Cavitation

Cavitation occurs when the liquid in the pump turns to a vapor at low pressure. This happens because there is not enough pressure at the suction / lift end of the pump. When cavitation takes place, air bubbles are created at low pressure which can make your pump noisy and cause damage to your pump.

Centrifugal Pump

A centrifugal pump is a mechanical device which is designed to move fluid or water by means of the transfer of rotational energy from one or more impellers within the pump. The momentum of the impeller produces an increase in pressure or flow at the pumps discharge.

Friction Loss

Friction loss is the loss of energy or “head” that occurs in pipe flow due to viscous effects generated by the surface of the pipeFriction Loss is considered as a “major loss”.

Head / Draw

Pump head is a measurement of pump pressure usually written in metres / head and is the maximum height vertically in metres the pump is able to push the water or fluid against gravity. 

EG: If you have a pump with a vertical discharge pipe of 7m and the pump has the specifications of a 7m head, then the pump will pump the fluid up the 7m discharge pipe.
