Bowl Casing

The bowl casing of a Vertical Shaft (VS) pump is the housing located at the lowest part of the pump, guiding fluid from the inlet to the impeller with minimal energy loss. Made from materials such as cast iron or stainless steel, it protects rotating components, allows capacity adjustment through the number of impellers, and is designed to operate at significant depths. Proper design and material selection greatly influence the pump’s efficiency, durability, and service life.
