A FULL RANGE OF PRODUCT FEATURES



SEH end suction centrifugal pump

Pump Body

A double volute design

Rotor back-pumping design, easy to maintain without affecting the pipeline;  

Adopt central support, installation form is APl610 OH2; Reduces the increase in the different axialities between the pump and the drive caused by high pressure (or high temperature) operation, thereby increasing the stability of operation and prolonging the service life of the equipment.

Impeller

Closed impeller, higher hydraulic efficiency;

Excellent hydraulic model and precision casting, making it efficient and energy-saving;

If necessary, the inducer wheel can be added to improve the necessary NPSH;

Shaft

Heavy load shaft, the shaft offset is minimized under maximum heavy load to ensure the good operation of the components on the shaft, the pump operation is more stable, the bearing and mechanical seal have a longer life, and the maintenance and repair costs are reduced.

Shaft Seal

Cartridge mechanical seals withstanding high pressures;

Bearing Body

Heavy load design with a large capacity oil chamber to ensure long-term reliable operation of the bearing

Use of high load cylindrical and thrust bearings, lubricated with dilute oil;

Coupling

Optionally configured with diaphragm coupling, column pin coupling, etc.;

Parts

Modular design, high degree of versatility, reduced spare parts inventory

Thickened wall thickness

in addition to meeting the strength and increasing the corrosion margin, prolonging the applicable life.

Flange

It can be manufactured according to GB、ANSI、DIN、JIS and other standards;
