Manual

Our products are manufactured to latest international standards with more emphasis on quality tests at every stage of manufacture.
As the name submersible pump, implies, it is designed to function with fully immersed water. The motor is squirrel cage induction motor would with special PVC/wrap insulated copper wire and is water cooled during operation. The motor is filled with water before insulation, coupled to pump and fitted through delivery pipes to the depth required.3 core flat cable is used and the size of the cable is determined by the HP and current capacity. The axial and thrust bearings are designed sand guard prevents entry of sand and foreign particles inside the motor.
The pump is a multistage centrifugal type with radial or semi axial designed impeller based on the yield of the borewell. The pump casing and impeller are designed to provide smooth flow of water with minimum friction with high operating efficiency. A suitable strainer is provided at the suction end of the pump to prevent entry of foreign particles.
The pumpset is suitable for pumping clear, cold fresh water with maximum permissible sand content of 50gms/cubic meter.More sand content cause premature failure or Motor and pump parts.
Check the direction of rotation as the pumpset will run in both direction. By interchanging any two phase of lead cable will guide you to verify higher discharge decides the correct direction.

General Instructions

Insulation Test

Check the insulation resistance of the coils and 3 core cables. Connect the terminal line of megger to cable lead end and the other lead to clear surface of delivery pipe. The reading on the megger should never be less than 5 mega ohm.

Continuity Test

To check the continuity one lead from the megger to one phase and the other lead to another phase. In this way continuity of all the three combination of the leads ( i.e., RY, RB, BY ) to be verified for continuity.
