DM(R) Series Slurry Pump

Double casing construction. It is featured with high efficiency, wear-resistance, stable performance and excellent interchangeability. The material of liner and impeller adopts wear-resistant metal or rubber, discharge branch can be positioned at 8 different positions at intervals of 45 degrees, the pumps may be installed in multistage design, may be driven by belt or direct coupling. The seal of shaft may be adoptable of gland seal, expeller seal or mechanical seal. Pump should rotate clockwise viewing from driving end.

Application of Horizontal Pump

Delin DM(R) series slurry pumps are suitable for delivering abrasive middle and low density slurries in metallurgical, mining, coal and power industries, etc. For example, slurry delivering in mining, metallurgical, power plant, steel mill and chemical industries, etc.

Features of Horizontal Pump

1. DM(R) series slurry pump is designed with double casing.

2. High efficiency, wear-resistance, stable performance and total interchangeability are main features of this series horizontal pump.

3. The material of liner and impeller adopts wear-resistant metal or rubber for our horizontal pump.

4. Discharge branch can be positioned at 8 different positions at intervals of 45°.

5. Similar to our other series horizontal pump, DM(R) series slurry pump can also be installed in multistage design, and driven by belt or direct coupling.

6. The seal of shaft can adopt gland seal, expeller seal or mechanical seal.

7. The pump should rotate clockwise viewing from driving end.
