Product Description

A complete Udor Kappa 40 Pump / Motor / Gearbox / Regulator Assembly, expertly assembled by our mechanics and ready to drop into place on your spray rig. This package includes a Udor Kappa 40 Diaphragm Pump, a Honda 5.5 HP GX160QH Gas Engine, the Udor 5071.75 Gearbox and a Udor 6010.24 Regulator Pressure Relief Valve.

This Assembly is intended for our professional customers who prefer not to construct, or are unable to construct a pump motor combination on their own. When we ship this assembly we put oil in the Udor Pump but not in the Gearbox or Honda Engine, we do provide this oil and instructions in the box for your convenience. Just bolt down the Honda Engine, attach your hoses and you are ready to spray. We detach the regulator for shipping so that it is not damaged, it is only 2 bolts to reattach it to the pump.

This Honda 5.5 HP gas engine and Udor Kappa 40 Diaphragm Pump are recommended for agricultural and horticultural spraying applications. Capable of handling the pumping and spraying of a variety of fluids, including herbicides, pesticides, liquid fertilizers, abrasive materials, de-icing materials, and other hard-to-handle fluids.

The Optional Mounting Plate is an accessory for the pump-motor combos and includes bolts that allow you to attach your pump-motor combo to a trailer bed or spray rig.
