An AR403-SP Pump and Honda GX160 Gas Engine Assembly to handle the toughest spraying jobs all season long.

Product Description

UPDATE: Hypro 9910 series diaphragm pumps will now be labelled by their manufacturer prefix ‘AR’ which stands for Annovi Reverberi. The specifications and performance remain the exact same.

We have combined a high-performance Annovi Reverberi AR403-SP Diaphragm Pump with gearbox and regulator (AR403-GR3/4-GCI) and a Honda GX160 Gasoline Engine so your spraying system has everything it needs to handle the toughest spraying applications all season long.

Two versions of this assembly are available:

  • AR403-SP Diaphragm Pump and Honda GX160QH Gas Engine (Recoil Start) Assembly (Part # AR403-5.5HP)
  • AR403-SP Diaphragm Pump and Honda GX160QXE Gas Engine (Electric Start) Assembly (Part # AR403-5.5ELEC)

Mostly assembled, these pump-motor combinations are ideal for professional customers who do not have the time to construct their own. You will first require a professional sprayer tank with the proper plumbing. You will have to attach the regulator, bolt down the engine, and attach your spray hoses.

The Annovi Reverberi AR403-GR3/4-GCI Diaphragm Pump is equipped with three BlueFlex diaphragms for optimal performance when pumping and spraying a wide range of common agricultural chemicals. Some of these include herbicides, pesticides, insecticides, de-icing fluids, as well as some aggressive chemicals used in agricultural, horticultural, weed and pest control, and lawn/turf spraying.
