Tecomec RGB18 Gearbox

The Tecomec RGB 18 A is a helical reduction gearbox rated for engines up to 18 HP. Designed to bridge the gap between petrol or diesel engines and high-pressure plunger pumps, the RGB 18 A delivers a smooth 1:2.19 gear reduction through precision-cut helical gears. Its reversible crankcase allows flexible mounting in a wide range of frame configurations, and at just 4.7 kg it keeps overall machine weight to a minimum. A proven choice for powering pumps from Annovi Reverberi, Bertolini, Comet, Interpump, Hawk, and Udor.
