Multistage Centrifugal Pump Test Rig

Multistage Centrifugal Pump Test Rig The setup is designed to study the performance of Multi stage centrifugal pumps.

Set up consists of a multi stage centrifugal pump coupled with DC motor & drive, supply tank, measuring tank & pipe fittings for closed loop water circulation. There are 2 separate pumps connected to DC motor and drive and can be connected in series and parallel to stimulate different combinations. Pressure and Vacuum gauges are connected on delivery and suction side of each pump for the purpose of measurement. Swinging Field Dynamometer arrangement for direct torque measurement using dial type spring balance is made for individual pump. The flow rate of water is measured using measuring tank and stop watch provided Experiments The Centrifugal Pump Test Rig allows the students to understand the performance benefits of Centrifugal Pumps in parallel & series mode as under: Speed Vs Discharge Head Vs Discharge at various speeds. Efficiency curves at various speed and heads Utilities Required Electric supply Provide 230 +/- 10 VAC, 50 Hz, single phase electric supply with proper earthing. (Neutral – Earth voltage less than 5 VAC.), 5A, three pin socket with switch for pump. Water supply Tap water connection ” BSP Distilled water @ 180 liters (optional)
