Remco RollMax R660C 6-Roller Pump - Cast Iron, CCW, 5/8" Shaft, 19.6 GPM

The Remco RollMax R660C is a high-volume professional-grade 6-roller pump engineered for demanding agricultural spraying, liquid transfer, and PTO-driven chemical application systems. Delivering up to 19.6 GPM and 150 PSI, the R660C is designed for operators requiring increased flow capacity, reliable field performance, and simple serviceability in demanding spraying environments.

Built with a rugged cast iron body, the R660C is designed for high-volume agricultural spraying applications where durability and throughput are critical. Its 6-roller design delivers significantly higher flow capacity than smaller 4-roller pump configurations, making it well suited for larger acreage coverage and higher-demand spray systems.

One of the key advantages of the RollMax platform is its Rebuild Ready design. The R660C can typically be serviced directly in the field using only basic hand tools without disconnecting plumbing or removing the pump from the drive shaft. This helps reduce downtime and simplify maintenance during peak spraying season.

The R660C utilizes a counter-clockwise (CCW) rotation configuration with a 5/8" shaft designed for PTO-driven spraying systems. Standard 3/4" FNPT ports allow easy integration into agricultural and industrial spray equipment.

For operators running high-volume PTO spraying systems, the Remco RollMax R660C delivers dependable commercial-duty performance with straightforward field serviceability.
