Centrifugal Pump Test Rig

Instrumented pump set for measuring head, flow, input power, and efficiency across the operating range.

A centrifugal pump on a closed circuit with throttling, suction and delivery pressure measurement, flow measurement, and input power indication, so a class plots the characteristic curves from its own readings. A second pump is specified where the syllabus includes series and parallel operation, which is the comparison a fluid machinery course is usually built around.
