Udor KAPPA 32 GR3/4 — 9.5 GPM (36 L/min) Diaphragm Pump

The KAPPA 32 GR3/4 packages the KAPPA 32’s 36.0 L/min (9.5 GPM) flow and 38 bar (560 PSI) pressure with a built-in gear reduction unit for a 3/4 inch petrol engine shaft rated 4–6.5 HP. The gearbox brings the engine’s output down to the pump’s 550 RPM operating speed, so there is no belt drive to tension or replace. At 28 lbs it suits a compact petrol-powered spray cart or trailer where a mains or battery supply is not practical.
