Udor KAPPA 25 — 7 GPM (26.5 L/min) Diaphragm Pump

The KAPPA 25 is a direct-drive diaphragm pump built around a 25 mm solid keyed shaft and mounting rails, so it bolts straight onto a petrol engine, electric motor or gearbox output without any adapter. Running at 550 RPM it delivers 26.5 L/min (7.0 GPM) at up to 24 bar (350 PSI), enough for small boom sprayers, misting rigs and general washdown work. At 18 lbs it is light enough to mount on a compact frame, while the anodised body and Desmopan diaphragm keep running costs low.
