The advantages of a rubber lined pump for wet sand applications
Mark Doyle, Global Product Manager for Linatex® Rubber, looks at the process of pumping fine aggregates and explains why rubber is the most suitable wear material for this application. 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…
