Udor KAPPA 18 12-Volt HP — 4.2 GPM (16 L/min) Diaphragm Pump

Built for jobs that need both flow and pressure, the KAPPA 18 12-Volt HP holds the same 16.0 L/min (4.2 GPM) output as the standard KAPPA 18 but more than doubles the pressure ceiling to 10 bar (150 PSI). It uses the heavy-duty 12-volt DC motor shared with the KAPPA 15 HP, drawing up to 35 A, and the added motor mass brings weight to 35 lbs. It remains a straightforward battery unit for quads, utes and trailers, just with headroom for tougher spot-spraying tasks.
