WitrynaThe Purpose of the Wear Ring. The reason why Seadoo does a wear ring is to protect it from any major damage that might come from not having a wear ring. A wear ring is quite simple, it’s a thick piece of plastic that wraps around the impeller. The gap between the impeller and the wear ring is very tight because it needs to be in order to push ... Witryna1 cze 1997 · An alternative to trimming the impeller vanes is to remove a small portion of the volute tip by machining or filing to achieve an increase in gap "B". The volute tip should preferably be rounded (bull nosed) to further soften the hydraulic shock pulse. An increase in gap "B" of no more than 8% is recommended with this approach.
Witryna6 paź 2024 · As the impeller moves away from the stuffing box, whether through wear or operator settings, the resultant gap will at some point become too great for the pump out vanes to exert their full effect. Most pump experts agree a performance drop will start to occur when the gap begins to exceed 0.060 inches (1.5 mm).
