Constant Pressure Pumps
City-style water pressure from a well. The pump varies its speed to match your demand.
Constant pressure pumps are available in submersible, end suction, and vertical centrifugal designs. They incorporate a VFD (variable frequency drive) along with a pressure transducer to vary the actual speed of the pump according to demand, providing a steady, consistent pressure output.
Practical upshot: the shower doesn't flinch when the washing machine kicks in. And since only a very small pressure tank is needed, the install space is minimal, a real advantage in tight mechanical rooms.
