O4I B
Submerged IP68 motors for coupling to 4” well pumps, with coupling according to the NEMA MG-1.18.388 standard
These motors have a rotor bathed in liquid cooling oil compatible with food use and with FDA approval. The stator is rewindable, and allows for reliable, long-lasting operation. The sturdiness of the motor is combined with the sand-protection system for the shaft, with a mechanical seal and elastomer windback. Includes a power cord with removable connector. Available in single-phase presentations of up to 2.2 kW and up to 7.5 kW for three-phase versions.
