MD Centrifugal Multistage Pump

Product Overview

The MD Centrifugal Multistage Pump is a wear-resistant multistage centrifugal pump specially designed for coal mine water supply and drainage applications. It is mainly used for conveying clean water and neutral mine water containing up to 1.5% solid particles, with particle sizes below 0.5 mm and a maximum liquid temperature of 80°C.

With a multistage construction, the MD series provides high-head pumping performance across a wide flow range. In addition to coal mining, it is suitable for water supply and drainage applications in mines, factories, and cities.

The MD series implements the MT/T114-2005 standard for multistage centrifugal pumps for coal mines, supporting its application in demanding mining environments.

Important: A flameproof motor must be used when the pump is installed underground in a coal mine.
