DF(S) - Type Mining Pump

Description

DF(S)-type mining use wear&corrosion resistent centrifugal multistage pump has features of anti-cavitation,high efficiency,energy conservation,reliable and service long life.Especially applied in mine drainage,pumping solid particle content which is not more than 5%(particle diameter is less than 0.5mm)mine water and other similar liquid.

The pump follows the standards of ISO、API、GB、ASTM and JIS.

Application Area

▪ Salt manufacturing industry

▪ Seawater desalination

▪ Process industry

▪ Power plant

▪ Chemical and petro-chemical industry

Performance Range

Capacity：230-666m3/h

Head：158.3-1153.3m

Matched Power：N=280-2240 kW

Medium Temperature：≤105℃

Structural Characteristics

The pump is first stage impeller of double suction and the radial part segmental structure.The flagstaff connects the suction section,middle section and disgorge section to be a whole part.Pump rotor is constituted by the first double suction impeller,secondary impeller and balancing drum,etc.

Axial force balance:Axial force produced by balance drum and two thrust bearing balance impellers.

Bearing:The drive end uses imported SKF or FAG cylindrical roller bearing radial force, the non-driving end uses two imported SKF or FAG radial-thrust bearing to bear radial force and to balance residual axial force.

Shaft seal:Packing seal or mechanical seal shall be applied according to user’s demand.

Transmission:Driving is proceeded through the flexible diaphragm coupling driven directly by the prime motor.Pump rotates clockwise from the direction of driving end.

Heat dissipation of bearing:Lubricating ring is used to cool lubrication down.The effect shall be better if cooperated with fans and heat radiation rib.
