description

The HM 284 demonstration unit facilitates the measurement of pump curves in various operating modes. The unit comprises 2 centrifugal pumps that are connected together via a system of pipes. Shut off valves permit the pumps to be operated in series or in parallel. Electronic sensors provide relevant pressures and  the temperature of the pumped medium are measured values. The software for data acquisition and visualisation makes the experiments especially clear and enables fast execution of experiments with reliable results.

 

Learning Objectives / Experiments

- investigation of the operating behaviour of pumps
  * on the operation of one pump
