Polyurethane (usually abbreviated as PU) is a unique material that combines the elasticity of rubber with the toughness and durability of metal. It enables engineers to replace rubber, plastic and metal with extreme wear resistance and physical properties. Polyurethane can reduce factory maintenance.

Polyurethane has much better abrasion resistance and tear resistance than rubber, while providing higher load-bearing capacity. Compared with plastics, polyurethane has excellent impact resistance, while having excellent abrasion resistance and elastic memory. Moreover, PU is superior to metal parts in weight reduction, noise reduction and wear resistance.

Soft polyurethane is mainly a thermoplastic linear structure, which has better stability, chemical resistance, resilience and mechanical properties than PVC foaming materials, and has less compression deformation. Good heat insulation, sound insulation, earthquake resistance and anti-virus performance. Therefore, it is used as a packaging, sound insulation, and filter material. Rigid polyurethane plastic is light, sound insulation, superior thermal insulation, chemical resistance, good electrical performance, easy processing, low water absorption.

The impeller is the rotor and rotating part of the centrifugal pump. The front and rear shields have pump-out vanes to reduce recirculation and seal contamination. Hard metal and molded elastomer impellers are completely interchangeable. Casting in the impeller thread does not require inserts or nuts. It can also provide high efficiency and high lift design. It increases or decreases the pressure and flow of the fluid. When the slurry pump handles the solid mixture, the most worn component is the impeller. The impeller is the most important part of the pump. It is the core of the mud pump.

The service life of polyurethane impeller is 3~5 times longer than that of rubber material. Polyurethane liquid receiving parts include impeller, laryngeal mask, frame plate lining, cover plate lining, frame plate lining insert, etc. They are very easy to wear parts because they work underneath. Long-term effects of abrasive and corrosive mud. For the long service life of pump parts, polyurethane materials play an important role here.
