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 theultimate in abrasion resistance andphysicalproperties. Polyurethanecanreduce plant maintenance.

Polyurethane slurry pump impeller (PUR and PU) is made by Polyurethane which is a polymer composedofachain oforganic units joined by urethane links. Thisimpellerhavebetterperformance than natural rubber impeller for the slurry transportation.

Besides, we also have Polyurethane CoverPlate 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 bearingcapacity. Compared to plastics, urethaneshave superiorimpactresistance, 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 70℃ and for concentrated acids and alkalies, ketone, esters, chlorinated and nitro hydrocarbons.
