A FULL RANGE OF PRODUCT FEATURES



End-Suction Centrifugal Pump

Pump Body

Some high-head pump bodies feature a double volute design

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

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

Mechanical seal, optional cartridge type; Configurable double-end mechanical seals;

Bearing Body

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

optionally configured with maintenance-free sealing grease lubrication, grease lubrication, or rare lubrication;

Coupling

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

Parts

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

Material

A variety of special alloy material configuration to meet the transportation of various special media;

Flange

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