4" submersible pump motor
Water filled - Threephase 230 V

Construction principle:

4" asynchronous 2 pole submersible motor, rewindable, made of AISI 304 stainless steel for the parts in contact with water.

The cooling and lubrication of the thrust bearing and the bushings are ensured by a mixture of water and glycol, as required by the law for the protection for food uses. (Mixture of distilled water and 20% de polypropylene glycol).

The rotor is mounted on a Kingsbury self-centering thrust bearing designed for bearing high axle loads.

The stator is enclosed in an AISI 304L stainless steel sleeve, attached with steel pins to the upper motor support.

The connector can be removed for simple and quick maintenance tasks.

The cable is certified ACS, WRAS and KTW. The motor is suitable for use with a speed controller (30 Hz-50 Hz).

Slide bearings lubricated by water. The axial stop is the tilting pad type (Kingsbury)with carbon disk.

Compensating bellow for volume variation of internal liquid.

Cable with removable connection and water-tight seal.

Before final installation one must check that:

• Motor power is adapted to the pump to be coupled.
• Voltage and phase number correspond to the power supply network available.
• The main power supply can handle the power of the motor.
• For the 50 Hz single phase mode, the capacitor and manual reset electric current protection device have been placed in the electrical panel provided separately.
• For the three phase model, the protection must be provided by the user.

Oil-filled motor
