Construction principle:
4" asynchronous submersible 2 pole electric motor, rewindable, made entirely of AISI 304 stainless steel for the parts in contact with water.
The cooling and lubrication of ball bearings is provided by a special FDA approved liquid.
The stator is enclosed in an AISI 304L stainless steel jacket, attached with steel pins to the upper motor support.
The connector can be removed from the cable to enable simple and quick maintenance tasks.
The cable is certified ACS, WRAS et KTW.
The motor is suitable for use with a speed controller (30 Hz-50 Hz).
Before final installation one must check that:
- Motor power is adapted to the pump being coupled.
- Voltage and phase numbers correspond to the power supply available.
- The main power supply can supportnthe power of the motor.
- For the single phase mode, the capacitor and manual reset overcurrent protection have been placed in the electrical box provided separately.
- For the three phase model, the protection must be provided by the user.
- The motor can be supplied with a PT100 temperature probe.
Oil-filled motor.
