Designed for deep-well turbine pumps, our three-phase asynchronous squirrel-cage rotor motors excel in handling significant axial forces, ensuring reliable performance for vertical solid-shaft pump systems.

Installation Instructions

Screw the coupling bolt into the pump coupling, ensuring it remains vertical.
Remove the motor’s top cover.
Clean the mounting surface, then vertically align the motor over the pump shaft onto the base flange support. Secure with fastening bolts.
Firmly connect the motor to the pump shaft coupling.
Inject high-quality bearing lubricant (viscosity 13–16.5 mm²/s) through the motor’s oil fill port.
Add lubricant per the motor’s label, typically below half the sight window level, unless specified otherwise.
Excess lubricant may flow into the motor via the shaft sleeve or be flung out during rotation—this does not affect normal operation, so clients can use with confidence.
After verifying the installation, replace and tighten the motor’s top cover.

Operational Notes

Equipped with thermal and short-circuit protection devices; set current according to the nameplate.
If frequency deviates by 1% or voltage by 5% from nameplate values, continuous rated power cannot be guaranteed.
Whether loaded or not, the motor must not produce irregular sounds or vibrations. Operating temperature must not exceed 95°C.
