Wetted Parts

Wetted Parts of Pumps

Slurry pumps contain several wetted parts that are essential for operation, including the volute liner, throat bush, frame plate liner insert, and the impeller. The pump impeller is one of the most important parts of the slurry pump. It is located in the pump body on the shaft and connects with the motor to form a centrifugal force system. When the motor drives the impeller to rotate, the blades force fluid to rotate, increasing its pressure, potential energy, and kinetic energy. At the same time, under the force of inertia, fluid flows from the center to the edge of the impeller, out at a very high speed, and passes through the discharge pipeline to be transported. When an impeller is rotating, and in good condition, the slurry pump can easily meet output expectations. They are, however, highly prone to wear and require regular maintenance to ensure efficiency.

Construction from high-quality materials plays an important role in prolonging the service life of an impeller, and certain materials work best for an application. We use high chrome (A05, 27%) for abrasive slurry or slurry with sharp particles. For corrosive slurries with blunt particles, we recommend natural rubber. We also offer other materials, including A07, A09, A49, PU, and ceramic for different applications, and our cemented carbide and molded elastomer impellers are completely interchangeable.

Wetted parts, especially the pump impeller, are vulnerable, require regular attention, and will likely require frequent replacements in large volume operation. Because abrasive particles in the slurry can produce high-speed scour on the wetted parts of a pump, they are more prone to wear, resulting in an increased risk of damage due to friction and corrosion. If the correct materials are not selected for a production process, this can take place in mere days. For example, a volute liner can be scrapped in approximately ten days if an incorrect material is selected.

We are happy to consult with you to recommend the best material such as A05, A07, A49, Ceramic, etc for your application and supply you with qualified spares. All of our pump spares are interchangeable with Warman originals and have the same working life, but we offer a much lower price. We have most of these spares available in our inventory and can deliver within five days after receipt of your purchase order.
