Submercible Pump Test Rig
Product Code : EL-HML-11059
Quick answer: The submersible pump test rig lets students test a 1 HP submersible pump, the motor-and-pump unit that works fully under water in wells and sumps. They find overall and pump efficiency and plot head and efficiency against discharge, using a 60 litre stainless steel measuring tank and an electronic stop watch. Lab Exports manufactures it in Delhi for engineering colleges, polytechnics and TVET institutes.

How the submersible pump test is done
A submersible pump has a sealed motor close-coupled to a centrifugal pump, and the whole unit sits below the water surface. Because it pushes water up instead of drawing it through a suction pipe, it needs no priming and is not limited by suction lift, which is why it is the usual choice for borewells and deep sumps.
On the rig, the pump delivers from the supply tank through GI or PVC piping to the measuring tank. The delivery pressure gives the head, the timed rise on the piezometer scale gives the discharge, and the panel instruments give the input. Output power is rho x g x Q x H, and the efficiency curves show how the pump behaves as the delivery is throttled.
- Fill the 90 litre supply tank so that the pump is fully submerged.
- Switch on from the control panel and open the delivery.
- Read the delivery pressure gauge for the head.
- Time the rise in the measuring tank with the electronic stop watch.
- Throttle the delivery in steps, repeat the readings, and plot head and efficiency against discharge.

Frequently asked questions
What tank capacities does the submersible pump test rig have?
The supply tank holds 90 litres and the measuring tank 60 litres, both in stainless steel.
Why does a submersible pump not need priming?
It is already under water, so the pump casing is always full and the pump pushes water up rather than drawing it through a suction pipe.
