Description

The D series multistage pump is a horizontal and multistage pump. It uses several impellers in order to significantly improve the pump head.

This pump series is traditionally used to convey liquids that are similar to clean water- as in they contain no solids, and the drainage features a solid particle content that is 2% less, and any solid particles are smaller than 0.5mm. This makes it ideal for use in mines, steel mills, and urban water supply and drainage projects.
