Udor ZETA-P 42 VAGR3/4 — 10.5 GPM (42 L/min) Diaphragm Pump

The ZETA-P 42 VAGR3/4 puts the same corrosion-resistant polypropylene body as the ZETA-P 42 VA onto a petrol-ready platform, adding a gear reduction drive for a 3/4 inch shaft from a 4–6.5 HP engine. It matches the VA version’s 42 L/min (10.5 GPM) flow and 20 bar (300 PSI) pressure, at a slightly heavier 31.3 lbs due to the gearbox housing. It is the pick for standalone petrol-powered spraying of fertilisers, de-icing fluid or other chemicals that would attack a standard aluminium pump over time.
