SH Series Double-Suction Mid-Opening Pump

SH Series Product Introduction

The Sh series and S series are single-stage, double-suction, horizontal split-case centrifugal pumps, suitable for conveying clean water and liquids that are non-corrosive (or slightly corrosive). The medium's maximum temperature is 80°C; after the bearing housing is supplied with cooling water, it can transport hot water below 130°C. By altering the manufacturing materials of the sealing ring, shaft sleeve, and impeller, it can convey muddy water containing silt; by changing the materials of the pump body and cover, it can increase the pump's inlet pressure, suitable for applications such as air conditioning and heating closed-loop systems. Copper impellers and copper sealing rings are used for transporting oil products.

The pump shaft seal is sealed with soft packing (graphite asbestos or carbon fiber packing). According to customer requirements, mechanical sealing can also be used. From the motor direction, the inlet of the Sh-type pump is on the left (counterclockwise rotation); the inlet of the S-type pump is on the right (clockwise rotation). The rotation direction of the pump can be changed according to customer requirements.

Manufacturing Materials: Pump body and cover – cast iron or ductile iron; impeller – cast iron, ductile iron, or cast copper; shaft – carbon steel or stainless steel.

Pumps with power ≤ 100kW come with a common base. For pumps with power > 100kW and diameter ≥ 350mm, a common base is supplied only upon customer request.

The significance of numbers in pump model names: e.g., 10Sh-9A. 10 -- The pump's inlet and outlet diameters are divided by 25 (the pump's diameter is 250), 19 -- The pump's specific speed is divided by 10, A -- The impeller has undergone the first cutting.

As for 600S-47, 600 - pump inlet and outlet diameter, 47 - pump design point head.
