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 L/min) 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
