Pump output, water horsepower or hydraulic horsepower (hp) is the liquid horsepower delivered by the pump, and can be calculated as follows: Hydraulic power hp = Q (m3/s) x (hd – hs in m) x ρ (kg/m3) x g (m/s2) / 1000. Where: Q = flow rate. hd = discharge head. hs = suction head. ρ = density of the fluid.Web

The diffuser (also called as volute) houses the impeller and captures and directs the water off the impeller. Water enters the center (eye) of the impeller and exits the impeller with the help of centrifugal force. As water leaves the eye of the impeller a low-pressure area is cre-ated, causing more water to flow into the eye.Web
