This Submersible Pump Test Rig is designed to help study the working and performance of a submersible pump. It includes a submersible pump connected to an electric motor, along with a supply tank, a measuring tank, and pipe fittings arranged in a closed loop for water circulation. To measure pressure, both pressure and vacuum gauges are installed on the pump’s delivery and suction sides. The amount of water flow is calculated using the measuring tank and a stopwatch provided with the setup. This system is ideal for learning how submersible pumps work in a simple and practical way.

Experimental Objective

Determine the overall efficiency and pump efficiency of the submersible pump.

Plot graphs of head versus discharge and pump efficiency versus discharge.
