Venting | KSB

Venting is a necessary process which serves to release accumulations of air from pressurised water pipes and allows a centrifugal pump to be primed with the fluid handled prior to its start-up. To this end, centrifugal pumps in suction head operation are equipped with a vent valve or a manually operated air vent at the pump casing's apex.

Centrifugal Pump Operation and Solutions of problems
Centrifugal Pump Operation and Solutions of problems

Centrifugal Pump Protections. A centrifugal pump is dead-headed when it is operated with no flow through it, for example, with a closed discharge valve or against a seated check valve. If the discharge valve is closed and there is no other flow path available to the pump, the impeller will churn the same volume of water as it rotates in the pump casing.
