multi-stage centifugal pump

Overview:

GD and D type pumps are used for delivery of water without solid partical. DF and D2 type pumps are used in mine for delivery of acidic pit water. The temperture of all mediums can not be higher than 80℃.

Performance range:

flow rate: Q=100~515m³/h (GD, D type )

              Q=27~346m³/h (DF, D2 type )

head: H=66~700m (GD, D type )

         H=66~459m  (DF, D2 type )

Structure:

This pump is horizontal, single-suction, multi-stage segmental Centifugal Pump. Water inlet can be horizontal or vertical and water outlet is vertical. Suction casing, midpiece and spit out section are connected through poles.

Pump rotor is consist of impeller and balancing disc on the shaft, the whole rotor is supported by 2 roller bearings at both ends of the pump. The bearing is lubricated by oil. The axial thrust is balanced by balancing disc.

Shaft Seal:

Stuffing box at both ends of shaft 

Pump soft packing seal, shaft seal with the sleeve can be replaced.

LDTN condensate pump is equipped with multiple water lubricated bearings, rotor radial force to bear. LDTN (AB) 13 P-type pump has a balance on drums plus one pair of angular contact ball bearings to balance the axial force, the other motor thrust bearing axial force. 

Coupling:

Asked the internal pump rotor shaft coupling with a cylindrical ring-type connection, the pump rotor and motor shaft connected in two ways; motor axial force, rigid coupling with flange connection; pump itself balance the axial force, connected with a flexible coupling.

Seal: 

For soft packing seal + seal can also special order designed mechanical seal.

Transmition:

N type Condensate Pump is driven by motor through flexible coupling. Direction from the drive, the pump is clockwise for vertical, and counterclockwise for horizontal.

Material:

pump body & cover---------------cast iron

casing ring & shaft sleeve-------cast iron

impeller-------------------------------silicon brass

inducer-------------------------------aluminum-iron brozen

shaft----------------------------------high quality carbon steel
