Product Description

The Udor Kappa-55 Diaphragm Pump is internally manifolded with anodized aluminum construction. It features anodized aluminum and stainless steel liquid handling parts, as well as 3 long-lasting Desmopan diaphragms, ensuring the pump can handle use with many common, general use agricultural chemicals, such as pesticides, herbicides, liquid fertilizers, de-icing materials, and other hard-to-handle fluids.

As a result, this three-diaphragm, medium pressure Udor pump can handle the toughest spraying applications for horticultural, agricultural, and lawn care purposes, including: tree spraying, turf spraying, weed control, pest control, insect control, fluid transfer, hydrostatic testing, concrete curing compound, and more.

The Udor Kappa-55 is equipped with a universal drive face, built-in pulsation dampener, and a control unit with adjustable pressure regulator, manual dump lever, and pressure gauge.
