The solution to your
pumping challenges

MX Series



Subteck submersible motor is a three-phase asynchronous motor with a short circuit rotor. It is designed as a wet-running motor with a watertight insulated winding. All motors are rewindable. 8’’ motor connection is according to NEMA standard.

The bearings are lubricated by the motor filling. That is a mixture of glycerine and water. Glycerine is biodegradable and secures the anti freeze protection up to -25 °C. If necessary, it can be changed with pure drinking water.

Axial down thrusts is absorbed by the axial thrust bearing with individual tilting pads. Motors are encapsulated by a high quality mechanical seal. A reliable balance system grants the pressure compensation between motor and its environment.

The motors are completed with pressure-water tide cable. They are inside-earthed. Construction complies with VDE-regulations and the motors are conform to the EC declaration of conformity as defined by machinery directive 2006/42/EEC.

Motors are usable in horizontal and diagonal position depending of the nominal power, they are working electrical clock- and anticlockwise.

A high efficiency guarantees lowest operating costs.

For all the motors Subteck holds a detailed supply of control and monitoring equipment.

Frequency transformer operation


Every Subteck motor is usable for frequency transformer operations. Following recommendations should be considered:

  • The frequency transformer must be conform to the nominal currency of the submersible motor;
  • The maximal working range from 30 Hz up to 60 Hz, corresponding speed from 1.740 up to 3.460 1/min;
  • The using of a sine-wave generator protects against high voltage peaks;
  • The minimum rate of flow must be 10% of the nominal rate of flow of the pump.

Soft starter operation


Soft starters are very qualified to start a submersible motor. They grant:

  • reducing of starting current;
  • avoidance of water hammer while starting causing switch-off of the pump.
