The Remco RollMax R440RK Universal Repair Kit is designed to restore performance and extend the service life of compatible RollMax 4-roller pumps used in agricultural spraying, liquid transfer, and commercial chemical application systems. Built for preventative maintenance and fast field servicing, this rebuild kit includes the critical wear components needed to keep roller pumps operating efficiently and reliably.
The R440RK kit includes replacement max rollers, needle bearing, lip seals, O-ring, and pill key engineered for compatibility with Remco RollMax 4-roller pump assemblies including the R440C and R440SS series. Roller pumps naturally experience wear over time from friction, chemical exposure, and continuous operation, making routine maintenance essential for maintaining proper flow performance and pump efficiency.
One of the advantages of the RollMax platform is its simple serviceable design. Common wear components can be replaced quickly using basic hand tools, helping operators minimize downtime without replacing the complete pump assembly.
Whether servicing agricultural spraying equipment, transfer systems, engine-driven spray rigs, or commercial chemical application systems, the Remco R440RK Repair Kit helps operators rebuild worn pumps and return equipment to service quickly.
Keeping repair kits on hand during peak spraying season helps reduce downtime and maintain reliable spraying performance when equipment availability matters most.
