The Water Pump Housing Spacer is used during pump assembly to control the axial position of the impeller on the shaft. It is placed between the pump housing and the impeller to create a controlled gap during installation. This spacer allows the impeller to be pressed onto the shaft gradually without making direct contact with the housing. During assembly, spacers guide the pressing depth so the impeller reaches the correct position.Attributes:• Supports proper pump configuration during maintenance work.• Assists in proper alignment before pump operation.• Prevents impeller over-pressing on the shaft.Applications: The Water Pump Housing Spacer is used during pump assembly between the pump housing and impeller to control impeller position while pressing it onto the shaft.
