SOW single-stage double-suction volute split case centrifugal pump

SOW single-stage double-suction volute split case centrifugal pump--Product overview

The optimized hydraulic model not only makes the pump have excellent hydraulic performance, but also has no axial force (theoretically), which is a difficult problem that circumvents the operation of water pumps, especially large-scale water pumps. The pump body, pump cover and impeller of SOW and SOL single-stage double-suction centrifugal pumps are precision-casted, and the flow surface is smooth, which improves the anti-cavitation performance and efficiency of the pump.

SOW single-stage double-suction volute split case centrifugal pump--Product features

1. SOW type single-stage double-suction center-open volute centrifugal pump has compact structure, beautiful appearance, good stability and easy installation.

2. The SOW type single-stage double-suction center-open volute centrifugal pump runs smoothly. The optimized double-suction impeller reduces the axial force to a minimum. It has a blade shape with excellent hydraulic performance and is precision casted. The pump casing The inner surface and the surface of the impeller are extremely smooth, with remarkable anti-cavitation performance and high efficiency.

3. The pump housing is a double volute structure, which greatly reduces the radial force, reduces the bearing force, and prolongs the service life of the bearing.

4. The bearings are selected from SKF and NSK bearings to ensure stable operation, low noise and long service life.

5. The shaft seal can be BURGMANN mechanical seal or packing seal. It can guarantee 8000 hours of operation without leakage.

6. After changing the material, it can transport the medium with a temperature of 150℃ and a certain degree of corrosion.

SOW single-stage double-suction volute split case centrifugal pump--Model significance

SOW single-stage double-suction volute split case centrifugal pump--Work condition

1. The trial working pressure is 2.5MPa; that is, the inlet pressure of the pump and the pump lift are less than or equal to 2.5MPa. According to the maximum pressure of the pump casing, the pump body and pump cover are made of gray cast iron (1.6MPa), ductile iron (2.0MPa), and cast steel (2.5MPa). Please indicate the pressure or material of the pump when ordering.

2. Medium: Clear water with temperature ≤105℃ or other liquids with physical and chemical properties similar to clear water (solid particles ≤80mg/L).
