“When this customer started experiencing gland sealing arrangement problems with an existing pump, we offered them a trial replacement with one of our new technology SLR pumps to improve both the sealing arrangement and the overall performance,” said Rui Gomes, product manager for slurry pumps at Weir Minerals Africa. “The maintenance and short wear life of the existing pump parts were also an ongoing problem. The existing unit was leaking while in operation, which, in turn, caused the shaft sleeves to fail, resulting in regular packing change-outs.”
The Warman 75 SLR pump has proved to be the solution to these problems. This pump is fitted with an expeller that seals the gland without any leakage while in operation and does not require any external flushing water, Gomes said.
