Berkeley Jet's stainless steel XB impeller is a fresh new design from the company that made jet drives famous. Produced using a lost wax precision casting method from high strength 17-4 stainless steel. Featuring a improved center entry cone from the shaft to the blades to reduce cavitation. This CNC machined impeller is factory balanced and has a wear ring surfaced machined at 7.225” to match a factory sized wear ring. Available in standard A and A2 cuts with other cuts available at additional cost.

Berkeley Original Equipment Standard Size Stainless Steel Wear Ring - I.D. Installed is 7.250-7.252

Each Berkeley wear ring is constructed from seamless stainless steel.  By using a seamless wear ring Berkeley can CNC machine these wear rings to exacting tolerances.  These wear rings are not stepped so that there is no water deflection to the impeller. The clearance between the wear ring and impeller should be 0.025 when installed. When replacing a wear ring on an existing impeller measure the diameter of the impeller and consider an undersize wear ring if needed.

Berkeley Original Equipment Shouldered Stainless Steel Wear Ring

The Berkeley stainless shouldered wear ring can be used as a blueprintingtool to tighten the pump clearances. The shoulder puts a tighter seal to thefront of the impeller and by shimming the impeller back it also creates atighter seal on the back of the impeller to the bowl as well. Keep in mind thatto use the shouldered wear ring you must also purchase a shim kit part 152-K4007 to set the correct end clearance (.030 / .040) between the shoulder and thefront edge of the impeller
