HM 150.04 Centrifugal Pump Show data sheet (pdf file) Print page
Technical Description

  Centrifugal pumps are turbomachines that are used for conveying fluids. The HM 150.04 unit can be used to study a centrifugal pump and to record a typical pump characteristic curve.
  The experimental unit includes a self-priming centrifugal pump, a ball valve on the delivery side and manometers on the intake and delivery side. It is driven by an asynchronous motor with variable speed via frequency converter. A ball valve is used to adjust the delivery pressure.
  In experiments, the operating behaviour of the pump as a function of the flow rate is studied and displayed in characteristic curves. The motor's speed and electrical power are displayed digitally. Intake and delivery pressures are displayed on two manometers.
  The experimental unit is positioned easily and securely on the work surface of the base module HM 150. The pump draws in water from the tank on the base module HM 150. The flow rate is determined volumetrically by flowing back into the measuring tank on HM 150.
  The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments.
