HM 305 Trainer Centrifugal Pump Show data sheet (pdf file) Print page
Technical Description

  The trainer HM 305 is a mobile system with a closed water circuit that is intended both for training in vocational colleges and also for laboratory experiments in higher education.

  The system is equipped with a centrifugal pump and various transducers, e.g. the torque on the shaft of the speed-controlled pump motor is measured and indicated on the switch box, as is also the rotational speed, current and voltage. Manometers indicate the pressure on the intake and delivery side of the pump. The flow rate is measured using an magneto-inductive flow sensor. In this way the system provides a whole host of measured data that permit students to perform experiments on the basic principles of a hydraulic circuit.

Learning Objectives / Experiments

- recording of a pump characteristic curve
- recording of a system characteristic curve
- determination of the flow rate by using a

  magneto-inductive flow sensor

- calculation of efficiencies


* Mobile trainer for experiments on the basic

  principles or centrifugal pumps1
* Closed water circuit1
* Pressure, speed, torque and pump power

  consumption available as measured values
