Bian Angbu (Hangzhou) Mechanical Seal Co., LTD is specialized in designing, manufacturing and selling mechanical seals for Shanghai Kaiquan KQSN single stage double suction centrifugal pump.

KQSN mechanical seal is a multi-spring single end mechanical seal, the sealing surface is made of high-quality alloy, the substrate material can be selected as SUS304, SUS316L and so on.

The structure has the advantages of resistance to blockage, abrasion and corrosion, and the service life is more than twice that of the ordinary mechanical seal. Single end face, multi - spring, sealing face

The force is even. When used, has nothing to do with the handedness, conforms to ISO3069, DIN24960 and GB6556 standards, strong versatility. To better meet customer needs

To, the pump type as long as the pump model can be quoted, all organic seals are in stock, pump shaft, impeller, coupling and other accessories can be matched.
