Resistance Pump Spare Parts
Corrosion-resistant Polyurethane Spare Parts
Polyurethane is an extremely versatile elastomer with countless applications around the world. It can solve problems with performance characteristics that other materials cannot handle. Polyurethane elastomers are an erosion-resistant material that performs well in elastomer applications where "wear and tear" is a problem. Polyurethanes offer higher load carrying capacity, compression deformation and excellent resistance to grease, oil, oxygen and ozone.
We offer a wide range of polyurethane wet parts, impellers, throat bush, cover plate liner, frame plate liner etc.
Features
1. Wide range of hardness and elasticity
Polyurethane has higher impact resistance and resilience than plastic, and has very good recovery properties. It can still maintain good rubber elasticity and elongation under high hardness.
2. High load-bearing capacity
Polyurethane has high load-bearing capacity in both tension and compression, with higher tear strength and load-bearing capacity than ordinary rubber; It has impact strength and bending strength under high hardness.
3. Good wear resistance and impact resistance
For challenging applications with severe wear, polyurethane is an ideal solution even at low temperatures. It has high tear resistance and tensile properties.
4. Waterproof, oil and grease resistant
The material properties of polyurethane remain stable in water and oil (with minimal expansion) and can be used underwater for many years.
Material features
Polyurethane is suitable for fine to medium particle erosive slurry applications. Can withstand “erosion”.
