3-Frame Piston Pump

The CAT Pumps 280 is 3-Frame pump with Uniflow engineering that features a mechanically actuated inlet valve providing a continuous forward fluid flow and strong suction for efficient operation. It provides a flow rate of 3 GPM and endures a maximum pressure of 1000 PSI. Features NBR seals for chemical resistance. Cups and pistons are lubricated and cooled by the pumped liquid to increase the life of these components and the seals.
