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.
