About this calculator
Overview
Pump power is the work done by the pump to move a specific volume of liquid against a specific pressure (head). Total power required also accounts for mechanical and hydraulic losses.
💡
Pro Tips
Head (H) refers to the height the liquid is lifted plus friction losses.
Efficiency (η) is the ratio of power delivered to the fluid vs power drawn by the motor.
Water has a Specific Gravity (SG) of 1.0.

Fun Facts
"The 'Centrifugal' pump is the most common industrial pump type."
"Pump power increases with the cube of the rotation speed (Afinnity Laws)."
