Submersible Motor

MPM10 Water Filled Submersible Motor

A 10-inch (250 mm) three-phase water-filled submersible motor — the top of our range, for the largest borewells and the heaviest continuous industrial duty. Filled with clean, anti-corrosive water that cools and lubricates the motor, with high-efficiency windings, a graded cast-iron housing, stainless-steel shaft and heavy thrust bearing for very high axial loads. 110 to 250 HP at 50 Hz, with DOL and star-delta starting.

10" / 250 mm 110–250 HP 50 Hz 3-Phase · IP 58/68

Overview

The MPM10 is the largest motor in the range — a 10-inch (250 mm) three-phase water-filled motor for the biggest borewells, deepest lifts and most demanding continuous duty in bulk water supply, large-scale irrigation and heavy industry. Filled with clean water and an anti-corrosive additive, it cools and lubricates itself as it runs, while high-efficiency windings hold operating cost down. A graded cast-iron housing with a precisely fitted bush, heavy-duty thrust bearing and stainless-steel shaft carry very high axial loads, including horizontal pump-set applications. Ratings span 110 to 250 HP, with DOL and star-delta starting, all at 50 Hz.

Highest Power in Range

110–250 HP three-phase with high-efficiency windings for low running cost on heavy continuous duty.

Water-Cooled & Lubricated

An anti-corrosive water fill cools and lubricates the motor for clean, oil-free running.

Heavy-Duty Build

Graded cast-iron housing, stainless-steel shaft and a thrust bearing sized for very high axial loads.
