UD-ZETA-120-VA
The UDOR ZETA 120 is a high-volume, low-pressure diaphragm pump engineered to dominate the agricultural and turf spraying landscape. Delivering a massive 31.0 GPM at 300 PSI (20 Bar), this 3-cylinder workhorse provides the flow required for wide boom spraying and high-speed fertilizer application without sacrificing reliability.
What sets the ZETA 120 apart is its hybrid construction. It features an anodized aluminum crankcase for thermal efficiency, mated to plasticized aluminum heads and glass-filled nylon manifolds. This unique architecture gives you the structural strength of metal with a "poly-like" chemical shield, making it impervious to liquid nitrogen, fertilizers, and aggressive herbicides that rot standard cast pumps. Whether you are running a de-icing rig or a field sprayer, the ZETA 120 is built to outlast the season.
