Overview

SOW open volute double suction centrifugal pump 1. Trial working pressure is 2.5MPa; That is, 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 condition or material of the pump when placing an order. 2. Medium: Clear water at a temperature of 105 ℃ or other liquids with physical and chemical properties similar to clear water (solid particles 80mg/L).

SOW open volute double suctioncentrifugal pumpstructural characteristics

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.

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.
