Udor ZETA 120 VAGR3/4 — 31 GPM (116 L/min) Diaphragm Pump

At 116 L/min (31.0 GPM), the ZETA 120 VAGR3/4 is one of the highest-flow pumps in the petrol-driven ZETA line, though its 13.8 bar (200 PSI) pressure ceiling is lower than the smaller ZETA 40 and 85, trading pressure for sheer volume. It still uses the familiar 3/4 inch gear reduction drive for a 4–6.5 HP petrol engine, and at 55 lbs it is noticeably heavier than its siblings, reflecting the larger pumping elements needed to move that much liquid per minute.
