Recommended water flow velocities on suction sides of pumps
Capacity problems, cavitation and high power consumption in pumps, are often results of the conditions on the suction side.
In general - as a rule of thumb - keep the suction fluid flow speed below the following values:
|Pipe bore||Water Suction Velocity|
