Booster Pumps

What Are Booster Pumps?

A type of centrifugal pump that helps increase the pressure and volume of water that flows from one place to another in a pipeline. They are designed to help pumping systems achieve higher flow rates and overcome high system head (pressure). They are used in many process applications, where the pressure (head) required for the service is more than one pump can deliver, or where a second pump is required to make sure that the pumps do not cavitate. And depending on the flow and head (pressure) requirement there are different types of booster pumps that can be used – end suction, horizontal split case, multistage, or vertical turbine. They generally work within the following ranges:

  • Flow rate ranges between 5 and 10,000 gpm
  • Total head (pressure) ranges between 200 and 7,500 ft
  • Horsepower ranges between 1 and 5,000 hp

How Does a Booster Pump Work?

Booster Pumps rely on impellers that move water by drawing the pumped fluid into the intake of the pump, and to boost its pressure as the fluid passes through the impeller and the volute or diffuser casing. They work in conjunction with other pumps, meaning by themselves they cannot transport any fluid in a system. They are designed only to “boost" the performance of an existing pumping system. Some are single-stage and others are multi-stage booster pumps.

Single-stage booster pumps have only a single impeller. These are generally used in applications where the amount of additional pressure (head) is low. They are used in private residences or other buildings that are far from the municipal water supply, or where water pressure at the building is inadequate.

Multi-stage booster pumps have more than one impeller and are used to move water up to substantially higher elevations or much longer pipelines. These booster pumps are used to boost water supply in hilly areas, for both agricultural, commercial, and residential uses. They’re also essential in tall buildings.

Typically, booster pumps are used in water systems or applications that have low waste contamination. They have a variety of commercial, municipal, and military applications and are used in a range of industries, including aerospace, mining, and food processing.
