Compact Multi Pump Test Set: Inverter Speed Control. This is a compact self-contained bench top set for studying the characteristics for various types of pumps.

The unit consists of four different types of pump namely-centrifugal, turbine, reciprocating and axial flow pumps and a common storage tank, measuring instruments. Speed control is by an advanced inverter. By manipulating flow control valves and a selector switch, each pump can be operated individually.

Instruction manual is also included.

TYPICAL EXPERIMENTS

Flow rate vs head at various speeds.
Pump input, output, and overall efficiency at various speeds.
Effect of pulse chamber for reciprocating pump.
