Corrosion resistant stainless steel centrifugal pump

The corrosion-resistant stainless steel centrifugal pump castings are cast using lost foam casting, greatly improving the surface quality of the hydraulic components, ensuring that the size, shape, and surface smoothness meet the design requirements, and reducing the errors in hydraulic performance caused by casting.

Technical advantages:

1. Design optimal matching: By achieving optimal matching of the main hydraulic parameters related to the impeller and pump body, high pump efficiency and performance can be achieved.

2. Reduce efficiency loss: Through hydraulic and structural design, achieve a balance between disc friction loss, volume loss, and hydraulic loss of the pump, resulting in a lower total energy loss of the pump.

3. Low noise and smooth operation: The blade design selects a relatively large blade wrap angle and a smaller outlet placement angle, ensuring smooth and low-noise pump operation.

4. Wide efficient zone: Specially designed blades have a similar efficiency during cutting, even when the cutting amount exceeds the conventional allowable cutting amount, the efficiency changes very little, and the efficient zone is wide.

5. Hydraulic components adopt hydraulic design methods, which are efficient, stable, and have low cavitation allowances.

6. The castings are cast using lost foam casting, greatly improving the surface quality of hydraulic components, ensuring that the size, shape, and surface smoothness meet the design requirements, and reducing the errors in hydraulic performance caused by casting.

7. Most pump impellers are equipped with front and rear sealing rings, and a balance hole is provided on the rear cover plate of the impeller to balance the axial force acting on the rotor. The residual small amount of axial force is borne by the bearings, and the pump runs smoothly with minimal vibration.
