HP 405B COMPACT MULTI PUMP TEST SET, Inverter Speed Control
GENERAL DESCRIPTION

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.
TECHNICAL DATA
Pumps ratings:
 - Centrifugal pump and motor with maximum flow rate 80 Lpm and maximum head 18 m water
 - Turbine pump and motor with maximum flow rate 30 Lpm and maximum head 30 m water
 - Reciprocating pump and motor with reduction gear, maximum flow rate 15 Lpm at 300 rpm and maximum head 30 m water
 - 69 mm in axial flow pump and motor with metal impeller, guide vanes, shaft and casing, maximum flow rate 400 Lpm and maximum differential head 1.5 m water
Reciprocating pump accessories
  • Pulse chambers with discharge isolating valve
  • Pressure relief valve
Speed control Advanced inverter for controlling and indicating pump speed as well as for calculating motor input power alternatively by selector switches.
Motor for all pumps
Selector switch For operations of each pump alternatively
Measuring instruments
 - Flow rates Water meter and stop watch for centrifugal, turbine and reciprocating pumps
 - Pressures
  • Pressure gauge for centrifugal, turbine and reciprocating pumps at common suction and outlet
  • Differential pressure gauge for axial flow pump
 - Pump speed and motor input power Advanced inverter
 - Sensors with digital display Flow rate for axial flow pump
Power supply 220 V, 1 Ph, 50 Hz. Other power supply is available on request.
OPTIONAL EQUIPMENT
