The Udor ZETA-140/C is a high-capacity, low-pressure positive-displacement diaphragm pump designed for PTO-driven spraying equipment. This pump replaces the Udor RO-130/C.

Its three-diaphragm design produces up to 36 GPM at 300 PSI, giving the ZETA-140/C the combination of flow and pressure required for larger agricultural sprayers, orchard and tree sprayers, commercial spray equipment and other demanding liquid-application systems. Maximum pump speed is 550 RPM.

The ZETA-140/C features an anodized aluminum pump body, plasticized aluminum heads, glass-filled nylon manifolds and stainless-steel liquid-handling components. A built-in pulsation dampener helps smooth pressure pulsations produced by the diaphragm pumping action.

Unlike the smaller ZETA pumps, the ZETA-140/C is configured primarily as a PTO-driven pump. It comes standard with a 1-3/8" male six-spline PTO shaft, making it suitable for installation on compatible tractor PTO-driven sprayers.

Performance Specifications

PTO Fitment

The ZETA-140/C is designed for PTO-driven equipment.

PTO Connection

• 1-3/8" male PTO shaft
