Horse Power
The
Horsepower required to operate a Positive Displacement Pump has two factors:
WHP =
Flow(GPM) (X) Pressure(PSI) (/) 1714
The
Viscous Horsepower(VHP) - the
power required to turn the rotors, gears, etc. inside the viscous fluid. The Viscous
Horsepower required is determined by the pump design and speed and is supplied by the pump
manufacturer.
HP = WHP +
VHP
