HM 150.16 Series and Parallel Connected Pumps Show data sheet (pdf file) Print page
Technical Description

  In complex systems, pumps can be connected in series or in parallel. In series operation the heads are added together and in parallel operation, the flow rates of the pumps are added.
  With HM 150.16 pumps are studied individually, in series and in parallel.
  The experimental unit contains two identical centrifugal pumps and an intake tank with overflow. The overflow ensures a constant suction head in the tank, regardless of the water supply. Ball valves in the pipes allow easy switching between series and parallel operation.
  Intake and delivery pressures of the two pumps and the pressure in the water drain pipe are displayed on manometers.
  The experimental unit is positioned easily and securely on the work surface of the HM 150 base module. The water is supplied and the flow measured by HM 150. Alternatively, the experimental unit can be operated by the laboratory supply.
  The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments.
