Q:

How do water pressure booster pumps work?

A:

Quick Answer

Water pressure booster pumps work in coordination with pressurized expansion tanks that contain a rubber bladder. The pump transfers water to the tank on the bladder side that causes the air to get compressed, which in turn results in the water becoming more pressurized.

Full Answer

Water pressure booster pumps increase the pressure within fluid circulation systems. The expansion tank acts as a storage reservoir but also maintains an equilibrium pressure in the system. The rubber bladder in the tank, filled with air from the air compressor, maintains the stable pressure. The rubber bladder also ensures that the water pump avoids hard cycling, thus protecting it from burning out.

The control pressure switch is sensitive to the water pressure within the tank. As soon as the pressure drops below a specific preset value, the switch closes and the pump starts to push the moving source water into the pressure setup. Once the pressure increases to the required limit, the switch opens up, and the pump stops its operation.

The booster pumps are manually controlled or an on-demand system controls the operation. The operation of a manual system includes manually turning on a switch to increase the water pressure. The on-demand system continuously monitors the water pressure and automatically turns on when there is a requirement for additional water pressure.
