South Africa’s Real Water Crisis: Not Understanding What’s Needed

A serious multi-year drought in parts of South Africa’s Northern and Eastern Cape provinces has seen a number of small towns threatened by total water supply failures and livestock farmers facing financial ruin.

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.
