This series of pumps are horizontal single suction multistage segmented centrifugal pumps, which adopt the hydraulic model of high-efficiency and energy-saving products recommended by the state. They are designed and produced completely according to MT / t114-2005 multistage centrifugal pumps for coal mines and JB / t1051-93 types and basic parameters of multistage clean water centrifugal pumps. The pump has the advantages of high efficiency, wide performance range, safe and stable operation, low noise, long service life, convenient installation and maintenance.

This series of pumps are assembled with carbide balance ring and lining ring.

According to its application scope, it is mainly divided into the following types:

1) D-type: D-type pump is used for conveying clean water with no solid particles and temperature lower than 80 ℃ or liquid with physical and chemical properties similar to clean water. It is suitable for mines, factories and urban water supply and drainage projects.

2) MD type: MD type is used for conveying neutral mine water and other similar sewage with particle content ≤ 1.5%, particle size ≤ 0.5mm and temperature of - 20 ~ 80 ℃.

3) DF type: DF type pump is used for conveying corrosive liquid without solid particles and at a temperature of - 20 ℃ ~ 105 ℃. The allowable pressure at the pump inlet is less than 0.6MPa. The user can reasonably select the pump material, sealing form, pump structure and determine the motor capacity according to the name, concentration, specific gravity, operating temperature and pump inlet pressure of the conveying medium.

Model meaning:

Example: D (DF, Dy, MD) 600-60 * 6

D - multi stage clean water centrifugal pump

DF - mining corrosion-resistant multistage centrifugal pump

Dy - multi stage centrifugal oil pump

MD - mine wear-resistant multistage centrifugal pump

600 - flow at design point is 600m3 / h

60 refers to the design point, and the single-stage lift is 60m
