Udor ZETA 85 VAGR3/4 — 22 GPM (85 L/min) Diaphragm Pump

Stepping up the ZETA 40’s petrol platform, the ZETA 85 VAGR3/4 nearly doubles flow to 85 L/min (22.0 GPM) while holding the same 20 bar (300 PSI) pressure ceiling, all from the same compact 3/4 inch gear reduction drive for a 4–6.5 HP petrol engine. It is built for larger orchard and vineyard sprayers or broadacre boom rigs that have outgrown the ZETA 40’s output but still want a self-contained petrol unit rather than a tractor PTO pump.
