Screw Pump Rotor (Coating Rotor)

The Screw Pump Rotor (Coating Rotor) is a core component of screw pumps, working in conjunction with the stator to facilitate fluid conveyance. This rotor features a specialized surface coating designed to significantly enhance wear resistance, corrosion resistance, and overall operational stability. It is particularly suitable for handling high-viscosity fluids, abrasive media, and liquids containing fine solid particles.

A variety of coating options are available—such as tungsten carbide, nickel alloy, or ceramic coatings—depending on the working environment. These coatings help extend service life and reduce maintenance requirements. Each rotor is precisely machined to ensure high concentricity and dimensional accuracy, contributing to optimal sealing performance and pump efficiency.

Widely used in chemical processing, pharmaceuticals, food production, and environmental industries, the Coating Rotor can be customized in terms of coating type, rotor dimensions, and compatibility with specific pump models to meet diverse application needs.

Our company can provide related pump parts such as pump shafts, shaft sleeves, thrust plates, rings, wear-resistant rings, rotors, and other related pump parts. It is mainly used in shielding pumps, centrifugal pumps, mud pumps, rotor pumps, etc.

The above pump parts support customers to draw up processing.

Material:

We can use specified metal materials to make related parts of such pumps, such as stainless steel, 304, 316/316L, Sitai alloy, etc.

All of our pump parts can meet all your pump transmission needs, and provide ceramic and tungsten carbide surface coating to apply to abrasion, corrosive, and high-temperature applications.
