Overview

The MPM08 is a high-power 8-inch (200 mm) three-phase water-filled motor for large borewells, deep lifts and continuous industrial duty — water supply schemes, irrigation systems, food processing and more. 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. This 60 Hz version runs at 3450 rpm and spans 20 to 150 HP on 380 V or 460 V supply, with DOL and star-delta starting.

FAQ

Is this the 50 Hz or 60 Hz version?

This page covers the 60 Hz, 3450 rpm rating tables (380/460 V). For the 50 Hz, 2880 rpm version, see the MPM08 Water Filled (50 Hz) page.

What borewell size does the MPM08 fit?

It's an 8-inch (200 mm) motor (188–192 mm body depending on rating), so it fits 200 mm (8") and larger borewells.

What power options are available?

Three-phase from 20 to 150 HP at 60 Hz / 3450 rpm, on 380 V or 460 V supply, with DOL and star-delta starting. See the Technical Data tabs.
