Booster Pumps are used to further boost the pressure in a system. It may be end suction, in-line circulator, horizontal split case, or a single or multi stage vertical turbine pump. Booster pumps are used in applications where the normal system pressure is low and needs to be increased. These pumps are specifically designed for boosting water pressure in municipal, well water systems, rain water collection systems, and garden and irrigation applications. Booster Pumps are usually located near the source of water somewhere between the building meter and where the water main enters the building. The maximum boost pressure for a pump is in addition to your existing system pressure. For example; if your existing pressure is 30 PSI, and your new booster pump has a maximum boosting pressure of 40 PSI, the total system pressure will now be 70 PSI. Most Booster Pump Systems require a storage pressure tank.

Storage Pressure Tanks perform three main functions: protects and prolongs the life of the pump by preventing rapid cycling of the pump motor (frequent start and stops), provides water under pressure for delivery between pump cycles and provides additional water storage if the water supply is incapable of supplying the required volume during peak demands. Pumps generally fail due to rapid cycling, so without a pressure tank many daily water uses such as washing your hands, or flushing a toilet could trigger the pump to cycle. Over the last number of years Variable Frequency Drives, (VFD), have been incorporated into Booster Pump Systems lowering energy costs and less wear and tear on the pumps and related equipment.


Booster Pumps are almost always a multi-stage pump (has more than one impeller). All other features are quite specific to the application.


Booster Pumps are typically used to boost water pressure from source pressure to pressure required for system. Potable water booster, irrigation booster, cooling water booster, process booster service

Types of Fluids

Booster Pumps pump water and relatively thin liquids (not for thicker liquid or oils). Not normally used for liquids containing solids.


Booster Pumps allow the building up of additional pressure that is required to move liquid a long distance or to use the high pressure for spraying or other services.
