Udor ZETA-P 42 MI1 — 10.5 GPM (42 L/min) Diaphragm Pump

The ZETA-P 42 MI1 is built to bolt straight onto a hydraulic motor, using a 2-bolt A-flange with a 1 inch hollow shaft instead of a keyed drive, so the motor’s own output shaft passes through the pump rather than coupling via a separate key and pulley. That makes it a natural fit for skid-steer, trailer or self-contained hydraulic power packs, still delivering 42 L/min (10.5 GPM) at up to 20 bar (300 PSI). Its polypropylene body adds resistance to fertiliser, de-icing fluid and other aggressive chemicals.
