The Water Spray Pump Impeller Shim Kit adjusts the clearance of the impeller shaft in a water spray pump by filling the space between the impeller and the pump housing. By fine-tuning the clearance, the shim helps achieve optimal alignment between the impeller and the pump housing, maximizing efficiency. This kit consists of 5 shims of varying thickness for effective adjustment of the impeller shaft in the water pump housing.Attributes:• Helps minimize wear and friction between the impeller and the pump housing• Manufactured to precise specifications and is built for durability and reliabilityApplications:The Water Spray Pump Impeller Shim Kit provides a set of replacement shims for fine-tuning the clearance between the impeller shaft and housing in a water spray pump.
