SLOW type double-stage double-suction middle-opening volute centrifugal pump is specially designed and manufactured by our company to meet the needs of iron and steel plants, power plants, pumping stations, etc., and combines the advanced design experience of two-stage middle-opening pumps at home and abroad. It is manufactured by special machine tools. The conveying medium of this product is water and liquid similar to water, and the liquid temperature is-10℃-80℃.

Product Features

1. The water inlet and outlet are all on the pump body, so it is only necessary to lift the pump cover during maintenance, which greatly facilitates maintenance;

2. The impeller adopts the first-stage double suction and the second-stage single suction, which improves the cavitation resistance of the pump and reduces the axial size of the pump;

3. The rotating speed is 1480 r/min; Avoiding the vibration easily caused by high rotating speed; 4. Compared with a single-stage pump, it has the same performance, smaller impeller diameter and stable operation;

5. The water pressure chamber adopts double volute design to reduce radial force;

6, The use of rolling bearings, grease or rare lubrication, easy axial maintenance;

7. Adopt international advanced fluid mechanics software for design, three-dimensional software modeling and finite element software for strength check to ensure the efficient, stable and reliable operation of the pump;

8, all adopt mechanical seal, 8000 hours without leakage, packing seal can be customized according to customer requirements;

9. The pump rotates clockwise and can rotate counterclockwise according to user's requirements;

10. This product has applied for a national patent (patent number: ZL200520046059.0).
