Booster Pump vs Pressure Pump

A good way to tell if you are using a booster pump or a pressure pump is by looking at the instructions that come with the product. The packaging will usually say something like “fill to manufacturer’s specifications” or “fill to 80% of capacity”. These are both general instructions and they apply to both types of pumps. However, a pressure pump will have a much higher percentage such as 90% or 100%. A booster pump is not going to have a very high percentage because it is only used to add more water to an existing water supply. A pressure pump is much more powerful and can actually force water out of the way if there isn’t enough water in the line.

What is Booster Pump?

booster pump systemA booster pump is a small electric or hydraulic pump that increases the flow of fluid as well water in a pipe. It is an auxiliary pump used for conveying water or another liquid from one point to another, especially when the main pump has insufficient power to do the job. A typical example is a pool with a weak flow rate (less than 3 GPM) and the main pump that is too small to handle the volume of water required to fill it up. In such cases, you would need a larger pump like a booster to get the job done.

Booster pumps may be electrically powered or gas-powered. There are two major types of boosters:

  1. Centrifugal and
  2. Axial flow.

They both use a single rotating impeller to create a flow that is directed tangentially to the impeller axis. Boosters are available with either fixed, variable, or variable speed drives.

These pumps have a variety of different designs and applications. Some of them are capable of discharging a continuous flow of clean, fresh water at a rate of up to 10 million gallons per hour. This pump is very useful for applications that have low waste contamination.

There are three types of booster pumps:

  1. Single-acting booster pumps are designed to boost the fluid pressure of a single pipe.
  2. Double-acting booster pumps are used to boost the fluid pressure of two or more pipes.
  3. Triple-acting booster pumps are designed to boost the fluid pressure of three or more pipes.

Booster Pump Applications

Booster pumps can be used to supply additional flow to a system when the flow is insufficient, to compensate for losses due to friction, and to provide flow control when there is a demand for flow.

  • They are used in municipal water systems and waste-water systems.
  • They are most often employed to augment pumping stations where the pressure head is not sufficient for the desired level of delivery.
  • They can be used for backflow prevention, reverse osmosis, and process recovery.
  • A common application is in oilfield production, where they provide lift and control of injection water.
  • Another example is in food processing, where they are commonly used in aseptic bottling operations to provide a constant, controlled flow of sterile water for cleaning.
  • They are also widely used in the food industry because they are able to provide cleaner, safer, and more economical process water for a wide range of applications.
  • Booster pumps are typically used to drain water from the bottom of a tank or vessel.

What is a Pressure Pump?

Pressure Booster PumpA pressure pump is a device that creates a continuous stream of water by using a spring and a diaphragm or a piston. It is an electrical device that raises water from a lower level to a higher one. Pressure pumps can enhance the pressure of a stream of water, improve water pressure and make it flow more effectively. They work by creating a vacuum in the system that creates high water pressure. This is the reason why they are often used to irrigate lawns or gardens.

Pressure pumps allow a lot of water to flow, and they don’t stop the water flow at all. A good example of how a pressure pump works is in a showerhead. In this case, a pressure pump is used to create pressure so that you can take a shower with ease.

Pressure Pump Applications

It’s usually used in wells, aqueducts, and other similar structures, where it is needed to lift the water to a higher elevation.

  • A pressure pump is an important device in most irrigation systems.
  • They are used to clean out sewers and remove wastewater from factories. In other words, they are used to get rid of water pollution.
  • They are used to improve the quality of drinking water.

Key Differences Between Booster Pump and Pressure Pump

What is the main difference between a pressure pump and a booster pump? It’s the size. A pressure pump is much larger than a booster pump. Here are the other differences included:

  1. A pressure pump has a much larger chamber than a booster pump.
  2. A pressure pump also has a much higher working pressure.
  3. It can deliver a much higher flow rate of water. In fact, some pressure pumps can deliver up to 1,000 gallons per minute!
  4. A pressure pump is necessary for any plumbing project that involves moving a lot of water. On the other hand, a booster pump is mainly used when you are simply trying to get a small amount of water from one place to another.
  5. Pumping water with a booster pump may only give you 7 to 10 psi while pumping water with a pressure pump could give you 50 to 60 psi.
  6. A pressure pump is a much better choice than a booster pump. It is because a pressure pump has a larger impeller. A bigger impeller means that the pump will have more power.


A pressure pump is the most efficient way to add water to a water system. It is the most powerful way to add water to a water system. It will also add a lot more water to the water system. A pressure pump will force almost all the water out of the way if there isn’t enough water in the lines to keep the pump from getting choked up.
