Hypro roller pumps are designed for agricultural and industrial spraying and transfer of a variety of fluids. These include insecticides, herbicides, emulsives, aromatic solvents, liquid fertilizers and many other liquids. The economical rotary-action roller principle requires no check valves while providing positive displacement characteristics with less friction and lower starting torque than other pumps. Construction features include a cast-iron, Ni-Resist or the new SilverCast™ body and Super Rotor, 416 stainless steel shaft, sealed factory-lubricated ball bearings, cartridge-type lip seals of Viton, Buna-N or leather, and versatile Super Rollers. (Super Rollers feature the life of polypropylene and the chemical resistance of nylon.) Rotation for all models is counterclockwise for easy tractor PTO drive, except models 4001 and 4101 which are clockwise. Pumps are available in reverse rotation.

This 7 – roller pump achieves up to 22.1 gpm  (83.6 lpm)  and 200 psi (13.8 bar).  The series includes models 7700C (Item # 75417), 7700N (Item # 75416), and 7700XL.
