Product Overview
The sOW series single-stage double suction pump is a horizontal open volute centrifugal pump, mainly used for conveying clean water or liquids with physical and chemical properties similar to water with a temperature not exceeding 405 ° C. Suitable for conveying liquids in water plants, pump stations, power stations, air conditioning circulating water, heating hot water circulation, industrial water supply systems, fire protection systems, ships, oil refining industry (general liquids) and other occasions.

Hydraulic power
The optimized hydraulic model not only enables the pump to have excellent hydraulic performance, but also eliminates the problem of axial force (theoretically) that surrounds the operation of pumps, especially large pumps. The pump body, pump cover, and impeller are precision cast, and the smooth flow surface improves the anti cavitation performance and efficiency of the pump.
Seal
According to the conveying medium or user requirements, use packing seals or mechanical seals without being restricted by steering. For packing seals, there is sufficient space for replacing the packing.
Working conditions
1. The allowable working pressure is 2.5MPa; The pump inlet pressure+pump head is ≤ 2.5MPa. According to the maximum pressure that the pump casing can withstand, the materials of the pump body and pump cover are gray cast iron (1.6MPa), ductile iron (2.0MPa), and cast steel (2.5MPa). Please indicate the pressure bearing condition or material of the pump when ordering.
2. Medium: Water with a temperature ≤ 105 ℃ or other liquids with physical and chemical properties similar to water (solid particles ≤ 80mg/L).
Bearing
1. Sealed rolling bearings lubricated with grease are easy to maintain and have a long operating time.
2. Equipped with a constant oil level oil cup, it can also be lubricated with thin oil.
3. Imported (SKF, NSK, NTN) high-quality bearings are selected for smooth operation, low noise, and long service life.
Performance parameters
Compact structure and good stability This type of pump has a split structure with the pump casing, and both the inlet and outlet are located on the pump body. During maintenance, only the pump cover needs to be lifted out, and the rotor components can be removed for maintenance without disassembling the pipeline, which is very convenient.
The electric motor (driver) can be installed on the left or right end as needed, making it convenient for on-site installation. Structurally shortening the axial dimensions of rotor components results in better shaft rigidity and more stable and reliable operation. There is a pump body sealing ring, and the impeller sealing ring is an optional component. The sealing ring can be replaced after wear, reducing operation and maintenance costs.
