Vesconite wear rings should be considered for many of the horizontal split-case pumps operating in the harsh South African mining and metallurgical environment.
This is according to pump bearing consultant Charlie Simpson, who notes 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 chemical resistance for many chemicals.
The polymer has demonstrated chemical resistance at 25°C to many common chemicals found in the mining sector, including sulphuric acid (10%), nitric acid (10%), petrol and diesel, among a host of other chemicals.
