The Different Types of Plumbing Pumps and Their Uses

Plumbing pumps play a crucial role in many residential, commercial, and industrial applications. These mechanical devices are designed to move fluids through pipes and other systems by converting mechanical energy into fluid energy. Pumps are essential for maintaining water pressure, draining wastewater, and ensuring the proper circulation of fluids in various systems. They can prevent damage caused by excess water pressure or flooding and also contribute to energy efficiency and overall system performance. Now, let’s explore the different types of plumbing pumps and their uses.

Types of Plumbing Pumps

There are numerous types of plumbing pumps available, each with its specific purpose and application. We will discuss some of the most common types, including centrifugal pumps, positive displacement pumps, submersible pumps, and booster pumps.

Centrifugal Pumps

Centrifugal pumps are among the most widely used types of plumbing pumps. They operate by using a rotating impeller to create a flow of fluid, which is then propelled through the system. There are two main subtypes of centrifugal pumps:

Single-stage Centrifugal Pumps

These pumps contain one impeller and are commonly used for applications requiring low to moderate pressure, such as water supply systems, irrigation, and HVAC systems.

Multi-stage Centrifugal Pumps

In multi-stage pumps, there are multiple impellers in a series, which allows them to generate higher pressure. These pumps are typically used in high-pressure applications, like industrial processes or high-rise buildings.

Positive Displacement Pumps

Positive displacement pumps work by trapping a fixed volume of fluid and then forcing it through the system. There are several types of positive displacement pumps, including diaphragm pumps, piston pumps, and rotary pumps.

Diaphragm Pumps

Diaphragm pumps use a flexible diaphragm to move fluid. They are often used for chemical metering, transferring corrosive materials, or pumping fluids with high viscosity.

Piston Pumps

Piston pumps use a reciprocating piston to move fluids. They are commonly used in applications that require high pressure, such as pressure washing or hydraulic systems.

Rotary Pumps

Rotary pumps use rotating components, like gears or lobes, to transfer fluids. They are often used for pumping viscous liquids, like oils or syrups, and are known for their efficiency and smooth operation.

Submersible Pumps

Submersible pumps are designed to operate while submerged in the fluid they are pumping. These pumps are commonly used for draining basements, sump pits, and wastewater treatment systems. They are also used in applications such as fountains, wells, and ponds. Submersible pumps are typically more efficient than other types of pumps because they do not lose energy due to suction lift, which is the process of lifting water from a lower level to a higher one.

Booster Pumps

Booster pumps are used to increase water pressure in a plumbing system. They are typically installed in residential, commercial, and industrial settings where water pressure needs to be boosted for proper distribution and usage. Booster pumps can be used to enhance the pressure in high-rise buildings, water treatment plants, and irrigation systems.

Choosing the Right Plumbing Pump

Selecting the appropriate plumbing pump for your application is essential to ensure optimal performance and efficiency. Here are some factors to consider when choosing a pump:

Factors to Consider

  1. Purpose: Determine the specific use of the pump, such as water supply, wastewater removal, or pressure boosting.
  2. Flow Rate: Identify the required flow rate, which is the volume of fluid the pump needs to move per unit of time.
  3. Pressure Requirements: Determine the necessary pressure or head, which is the vertical distance the fluid needs to be lifted or the pressure required in the system.
  4. Fluid Characteristics: Consider the properties of the fluid being pumped, such as viscosity, corrosiveness, or the presence of solids.
  5. Energy Efficiency: Choose a pump with high energy efficiency to reduce operational costs and minimize environmental impact.
  6. Installation and Maintenance: Consider the ease of installation and maintenance, as well as the availability of spare parts and service support.

Plumbing pumps are essential components in a wide range of applications, from residential water supply systems to industrial processes. Understanding the different types of pumps, their uses, and the factors to consider when choosing a pump can help ensure optimal performance, efficiency, and longevity for your specific application.


  1. What is the difference between centrifugal and positive displacement pumps?

Centrifugal pumps use a rotating impeller to create fluid flow, while positive displacement pumps trap a fixed volume of fluid and force it through the system. Centrifugal pumps are generally more suitable for low to moderate pressure applications, while positive displacement pumps are better for high pressure or high viscosity applications.

  1. How do I know if I need a booster pump?

A booster pump may be needed if you experience low water pressure in your home or building, or if you need to increase the pressure for specific applications like irrigation systems or high-rise buildings.

  1. Can submersible pumps be used for all types of fluids?

While submersible pumps are versatile, they may not be suitable for all fluid types. It is essential to consider the fluid’s properties, such as viscosity and corrosiveness, when selecting a submersible pump for a specific application.

  1. How do I maintain my plumbing pump?

Regular maintenance is crucial for the longevity and performance of your plumbing pump. This may include checking for leaks, cleaning filters and strainers, lubricating bearings, and inspecting electrical connections. Always refer to the manufacturer’s guidelines for specific maintenance recommendations.

  1. How do I determine the right size of the plumbing pump for my application?

To determine the appropriate size of a plumbing pump, you will need to consider factors such as flow rate, pressure requirements, and the characteristics of the fluid being pumped. Consulting with a professional or using online sizing tools can help you make an informed decision.
