Comet APS51 and Honda 5.5 HP Engine Assembly

We are offering two versions of these Comet APS51 Diaphragm Pump and Honda GX160 Engine assemblies for all your lawn spraying and agricultural spraying needs:

• Comet APS51 assembled with Honda GX160QH Gas Engine with Recoil Start (APS51-5.5HP)
• Comet APS51 assembled with Honda GX160QXE Gas Engine with Electric Start (APS51-5.5ELEC)

Both assemblies include the pressure regulator and gearbox for attaching the pump to the engine with a 3/4" shaft. For reference purposes, the pump with the regulator and gearbox alone is referred to as the Comet APS51-GR5.

The pump-motor assemblies have been constructed by our expert mechanics for those customers who cannot or do not have the time to construct their own. The assemblies come ready to drop right into place on your spray rig. You just require a professional sprayer tank and the proper plumbing. Some assembly is required, as we do not attach the regulator to avoid any unnecessary damages during shipping. The Honda gas engine needs to be bolted down, hoses need to be attached, and you are ready to spray. Oil is included ; however it is not placed in the gearbox or Honda engine.

You can use both versions of these Comet pump and Honda engine combos to handle many professional spraying applications for lawn care, industrial, horticultural, or agricultural applications. It also can handle some low-height tree spraying under 40'.

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.
