When you’re setting up a sprayer system or need precise liquid handling on your operation, this AR30 diaphragm pump delivers the reliable performance you need. With its 3/4 inch keyed shaft on one end and flange mount on the other, this pump gives you flexible installation options whether you’re connecting to a PTO, electric motor, or gas engine. The 9.5 GPM flow rate and 580 PSI pressure capability makes it ideal for medium-pressure applications where you need steady, consistent flow.

Built for Real Farm Work
This AR Pumps diaphragm pump is sized right for medium-scale operations where you need more capacity than a small pump but don’t require the expense of a high-volume unit. It’s commonly used on field sprayers, wash-down systems, and liquid fertilizer applicators. The diaphragm design means it’ll handle chemicals and fertilizers without the seal problems you get with centrifugal pumps.
Made to Last
AR Pumps has been in the business for decades, and this unit shows why. The twin diaphragm design provides smooth flow with less pulsation than single-diaphragm pumps, and the construction handles the vibration and temperature swings that come with farm use. The sealed bearings and quality materials mean this pump will keep working season after season.
Good to Know
The keyed shaft accepts standard pulleys or couplings, while the flange mount lets you bolt directly to gearboxes or motor mounts. Check your drive speed – this pump works at both 550 RPM and 3600 RPM, so you’ve got options for different power sources. A quick tip: prime the inlet line before starting to get the best performance right from the get-go.
