Product Line Information

The basic model features a ribbed cast iron casing and rigid headplates, carburized and ground alloy steel spur timing gears secured to steel shafts with a taper mounting and locknut, and ductile iron impellers.

Oversized anti-friction bearings are used, with a cylindrical roller bearing at the drive shaft to withstand V-belt pull. At maximum load and speed our extra capacity cylindrical roller drive shaft bearing has 2.5 to 3 times longer bearing life than the competitive units using ball bearings.

Detachable rugged steel mounting feet permit easy in-field adaptability to either vertical or horizontal installation requirements.

The ROOTS-FLO is splash lubricated from oversized oil reservoirs.

Main air seals are piston ring type for minimal leakage. Bearing and drive shaft oil seals are Viton lip.

Warranty: Twelve months of operation or eighteen months from date of original purchase, whichever occurs first..
