Product Description

Here we have the ultimate pump-engine assembly for all of your professional spraying needs. The Udor Kappa 40 Diaphragm Pump, which includes a 6010.24 Pressure Regulator and 5027.75 Gearbox, comes coupled to a Honda GX160QH 5.5 HP Gas Engine.

This pump-engine combo is expertly assembled by our skilled mechanics for professionals who cannot, or just prefer not to, set up their own pump-engine combos. A real time saver for any professional, it's ready to drop right into place on your spray rig (you will require a professional sprayer tank and proper plumbing beforehand).

Some operations that this Udor Kappa 40 Pump and Honda GX160QH Engine Assembly are suited for include lawn care, agricultural applications, and low height tree spraying under 40'. It can handle the pumping and spraying of fertilizers, herbicides, pesticides, and much more. When the unit ships, you will notice oil is put in the Udor Kappa 40 Pump but not in the gearbox or Honda engine. However, the oil for the gearbox and Honda engine are included, as well as instructions.

All that is required of you is to bolt down the Honda engine, attach your hoses, and you can begin spraying. The pressure regulator comes detached and not connected to the pump in order to avoid potential damages caused during the shipping process.
