Centrifugal pumps are capable of evacuating (pumping) a modest amount of air from the suction side of the pump to the discharge side of the pump. Filling the inlet system with fluid or at least filling the pump (wetted pumping elements) will make a major improvement in the pump’s priming capability.

Centrifugal pumps can also be constructed in a manner that results in two distinct volutes, each receiving the liquid that is discharged from a 180. o. region of the impeller at any given time. Pumps of this type are called double volute pumps (they may also be referred to a split volute

Nov 19, 2020 Test headers are used to test a fire pump by providing a route to flow water through the pump without sending it thought the rest of the system. Where a test header connection is used, it sits on the discharge side of the fire pump and is sized according to the fire pumps rated size. The table for centrifugal pump sizing is NFPA 20-2016 table 4.27.

Centrifugal Pump Fundamentals Pumps are broadly classified as kinetic or positive displacement. One of the sub-classifications of the kinetic pump branch is the centrifugal type. It consists of a “wet end” and a drive end. The wet end consists of a rotating impeller within a casing with inlet and outlet connections. It is coupled to either ...
