Explore the Main Products of Pumps Used in Water Treatment

Introduction:

Water pumps are integral equipment in water treatment, playing a vital role in transporting fluids by supplying energy to overcome flow resistance and maintaining a steady flow within equipment or pipelines. Additionally, during water treatment processes, chemical agents often need to be transferred from one tank to another, from a lower to a higher level. All these tasks are accomplished through the work of water pumps. Therefore, choosing pump products wisely and understanding the technological trends in water treatment pumps become crucial aspects of water treatment operations.

Sewage Pumps

Sewage pumps, consisting of pump body, pump cover, bearing box, impeller, shaft, among other parts, are primarily used for transporting fluids with suspended solids or fibers below 80°C. They are ideal for corrosive sewage with acidic, alkaline, or other corrosive properties. There are two main types of sewage pumps: regular electric motor sewage pumps and submersible sewage pumps.

Centrifugal Pumps

Centrifugal pumps, such as the S-type centrifugal pump and Sh-type centrifugal pump, are used to transport clear water fluids in water treatment processes, with a maximum temperature not exceeding 80°C. S-type centrifugal pumps are cost-effective with high efficiency, while Sh-type centrifugal pumps offer high reliability and long lifespan. The open design of centrifugal pumps ensures a balanced axial thrust during operation.

Reciprocating Pumps

Reciprocating pumps rely on the reciprocating motion of pistons (or plungers) in the pump cylinder to change the cylinder’s volume, achieving the suction or discharge of liquids. They include piston pumps, plunger pumps, and diaphragm pumps. Diaphragm pumps differ by having a membrane separating the working chamber and the cylinder body, contributing to the suction or discharge of liquids.

Corrosion-Resistant Centrifugal Pumps

These pumps, particularly single-stage single-suction cantilever-type corrosion-resistant pumps, are designed for conveying corrosive fluids without solid particles. They are commonly used in ion exchange processes for transporting H-water in water treatment. The flow components in contact with the conveyed medium are made of stainless steel or plastic.

Metering Pumps and Screw Pumps

In water treatment processes, metering pumps and screw pumps are widely applied.

  • Metering Pumps: These include piston-type and diaphragm-type pumps. They offer dynamic or static flow adjustment capabilities by adjusting the distance between the screw and eccentric shaft. J-type metering pumps find extensive use in accurately metering, adjustable dosages, and continuous delivery of media. In water treatment processes, they transport and dose both corrosive and non-corrosive agents without solid particles.
  • Screw Pumps: There are single-screw pumps, twin-screw pumps, and three-screw pumps. They are suitable for conveying various fluids, including neutral or corrosive, clean or abrasive, gaseous, or bubble-prone liquids, as well as high-viscosity or low-viscosity liquids containing fibers or solid particles. Screw pumps operate by using a rotating screw to create pressure, ensuring economic performance, high pressure, uniform flow, and high speed.

Conclusion

Understanding these main pump products is crucial for making informed decisions in water treatment. These pumps play a significant role in ensuring efficient fluid transportation and processing in various water treatment processes.
