Udor KAPPA 18 DC — 4.2 GPM (16 L/min) Diaphragm Pump

Rounding out the KAPPA DC line, the KAPPA 18 DC is the bare pump sold to replace or rebuild a KAPPA 18 12-Volt unit without buying a complete new sprayer. Turning at its rated 1450 RPM, it delivers 16.0 L/min (4.2 GPM) at up to 20 bar (275 PSI), noticeably more pressure than the assembled 12-volt kit since the figures are not limited by a motor’s amp draw. Weighing just 14 lbs, it fits the same mounting pattern as the original for a quick, low-cost swap.
