FM570 · Multi-Pump Test Apparatus

Experimental Apparatus for the Study of Pump Types and Pump Performance

Learning objectives / experiments

Study of how each pump type moves water and where it is used, such as:
- Gear pump
- Piston pump
- Centrifugal pump
- Axial rotodynamic pump
- Vane pump
- Lobe pump
- Channel impeller pump
Connection of a pump into a hydraulic circuit with quick-release couplings
Measurement of the performance of a pump, such as:
- Head
- Flow rate
- Torque
- Shaft power
- Efficiency
Determination, analysis and comparison of the characteristic curves of the seven pump types
Comparison of positive displacement and rotodynamic pumps under increasing delivery pressure
Determination of the effect of suction throttling on pump performance

FM570: Experimental apparatus for pump testing

Process and instrumentation

Simplified diagram of the water circuit and its instruments

The Sangari eLearning platform controls the motor speed and reads the torque, the shaft speed, the pressures, the water temperature and the flow rate.

Technical specifications

Operating environment laboratory; +5…40 °C; 30…95 % relative humidity, non-condensing

Power supply 230 V, 50 Hz, single phase

Pump types 7, positive displacement and rotodynamic, each on its own base plate

Frame L 1075 × H 1750 × W 730 mm

Weight 149 kg without water in the tank

Drive inverter-controlled AC motor, cradled on a torque arm as an AC dynamometer, driving the pump under test

Torque and speed load cell for the torque, magnetic pickup for the speed

Pressure and flow transducers on the suction and delivery lines, built-in flow meter

Valves throttle valve on the suction side, throttle valve on the delivery side, vacuum breaker on the suction side, pressure relief valve on the delivery side

Couplings quick-release hose and drive couplings, tool-free

Data acquisition The Sangari eLearning platform gives real-time control and data acquisition, together with interactive teaching material. Students set the pump speed and read the suction and delivery pressures, the flow rate, the torque and the shaft speed. The platform then guides them through building the characteristic curve of each pump.
