Collection: Agricultural Diaphragm Pumps

Shop Annovi Reverberi agricultural diaphragm pumps for boom sprayers, orchard and vineyard air-blast sprayers, turf and lawn-care rigs, and soft-wash chemical systems. AR's semi-hydraulic diaphragm pumps keep the spray liquid away from the crankcase, so they handle fertilizers, herbicides and other aggressive chemicals that would wear out a plunger pump.

Why buy from Pittsburgh Spray Equipment

• We help match flow (GPM), pressure (PSI) and drive (PTO, gearbox, hydraulic or engine) to your sprayer before you order.
• Matching AR control units, regulators, pressure gauges and spray guns are listed alongside the pumps.
• Financing available on larger sprayer builds.

How to choose an AR diaphragm pump

Low pressure (up to about 290 PSI / 20 bar) - boom sprayers and soft-wash systems where volume matters more than pressure.

Medium pressure (about 360-725 PSI / 25-50 bar) - orchard, vineyard and air-blast sprayers and spray-gun work.

High pressure (725 PSI / 50 bar and up) - long-range handgun spraying, tree spraying and turf work with long hose runs.

Drive - 540 RPM PTO pumps mount straight on the tractor shaft; gearbox (GR) versions let a 1,000 RPM PTO or engine drive the pump; GCI / hydraulic versions suit skid and truck units.

FAQ

Why use a diaphragm pump instead of a piston or plunger pump for spraying?
The chemical only touches the diaphragms, valves and pump heads, never the oil-bath crankcase, so abrasive or corrosive mixes don't destroy seals and the pump can run dry for short periods.

What do the BP and LFP suffixes mean?
In AR model names, BP pumps are the compact standard line and LFP pumps are the low-pulsation, higher-flow line. Check each listing's GPM, PSI and RPM rather than relying on the suffix alone.

Do I need a control unit with the pump?
Yes. Every diaphragm pump needs a pressure regulator / unloader (control unit) to set spraying pressure and bypass flow back to the tank. AR control units are matched to pump flow and pressure ranges.
