory?

Step 2: Characterize the Fluid

Gather all relevant details: viscosity, temperature, presence of solids, corrosiveness, etc.

Step 3: Determine Performance Requirements

Calculate your required flow rate and total head pressure. If possible, develop a system curve.

Step 4: Evaluate Power Availability and Constraints

What power sources are readily available? Are there any limitations on power consumption?

Step 5: Assess Environmental and Installation Factors

Consider space, noise, temperature, moisture, and safety regulations.

Step 6: Research Potential Pump Types

Based on the above, narrow down the types of pumps that are suitable. For instance:

Application Type Likely Fluid Key Requirements Recommended Pump Types (Initial List) Home Water Supply (Shallow Well) Clean Water Moderate flow, moderate pressure, reliability Jet Pump (Shallow Well), Small Submersible Centrifugal Home Water Supply (Deep Well) Clean Water Moderate flow, high pressure, reliability Submersible Well Pump (multi-stage) Basement Flood Prevention Dirty Water, some debris High flow when needed, reliability, automatic operation Submersible Sump Pump (cast iron or heavy-duty plastic) Industrial Chemical Transfer Corrosive, potentially volatile Chemical resistance, containment, precise flow (sometimes) Diaphragm Pump (material specific), Peristaltic Pump (for smaller, precise dosing), Magnetic Drive Centrifugal Oil Transfer Lubricating Oil Moderate viscosity, consistent flow Gear Pump, Screw Pump Slurry/Mud Transfer Water with solids Solids handling capability, abrasion resistance Diaphragm Pump, Slurry Pump (specialized centrifugal with large impeller), Screw Pump Dosing Chemicals Various chemicals Precision, low flow rate, repeatability Peristaltic Pump, Metering Diaphragm Pump Step 7: Consult Pump Performance Curves

Once you've identified potential pump types, obtain their performance curves from manufacturers. Overlay your system curve onto the pump curve to ensure they intersect at your desired operating point.

Step 8: Consider Manufacturer Support and Parts Availability

Choose reputable manufacturers with good customer support and readily available spare parts.

Step 9: Factor in Total Cost of Ownership

Don't just look at the upfront price. Energy efficiency, maintenance, and expected lifespan are critical for long-term savings.

Common Pitfalls to Avoid When Choosing a Pump

Even with careful consideration, mistakes can happen. Here are some common traps to sidestep:

"One Size Fits All" Mentality: Applying the same pump type to vastly different applications. Ignoring Viscosity: Using a centrifugal pump for a very viscous fluid and expecting good performance. Undersizing or Oversizing: Choosing a pump that can't meet the flow/head requirements or is excessively overpowered. Neglecting System Head: Underestimating the friction losses and static lift involved. Ignoring Fluid Properties: Using a pump with materials not compatible with the fluid being pumped. Failing to Plan for Maintenance: Selecting a pump that is difficult to access or maintain. Overlooking Power Requirements: Choosing a pump that draws more power than the available supply can provide. Believing the Cheapest Option is Best: Often, the lowest upfront cost leads to higher long-term expenses due to inefficiency and frequent repairs.

Frequently Asked Questions About Pump Selection

Q: How do I know if I need a submersible pump or an above-ground pump?

The primary determinant is the depth of the fluid source and the vertical distance you need to lift it. For deep sources like wells or sumps where the pump can be placed directly in the fluid, a submersible pump is generally more efficient and effective. They push the fluid upwards, which is more energy-efficient than pulling it upwards (as with jet pumps). Above-ground pumps are typically used when the fluid source is shallow, or when ease of maintenance is a top priority, and the pump can be placed close to the fluid source.

Consider the fluid itself. If it's something you want to keep the pump motor away from, like certain chemicals or very hot liquids, an above-ground pump with appropriate seals and piping might be better. Conversely, for clean water from a deep well, a submersible pump is almost always the superior choice. You'll need to know the static water level in your well and how much the water level drops (drawdown) when the pump is running to select the correct submersible pump and ensure it remains submerged.

Q: Why are centrifugal pumps so popular, and when might they not be the best choice?

Centrifugal pumps are incredibly popular due to their simplicity, relatively low cost, robustness, and ability to handle large volumes of low-viscosity fluids with a smooth, continuous flow. They are the go-to for many water transfer applications, from residential water systems and swimming pools to industrial cooling and general liquid transfer. Their design is straightforward, with fewer moving parts than some positive displacement pumps, which can translate to easier maintenance in some cases.

However, their suitability diminishes significantly with increasing fluid viscosity. As the fluid gets thicker, the efficiency of a centrifugal pump drops dramatically. They also struggle with very precise flow control or high-pressure applications without significant flow. If you need to pump something like thick oil, honey, or a heavy slurry, a centrifugal pump will likely be inefficient, may not produce enough pressure, or could even stall. In such cases, a positive displacement pump (like a gear, screw, or diaphragm pump) would be a much better choice.

Q: What's the difference between a piston pump and a diaphragm pump, and when should I use each?

Both piston and diaphragm pumps are types of reciprocating positive displacement pumps, meaning they use a back-and-forth motion to move fluid. The key difference lies in how the displacement is achieved and how the fluid is sealed.

A **piston pump** uses a piston moving within a cylinder. The piston forms a seal against the cylinder walls (often with rings or packing). This design is excellent for generating very high pressures and is commonly found in applications like hydraulic systems, high-pressure cleaning, and metering pumps where precise delivery is critical. However, the seals can be subject to wear, and the direct contact between the piston and cylinder can be an issue with abrasive or corrosive fluids.

A **diaphragm pump**, on the other hand, uses a flexible diaphragm that moves back and forth. This diaphragm separates the fluid being pumped from the pump's mechanical components. This makes diaphragm pumps ideal for handling corrosive, abrasive, or shear-sensitive fluids because the fluid only contacts the diaphragm and the check valves. They can also be designed to run dry without damage. While they can generate good pressures, they typically have lower flow rates and can have a more pulsating output compared to piston pumps. Their use is prevalent in chemical processing, wastewater, and food processing.

Q: How do I calculate the total head pressure I need my pump to overcome?

Calculating total head is a critical step in pump selection, as it directly impacts the pump's performance and efficiency. Total head (Htotal) is the sum of several components:

Htotal = Hstatic + Hfriction + Hvelocity + Hpressure

Let's break these down:

Static Head (Hstatic): This is the simplest component and represents the vertical distance from the surface of the fluid at the source to the surface of the fluid at the discharge point. If you're pumping from a tank and discharging to another tank, it's the difference in the liquid levels. If you're drawing from a well, it's the vertical distance from the pump (when submerged) to the point of discharge. Friction Head (Hfriction): This accounts for the energy lost due to friction as the fluid flows through pipes, fittings (elbows, tees), and valves. The longer the pipe run, the smaller the pipe diameter, the rougher the pipe interior, and the higher the flow rate, the greater the friction loss. You'll typically use friction loss charts or online calculators, which are based on factors like pipe material, diameter, length, and flow rate, to determine this value. Velocity Head (Hvelocity): This represents the kinetic energy of the fluid. It's often a relatively small component in many low-velocity systems but can become more significant in high-velocity applications. It's calculated based on the fluid's velocity and gravity. Pressure Head (Hpressure): If the discharge point is under pressure (e.g., discharging into a pressurized vessel or a system with back pressure), you need to account for this. This is usually expressed in pressure units (like psi) and then converted to head (e.g., 1 psi ≈ 2.31 feet of head for water).

For many common domestic applications like water supply, the static head and friction head are the most significant contributors. In industrial settings, pressure head can also be a major factor. It's crucial to be as accurate as possible in your calculations to avoid selecting an underperforming or over-spec'd pump.

Q: What are the advantages of using a magnetic drive pump?

Magnetic drive pumps, often a type of centrifugal pump, utilize a magnetic coupling to transmit torque from the motor to the impeller. The motor drives an outer magnet assembly, which magnetically couples to an inner magnet assembly attached to the impeller shaft. This design completely seals the pumping chamber from the outside environment, eliminating the need for a traditional shaft seal.

The primary advantage is **leak-free operation**. Because there are no dynamic seals (like mechanical seals or packing), the risk of leakage is virtually eliminated. This makes them ideal for pumping hazardous, corrosive, toxic, or expensive fluids where any loss could have significant safety or economic consequences. They are frequently used in the chemical, pharmaceutical, and semiconductor industries. Additionally, the absence of wear-prone seals can lead to reduced maintenance and longer service life in certain applications.

However, magnetic drive pumps do have limitations. They are generally more expensive upfront than pumps with mechanical seals. The magnetic coupling has a torque limit, meaning they cannot be used in applications where extreme torque is required or where the pump might stall under high load. They can also be susceptible to damage from debris in the fluid, which could jam the magnets. Finally, the efficiency can be slightly lower than a comparable sealed pump due to energy losses in the magnetic coupling.

Q: What is a "positive displacement" pump, and why is it different from a "centrifugal" pump?

The core difference lies in their fundamental operating principles and how they deliver fluid. A **centrifugal pump** is a type of *dynamic* pump. It uses a rotating impeller to impart kinetic energy (velocity) to the fluid. This velocity is then converted into pressure as the fluid moves through the pump casing. The flow rate of a centrifugal pump varies significantly with the discharge pressure – as the pressure increases, the flow rate decreases, following a specific performance curve.

A **positive displacement (PD) pump**, on the other hand, traps a fixed volume of fluid in a cavity and then mechanically forces that volume out of the discharge. Think of it like squeezing a balloon – you trap a certain amount of air and then push it out. This means that, ideally, a PD pump delivers a nearly constant flow rate regardless of the discharge pressure (up to the pump's structural or power limits). If the discharge line is blocked, a PD pump will continue to try and force fluid, leading to a rapid pressure build-up, which can be dangerous if the system isn't protected by a relief valve.

This fundamental difference makes PD pumps excellent for applications requiring precise flow control, high pressures, or the transfer of viscous fluids. Centrifugal pumps are better suited for high-volume, low-viscosity applications where precise flow control isn't as critical.

To summarize the key distinctions:

Centrifugal: Flow varies with pressure; good for low viscosity, high volume; uses kinetic energy. Positive Displacement: Flow is relatively constant regardless of pressure; good for high viscosity, precise flow, high pressure; traps and forces discrete volumes.

Understanding this distinction is paramount when selecting the right type of pump.
