HP 405 MULTI PUMP TEST SET, Motor Dynamometer




This is a self-contained bench top 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.

Instruction manual is also included.

  • Flow rate vs head at various speeds

  • Pump input, output, and true efficiency at various speeds

  • Effect of pulse chamber for reciprocating pump
