Product Description
General description
AquaBoost CS pumping package
Depending upon the pumping capacity required, a simplex (one-pump) type or a duplex
(two-pump) type is used. In both types, a pressure switch starts and stops the pump.
The AquaBoost Constant Speed pumping package operates pumps across the line to
increase the domestic water pressure up to 55 psi above that of the city water pressure.
AquaBoost VS pumping package
The AquaBoost Variable Speed pumping package can precisely match the pump
discharge pressure to the system pressure by varying the speed of the pump. This is
accomplished by using the variable-speed controllers such as the AquaBoost II and
Aquavar CPC.
The pressure transducer monitors the system pressure, allowing the controller to start and
regulate the pump speed. AquaBoost VS is available in simplex and duplex configurations.
