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 SilverCast™ body and rotor, and 416 stainless steel shaft, sealed factory-lubricated ball bearings, and cartridge-type lip seals of Viton or Buna-N. Super Rollers, which feature the life of polypropylene and the chemical resistance of nylon, are also standard. Standard rotation for all models is counter-clockwise for easy tractor PTO drive. Reverse rotation pumps are available.

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