HM 300 Basic Centrifugal Pump
Education / GUNT Hamburg / Fluid Mechanics and Hydrology / Hydraulic Fluid Energy Machines /


 The HM 300 testing stand represents a simple pump circuit that enables various experiments to be performed. Amongst other aspects, the model can be used to demonstrate the analogy between a hydraulic circuit and an electrical circuit. The set-up includes a centrifugal pump, a variable-area flow meter, an electronic differential pressure gauge, a valve inserted in the measuring section, a water tank and other fittings. Annular chambers are used for making pressure measurements in the circuit.

Learning Objectives / Experiments
· Recording a pump characteristic curve
· Pressure losses on various fittings
· Pressure losses on valves as a function of the flow rate
