Comet APS41PGR Diaphragm Pump - Plastic Coated

The Comet APS41PGR Plastic Coated Diaphragm Pump includes a gearbox for attachment to a gasoline engine with a 3/4" shaft. Pressure regulator not included.

The special plastic coating on this internally-manifolded, three diaphragm Comet pump provides excellent resistance to corrosion when handling agricultural chemicals and some harsh chemicals. The pump heads, valve plugs, and discharge plate have this plastic coating for corrosion protection in common areas that are prone to be attacked. This plastic coating is an electrostatically dipped coating that penetrates the aluminum surface and cannot be chipped that easily in transport. 

With the ability to generate maximum pressures of 580 psi, the Comet APS41PGR is recommended for medium pressure spraying applications, including lawn and turf spraying, low-height tree spraying, agricultural spraying, pest control, insect control, and more. It is great for pumping and spraying agricultural chemicals, such as herbicides, pesticides, insecticides, liquid fertilizers, de-icing materials, as well as some harsh chemicals used for disinfecting, roof moss control, mosquito control, and more.

To help extend the life of the diaphragms, the Comet APS41PGR features 'Duraphragm' technology, which helps prevent the diaphragms from coming in contact with the chemical inlet. The inlet vacuum is spread across the entire surface of the diaphragm instead of focusing it in one smaller area, which is where most failures in the diaphragm occur.
