SY, DY and SDY series  pipeline oil centrifugal pumps are mainly used as the split case oil pipeline centrifugal pump for the refinery, chemical and petrochemical industries, and also as split case centrifugal pump for the power plant, steel mill, seawater desalination, fire control, oil-field water flooding and other systems.

• For a horizontal split case pump, it only needs to open the pump cover, instead of loosening the inlet and outlet pipeline of the pump, for overhaul;

• Without the shaft sleeve, the impeller is fixed on the shaft by a snap ring;

• Cartridge mechanical seals, easy to disassemble and assemble;

• It has a wear ring to extend the service life of the impeller and pump casing;

• The coupler is long enough to replace the mechanical seal and bearing without moving the pump and motor;

• Large flow-rate range, single pump with high head, and high anti-cavitation performance;

• For inter stage transition flow path, the internal flow path is adopted, which has high hydraulic efficiency and wide efficient range;

• Simple and reliable structure, and easy for maintenance.

• Structure type: BB1 or BB3

• Structural design: in compliance with API610

• Performance range:

• Flow rate (Q): ~8000m3/h
