2/1.5B-AH Polyurethane Pump Parts
Polyurethane (also named PU) is an unique material that has the elasticity of rubber combined with the toughness and durability of metal. It permits the engineer to replace rubber, plastic and metal with the ultimate in abrasion resistance and physical properties. Polyurethane can reduce plant maintenance.
Polyurethane Slurry Pump Impeller (PUR and PU) is made by Polyurethane which is a polymer composed of a chain of organic units joined by urethane links. This impeller have better performance than natural rubber impeller for the slurry transportation.
Besides,we also have Polyurethane Cover Plate Liner,Frame Plate Liner,Throat Bush,Frame Plate Liner Insert etc.

Characteristics
The abrasion and tear resistance of Urethanes are much better than rubbers, while having higher load bearing capacity. Compared to plastics, urethanes have superior impact resistance, while having excellent wear properties and elastic memory. Besides, PU is more advance in weight reduction, noise abatement and wear resistance than metal parts.
However,Urethanes are unsuitable for temperatures exceeding 70ºC and for concentrated acids and alkalies,ketone,esters,chlorinated and nitro hydrocarbons.
