Series and parallel pump experimental apparatus (variable speed)
This is a compact tabletop experimental device designed to test the operation characteristics of two centrifugal pumps in series and parallel operation, or a single pump. The device consists of electric motors (variable speed) that drive each pump individually, a transparent acrylic water storage tank and valves (for each pump inlet and outlet), pressure sensors (for each pump inlet and outlet), and a flow sensor (for the drainage outlet). The impeller part of each pump is designed with a transparent cover for observation, allowing for demonstrations of cavitation. The included control box allows for variable adjustment of motor speed and digitally displays rotation speed (rpm), torque (N.m), output (W), pressure (bar), flow rate (L/s), and temperature. Additionally, the included data acquisition software VDAS can collect and analyze various data in real-time on a PC (sold separately). *There is also an analog type of experimental device similar to the H53V. H52 Series and Parallel Pump Experimental Device (Constant Speed) The H52 operates with a constant motor speed and is composed of an analog pressure gauge and a float-type flow meter.
