According to pump technical expert, Charlie Simpson, Vesconite wear rings should be considered for many of the horizontal split-case pumps that are operating in the harsh Australian mining and metallurgical environments.

Mr Simpson noted that the company’s wear rings are chemically inert in many cases.

Vesconite Bearings, the maker of the thermoplastic that is machined to make the wear rings, has tested its polymer’s chemical resistance to many mild acids, mild alkalis, organic chemicals, solvents, hydrocarbons, oils and fuels, and has a chemical resistance chart that shows resistance to many chemicals.

The polymer has demonstrated chemical resistance at 25°C to many common chemicals found in the mining sector, including sulphuric acid (10 per cent), nitric acid (10 per cent), petrol and diesel, and a host of other chemicals.
