Agricultural Roller Pumps

8800 Diamond Series roller pumps have bodies and endplates made of an alloy that resists agricultural chemicals and herbicides 10 times longer than cast iron.

The eight-roller pumps have flows up to 24 gpm and handle fluid temperatures to 140°F. Shafts of 416 stainless steel with heavy-duty sealed bearings supporting both ends have extra-fine finishes to minimize seal wear. Close tolerance machining on the corrosion-resistant rotors assures maximum flow and pressure, and prolongs roller life. Available options include PTO adapters and reverse rotation. Standard rotation is counterclockwise, with clockwise optional.
