The Remco 6-Roller Cast-Iron Pump Kit delivers powerful, consistent performance with a maximum flow rate of 19.6 GPM and up to 150 PSI of pressure. Designed for durability and efficiency, this pump features a 6-roller positive displacement design for improved priming and flow, housed in a rugged cast iron body that stands up to tough chemical applications. With a maximum operating speed of 1000 RPM, and 3/4" NPT inlet and outlet ports, it handles a wide range of liquids including herbicides, pesticides, fertilizers, water, and glyphosate. With the included 5/8" x 1-3/8" Multi-Speed die-cast quick coupler, you can directly couple to a tractor's PTO and run the pump at 540 or 1000 RPM with ease. The torque arm and chain kit prevent pump rotation, ensuring your roller pump remains secure and stable during operation. Ideal for crop spraying, pest control, washdown, and fluid transfer. For Professional Grade performance and durability, the Remco RollMax 6 Roller Pump Kit is built to work as hard as you do season after season. All RollMax Roller Pumps are Rebuild Ready, saving you time and money during the critical spray season. When worn rollers need to be replaced, simply loosen the 4 end plate bolts and carefully remove the end plate to inspect rollers. Then, using a RollMax repair kit, install new Max-Rollers, reinstall the endplate, and your RollMax pump is rebuilt and ready to spray.Package Contents: 1- RollMax Cast Iron 6 Roller Pump (R660C), 1 - 5/8" x 1-3/8" Multi-Speed Coupler, 1 - Torque arm with chain
