Product Code:
Fluid0032
Description:
Variable Speed Centrifugal Pump
Contains a centrifugal pump, a ball valve on the delivery side and manometers both on intake and delivery sides. Drive is provided via a speed-controlled asynchronous motor with frequency converter. The delivery pressure is adjusted with the ball valve. The speed and the electrical power at the motor are displayed digitally.
The water supply and volumetric flow rate measurement are provided by the Basic Hydraulics Bench.
Learning Objectives / Experiments
- Measurement of intake and delivery pressure
- Recording the pump capacity
- Determination of pump efficiency
- Effect of speed on pump capacity and delivery
Pressure
- Recording pump characteristic curves
