WitrynaThe wear ring has two main purposes on a jet ski. The first is to seal the pressure leakage of water in the pump. To put it more simply, the wear ring ensures a tight fit around the impeller, which is the key to high pump pressure. The tighter the fit, the more power you have! That’s why manufacturers try to keep this gap as tight as possible. Witryna31 sie 2011 · Apr 28, 2011 #2 The max allowable clearance is 0.040". Anything more than that... you will have bad cavitation. A good impeller, and an OEM SeaDoo wear ring will have almost no clearance when new. Most of the time... if you have bad cavitation... it's coming from a leak in the carbon seal.

WitrynaWear rings are fitted at the close clearance location in the pump casing and usually at an opposing position on the impeller.
