Delavan pumps ideal for low-volume, moderate pressure applications

DELAVAN AG PUMPS, Inc., has introduced Series 4400 Roller Pumps for low-volume, moderate-pressure pumping in agricultural applications. The 4-roller pumps are available in 5/8-inch solid shaft or 1/2-inch hollow shaft models.

Shafts are constructed of 416 stainless steel with an extra-fine finish to minimize seal wear and are supported at both ends by heavy-duty sealed bearings. They can provide flow output to 6.5 gpm at 1,800 rpm (electric motor) or 9.2 gpm at 2,600 rpm (gas engine) at pressures to 150 psig and can handle fluid temperature to 140 F.

The pumps weigh 5 pounds and feature ultra-rollers for smooth, high performance and long-wear life. Rotors are constructed of a corrosion-resistant alloy. Close tolerance machining assures maximum flow and pressure and prolongs roller life.
