HP405 MULTI PUMP TEST SET, Motor Dynamometer

This 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.

  • Flow rate vs head at various speeds.
  • Pump input, output, and true efficiency at various speeds.
  • Effect of pulse chamber for reciprocating pump.
  . Pumps :                
    - Centrifugal pump with maximum flow rate 80 lpm and maximum head 18 m water.    
    - Turbine pump with maximum flow rate 30 lpm and maximum head 30 m water.    
    - Reciprocating pump with reduction gear, maximum flow rate 15 lpm and maximum head 30 m water.
