Slurry pump polyurethane spares are made by Polyurethane (PU for short), and they have a better performance than the natural rubber spares in the slurry transportation, especially in the tough conditions with corrosive and abrasive.

Compared with natural rubber material, PU material has these advantages:

Wide range of hardness- shore A 10 – shore D 64;

Excellent wear resistance with a longer work life;

Excellent hydrolysis resistance, oil, acid and alkali resistance;

Excellent flexibility, impact resistance and shock absorption;

Low friction coefficient

It is proved that the work life of PU is longer than Rubber materials for 3~5 times, which greatly reduces the replacement frequency and issues during the pumping.
