roller pumps are designed for agricultural and industrial spraying
and transfer of a variety 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 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.
