Udor KAPPA 43 — 10.5 GPM (40 L/min) Diaphragm Pump

The KAPPA 43 is the highest-flow direct-drive pump in the KAPPA range, moving 40.0 L/min (10.5 GPM) at up to 38 bar (560 PSI) from a 25 mm solid keyed shaft and mounting rail fitting. Running at 550 RPM, it suits larger boom sprayers and washdown setups where the smaller KAPPA 25 or 32 would fall short on volume. At 29 lbs it is still compact enough for a trailer or skid frame, and shares the same Desmopan diaphragm and anodised body construction as the rest of the family.
