The Interpump Kit 102 Unloader Valve Service Kit is a comprehensive maintenance kit designed to restore and service the integrated unloader valve assembly found on Interpump Series 51 pumps and Series 60 pumps with a built-in unloader. The kit contains all the critical wear components required to refurbish the unloader valve, helping to maintain correct operating pressure, improve pressure regulation, and extend the service life of the pump. 

The service kit includes replacement guide bushes, control and spherical valves, valve seats, springs, anti-wear rings, O-rings, valve guides, and associated sealing components. These parts are manufactured to Interpump specifications, allowing worn or damaged unloader assemblies to be rebuilt without replacing the complete valve.

Regular replacement of these wear items can help prevent pressure fluctuations, unloader valve sticking, internal leakage, and premature component wear, ensuring reliable performance in professional pressure washing and cleaning equipment applications. Suitable for routine servicing, preventative maintenance, and repairs, the Kit 102 provides an economical solution for keeping Interpump pumps operating at peak efficiency.
