【Product description】

S, SH single-stage double suction level in the open centrifugal pump for the delivery of water and physical and chemical substances similar to the water, the media maximum temperature of 80 ℃, the bearing body into the cooling water pressure, can transport 130 ℃ below the hot water The Change the sealing ring, sleeve and impeller material, can be transported with muddy muddy water.

S series of open pump shaft seal generally use soft packing seal, plus special requirements, but also modified mechanical seal, from the motor side to see the pump, S-pump for clockwise rotation, SH-type pump for counterclockwise rotation. S, SH pump diameter of less than 300mm (including 300mm) or motor power less than 100KW, can be equipped with a common base when ordering to be explained.
