The Annovi Reverberi AR403-SP Diaphragm Pump is recommended for medium pressure spraying applications that require flow rates up to 10.7 gpm (40.5 lpm) and pressures up to 580 psi (40 bar).

This semi-hydraulic, three diaphragm pump with BlueFlex diaphragms features anodized aluminum liquid handling parts for pumping and spraying a wide range of general agricultural chemicals, including liquid fertilizers, pesticides, herbicides, insecticides, and other hard-to-handle fluids. With the ability to be combined with gas engines, electric motors, or hydraulic motors, the AR403-SP can serve as an extremely reliable sprayer pump for medium pressure treatments in applications involving agricultural spraying, turf spraying, lawn care, weed and pest control, de-icing, gardening, greenhouses, orchard and vineyard spraying, and more.

With the BlueFlex diaphragms, you will receive some of the best performing diaphragms available today, totally redefining how durable a diaphragm can be, even when used in tough operating conditions. BlueFlex diaphragms easily handle a wide range of general agricultural chemicals like herbicides, pesticides, and liquid fertilizers, as well as some aggressive and hard-to-handle liquids. BlueFlex diaphragms have a shape and thickness that have been carefully optimized to limit mechanical stresses during the working cycle of the pump, even in tough operating conditions.

A newly designed blocking system of the diaphragms helps avoid contract tearing of the diaphragms, even in heavy-duty conditions. The valves with a spherical sector profile offer lower flow resistance and improved volumetric efficiency.

** Every diaphragm pump requires the use of a pressure regulator, so the AR GIC40 Regulator (see 'Related Products') is recommended for this pump. If you plan on attaching this pump to a 5.5 hp gasoline engine with a 3/4" (19 mm) keyed shaft, order the Hypro 9910-KIT1640 Gearbox (see 'Related Products').

To adapt the AR403 Diaphragm Pump to a 1" (25 mm) solid shaft, order 9910-KIT2202. To adapt to a PTO shaft, order 9910-KIT2200 (male) or 9910-KIT1704 (female).
