South Africa – A golf course irrigation company that supplies many of South Africa’s golf courses had historically used multiple-stage canister pumps with neck ring casings with phenolic wear rings.
The phenolic wear rings were discovered to not be nearly wear-resistant enough to cope with the acidity levels and debris found in the storm water run-off and waste water that many South African golf courses are now irrigating with in line with global norms.
Vesconite Bearings’ differently-sized prototype wear rings were tested for a year, and the wear rings showed no evidence of needing to be replaced.
