For a given flow rate, there must be a minimum
fluid head pressure supplied to the pump to prevent
cavitation. This minimum head is shown on the
Performance Curve, labeled as NPSHr. The units
are feet WC (Water Column) absolute. The NPSHa

of your system must be greater than the NPSHr to
prevent cavitation and therefore increase efficiency
and the life of you pump. To calculate the NPSHa of
your system, use the following equation:

a

a is the absolute pressure on the surface of the liquid in the supply tank. Typically, this is atmospheric

pressure for a vented supply tank, e.g. 34 feet at sea level.

H

H

Hzz

z is the vertical distance in feet between the surface of the liquid in the supply tank and the centerline of the

pump inlet. Value should be positive if the level is higher than the pump and negative if the level is lower
than the pump. Always be sure to use the lowest level the liquid can reach in the tank.

H

H

Hfff is the total of the friction losses in the suction piping.

H

vp

vp is the absolute vapor pressure of the liquid at the pumping temperature. For example, for water at

70°F, the vapor pressure is 0.86 feet.
