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%.

Boosters pumps and pressure pumps are two of the most commonly used types of pumps in various applications. Understanding the differences between the two can help you make an informed decision when it comes to choosing the right pump for your needs. The purpose of this blog post is to educate you on the key differences between booster pumps and pressure pumps and help you choose the right pump for your requirements.

Understanding the 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 a 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.

Depending on working stages booster pumps are classified as follows:

  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.

Advantages of using a booster pump include improved water flow, increased water pressure, and improved water delivery in low-pressure systems. Additionally, booster pumps are usually compact and easy to install, making them a convenient solution for a variety of applications.

Booster Pump Applications

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.

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.

Understanding the 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.

Advantages of using a pressure pump include improved water pressure, consistent water delivery, and the ability to handle a wide range of applications. Additionally, pressure pumps are usually more durable and long-lasting compared to booster pumps, making them a reliable solution for many applications.

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.

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. 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.

Key Differences between Booster Pumps and Pressure Pumps

Here are the key differences included:

A pressure pump has a much larger chamber than a booster pump.

Design and construction

The design and construction of booster pumps and pressure pumps differ, as well as the flow rate and pressure they can produce. Booster pumps are designed to increase the water flow and pressure in low-pressure systems, while pressure pumps are designed to maintain constant water pressure in a system.

Delivery and distribution

Another key difference between the two is water delivery and distribution. Booster pumps are designed to deliver water from a storage tank or well to a location where the water pressure is too low. Pressure pumps, on the other hand, are designed to maintain constant water pressure in a system, regardless of the flow rate.


The applications and suitability of booster pumps and pressure pumps also differ. Booster pumps are suitable for applications that require increased water flow and pressure, such as irrigation, fire protection, and commercial buildings. Pressure pumps are suitable for applications that require constant water pressure, such as water distribution, industrial processes, and water treatment systems.

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.

Choosing the Right Pump for Your Needs

When choosing between a booster pump and a pressure pump, it is important to consider several factors, including the flow rate and pressure requirements, the water source, and the application requirements.

Comparing booster pumps and pressure pumps can help you determine which pump is best suited for your needs. For example, if you need increased water flow and pressure, a booster pump may be the right choice for you. If you require consistent water pressure, a pressure pump may be the better option.


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.
