4/3 AH Polyurethane Slurry Pump is popular in pumping fine aggregates. The construction aggregate industry transports slurry in various forms, from fine sand to coarse aggregate. Fine particle sand can be extremely abrasive and often rapidly wear down a slurry pump. The properties of coarse aggregates that can affect the performance of the pump are size, shape and surface texture, and gradation of particle sizes, with fine materials developing excessive friction in
the pipeline. Polyurethane slurry pump has been used for almost a century to protect plant and equipment from wear, and has retained its position as the preferred wear material for the pumping and separation of fine particle slurries. As the particles hit the surface, the polyurethane deforms, absorbing the kinetic energy of the particle. The resilient nature of the polyurethane returns most of this energy to the particle, causing it to rebound with little or no
wear. Slurry Pump Polyurethane impellers have a longer life, which reduces the frequency of replacing them. And because the material is smooth, there is little chance that the slurry will stick to the impeller and clog the pump.
Polyurethane Slurry Pump Spare Parts are made by the material of a polymer composed of organic units joined by carbamate (urethane) links, so the work life of Polyurethane slurry pump parts is longer than Rubber materials for 3~5 times, Slurry Pump Polyurethane Spare Parts include Impeller, Throat bush, Frame plate liner, Cover plate liner, Frame plate liner insert etc. They are very easily worn-out components because they work under longtime impact of abrasive and
corrosive slurries. For the long service life of pump parts, Polyurethane material plays an important role here.
