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

The KAPPA 18 12-Volt is the highest-flow member of Udor’s standard battery-powered KAPPA range, moving 16.0 L/min (4.2 GPM) at up to 5 bar (70 PSI). That low-pressure, high-volume balance suits larger spot sprayers and small booms where covering ground matters more than jet distance. A 12-volt DC motor drawing up to 28 A keeps it compatible with the same vehicle wiring as its smaller siblings, and the familiar anodised aluminium body and Desmopan diaphragm keep servicing simple and parts interchangeable across the KAPPA line.
