Product Description

Hypro 4001 Cast Iron, Ni-Resist or Silver Series 4 Roller Pump

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 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. Rotation for the 4001 series is clockwise for easy adaption to electric motors and gas engines. Pumps are available in reverse rotation.

The 4001 series, 4 roller, pump achieves up to 9.1 gpm  (34.4 lpm)  and 150 psi (10.3 bar).  The series includes models 4001C, 4001N, and 4001XL.

Housing and Rotor Material Options

♦ Cast Iron housing and rotor are intended for use in common agricultural spraying applications – compatible with most insect, pest, brush and weed control chemicals. Cast Iron pumps lasted to 140 hours before failure.
♦ Ni-Resist housing and rotor provide improved corrosion resistance over cast iron models – compatible with all of the above, PLUS fumigants, powdered and liquid fertilizers. Ni-Resist pumps lasted to 332 hours before failure.
♦ Silver Series XL housing and rotor provide the best corrosion resistance and are ready for use with Roundup® – compatible with all of the above, PLUS glyphosates and acids. Silver Series XL pumps ran over 1000 hours and still met new pump specs!
