MPM07 — 7" Water Filled Submersible Motor
Majestic Pump's 7-inch (175 mm) water-filled submersible motor — a high-power, three-phase borewell motor for deep wells and heavy continuous duty, water-lubricated for clean running, from 10 to 75 HP at 50 Hz.
MPM07 Water Filled Submersible Motor
A 7-inch (175 mm) three-phase water-filled submersible motor for large borewells, deep lifts and heavy continuous 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 high axial loads — including horizontal pump sets. 10 to 75 HP at 50 Hz.
Overview
The MPM07 is a 7-inch (175 mm) three-phase water-filled motor for big borewells and demanding continuous duty across agriculture, industry and bulk water supply. 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 high axial loads, including horizontal pump-set applications. Ratings span 10 to 75 HP, with star-delta starting on the larger frames, all at 50 Hz. The motor accepts both 6" and 8" pump connections.
