Product Description

The Annovi Reverberi AR252-GR-GCI3/4 Diaphragm Pump includes a pressure regulator and a gearbox for attaching to a 5.5 HP gas engine with a 3/4" shaft.

This semi-hydraulic, two diaphragm pump is extremely dependable in the field for critical spraying jobs that require flow rates up to 6.5 gpm and pressures up to 362 psi. Its two diaphragm design and plastic-coated aluminum liquid handling parts enable this sprayer pump to be used for pumping and spraying many agricultural chemicals, such as herbicides, fungicides, insecticides, pesticides, liquid fertilizers, and other hard-to-handle fluids with ease. An excellent addition for small sprayers, the AR252GRGI Diaphragm Pump will perform up to professional standards for medium pressure treatments involving lawn care, turf spraying, agricultural spraying, weed control, pest control, de-icing, orchard and vineyard spraying, gardening, and much more.

The BlueFlex diaphragms included on the Annovi Reverberi AR 252GRGI Diaphragm Pump are made with some of the best performing diaphragm material available, establishing a new benchmark for diaphragm toughness, even under tough operating conditions. They are capable of not only handling general agricultural chemicals, but some of the more aggressive and hard-to-handle fluids as well. The shape and thickness of BlueFlex diaphragms have been carefully optimized to reduce mechanical stresses during the working cycle of the pump, even in tough operating conditions.
