Multi-Stage Barrel Pumps

Multi-Stage Barrel Pumps


Centrifugal, radial split-case, between bearing, multi-stage barrel pumps is a high temperature, high pressure low specific gravity pump for critical services. It has wide hydraulic range and performance of a ring section pump, but demand the design and maintenance attributes of a barrel pump. Specifically designed for boiler feed applications in thermal power stations.
