DG Horizontal multistage pump

Horizontal multistage boiler feed pump

Is Suitable to convey water with temperature below 105 degree Celsius and other similar fluids.

DG horizontal multistage pump is a segmented single-suction multistage centrifugal pump. High efficiency, wide range of performance, safe and stable operation, low noise, long life, easy installation and maintenance, etc. For the conveyance of fresh water or other liquids similar in physical and chemical properties to water. It can also be used to transport hot water, oil, corrosive or abrasive media by changing the material of the pump's flow components, sealing form and adding a cooling system. Pump meets with JB/T1051-93 Multistage clean water centrifugal pump Type basic Parameters and standard.

Pumped medium

It can be used for conveying clean water without solid particles (abrasive matter), without suspended matter or other liquids with physical and chemical properties similar to clean water.

shaft seal

The shaft seal adopts soft packing seal with cooling water, or mechanical seal according to user's requirement.

bearing balance

The rotor of DG medium pressure pump is supported by the rolling bearings at both ends of the pump shaft. The rotor is lubricated with thin oil and cooled with circulating water, and the axial thrust of the rotor is automatically balanced by a balancing plate. Isostatic backwater is returned to the pump suction section through isostatic backwater pipe.

The rotor of distributed type multistage boiler feed pump is supported by sliding bearings at both ends of pump shaft. The rotor is lubricated with thin oil and cooled with circulating water, and the axial thrust of the rotor is balanced with a balance plate. A return pipe is arranged between the balance chamber and the front section.

DG type multistage boiler feed pump rotor is supported by sliding bearings at both ends of the pump. The bearing is compulsively lubricated, the pump itself is equipped with an oil system, and the axial thrust of the rotor is balanced by a balancing plate. And with thrust bearing, used to withstand the residual axial force caused by the change of working conditions, between the balance chamber and the suction pipe is equipped with return pipe.
