High Volume. Chemical Resilience. The Ag Spray Standard.

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.

Why Professionals Choose the ZETA 120

Plasticized Aluminum Heads: The aluminum heads are bonded with a thick polymer coating, isolating the metal from the fluid path. This prevents internal corrosion and "head rot" common with liquid fertilizers.

Glass-Filled Nylon Manifolds: The external manifolds are constructed from reinforced nylon, offering superior chemical inertness and easy modular replacement in the event of freeze damage.

GREENTECH Diaphragm Technology: Comes standard with UDOR's advanced Greentech diaphragms, which resist deformation and chemical attack far better than traditional nitrile rubber.

Triplex Design with Pulsation Dampener: The 3-cylinder configuration combined with a standard pulsation dampener ensures smooth, ripple-free flow essential for consistent application rates across spray booms.

Stainless Steel Valves: High-efficiency spherical check valves are made from stainless steel to resist pitting and wear from abrasive wettable powders.

Ideal Applications

The ZETA 120 is engineered for high-flow versatility across multiple sectors:

Agricultural Boom Spraying: The 31 GPM flow rate supports large booms for row crops, ensuring even coverage of pesticides and fungicides.

Liquid Fertilizer Application: Plasticized heads and nylon manifolds resist the corrosive effects of nitrogen and phosphorus fertilizers that destroy cast iron pumps.

Aircraft De-Icing: Capable of handling viscous glycol fluids and suspended solids found in de-icing and anti-icing operations.

Turf & Lawn Care: Quiet, low-RPM operation is perfect for golf course maintenance and residential hydro-seeding or drenching.

⚠️ APPLICATION NOTE: While the ZETA 120 offers excellent chemical resistance, it uses Nylon and Plasticized Aluminum components. For dedicated Soft Wash applications using high concentrations of Sodium Hypochlorite (Bleach) daily, we recommend the UDOR ZETA-PP (Polypropylene) series for maximum longevity.
