Multistage Centrifugal Pump Maintenance

4.0 1 Review SKU: GMMSC00CENDuration: 60 Minutes

Centrifugal pumps are among the most common types of pumps used in industrial facilities. A centrifugal pump has a rotating impeller that circulates fluid within a casing and directs it to an outlet, or discharge, pipe. A singlestage centrifugal pump has a single impeller and develops relatively low discharge pressures. A multistage centrifugal pump has two or more impellers and develops relatively higher discharge pressures. Although multistage centrifugal pumps are generally larger and more complicated than single-stage pumps, they operate under the same basic principles. This course describes the general operation of multistage centrifugal pumps and explains how to identify problems with these units. The disassembly and reassembly of two types of multistage centrifugal pumps are also covered.
