The KAPPA 55 VAGR1 fits a gear reduction box for a 1 inch petrol engine shaft onto the KAPPA 55’s VA mounting face, matching it to larger 8–20 HP engines than the standard 3/4 inch GR options in the range. The gearing brings that bigger engine down to the pump’s 550 RPM operating speed, still delivering the full 57.0 L/min (15.0 GPM) flow at up to 38 bar (560 PSI). It suits contractors and larger sprayer builds that need serious petrol power behind a diaphragm pump.
