Compared with other pumps of the same type, the S series horizontal split case pump has the characteristics of long life, high efficiency, reasonable structure, low operating cost, easy installation and maintenance, etc. It is ideal for fire protection, airborne, chemical, water treatment and other industries.

Pump Body

The design pressure of the pump body is 1.6MPa and 2.0MPa. In order to meet the different requirements of users around the world, the corresponding pump body inlet and outlet flanges can be selected according to ANSI, PN and JIS standards. The inlet and outlet flanges of the pump body are located in the lower pump body, so that the rotor can be taken out without disassembling the system piping, which is convenient for maintenance. Some pumps are designed with dual flow channels to reduce radial forces, thereby extending the life of machine seals and bearings.


The hydraulic design of the impeller uses advanced CFD technology, thus improving the hydraulic efficiency of the S pump. Dynamically balance the impeller to ensure smooth operation of the S pump.


The shaft diameter is thicker and the bearing spacing is shorter, which reduces the shaft deflection and extends the life of the mechanical seal and bearing.

Shaft Sleeve

For all S pumps, a variety of different materials can be used for the shaft sleeve to prevent the shaft from corrosion and wear, and the shaft sleeve can be replaced.

Wear Ring

A replaceable wear ring is used between the pump body and the impeller to prevent wear on the pump body and the impeller. It is easy to replace and has low maintenance costs, while ensuring operating clearance and high working efficiency.

Filler Body

The unique packing body design can use either packing or mechanical seal, and the sealing device can be replaced without removing the pump cover.


The unique bearing body design allows the bearing to be lubricated with grease or thin oil. The design life of the bearing is more than 100,000 hours. Double-row thrust bearings and closed bearings can also be used.


According to the actual needs of users, the materials of S series horizontal split case pumps can be copper, cast iron, ductile iron, 316 stainless steel, 416 stainless steel, two-way steel, Hastelloy, Monel alloy, titanium alloy and alloy 20.


There are two installation methods for S-type pumps: horizontal installation and vertical installation. Vertical installation can reduce the floor space.
