Description of Multi Pump Test Set, Motor Dynamometer

Multi Pump Test Set, Motor Dynamometer is a self contained set for studying the characteristics for various types of pumps. The unit consists of four different types of pumps namely-centrifugal, turbine, reciprocating and axial flow pump, a common storage tank, and measuring instruments. Each pump is driven by a motor dynamometer for measuring TRUE pump input power. Speed control is by an inverter. By manipulating flow control valves and a selector switch, each pump can be operated individually. The unit is floor standing with removeable supports.

Experiments of Multi Pump Test Set, Motor Dynamometer

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