Need a great sealcoating pump for spraying with a single wand?
ARO pumps, a brand owned by Ingersoll Rand, have been known over the last 85 years to be a fantastic pump designer and manufacturer.
This 1" air operated dual diaphragm (AOOD) pump is great for small sealcoating setups where a smaller tank, smaller compressor and smaller footprint are needed. We offer the ARO pumps as an alternative to the comparable Japanese made Yamada pumps that come standard on our the sealcoating spray systems.
Where the ARO pumps mostly differ from the Yamada, is in the 5-year limited warranty offered on the ARO Pro pumps, compared to the 1-year limited warranty offered by Yamada. In addition to the warranty, the ARO Pro pumps are close in spec but slightly less than the Yamada. Check out the comparison table near the bottom of the page.
With the part number: 666100-122-C, you get a 1" aluminum body (NPTF), aluminum manifold and aluminum seat material with the Buna-N ball and diaphragm material.
1" pumps are perfect for single operation sealcoaters who need a good flow and strong pump, but aren't out there running their sealcoating rig on large jobs. These pumps are perfect for driveways and small parking lots however we recommend stepping up to the 1.5" ARO Pro pump if you plan on doing medium to large parking lots.
The biggest difference between the 1" and larger pumps, is the number of times the pump has to cycle to output the same amount of material. This is why we only recommend the 1" as a single wand unit because it can't handle larger material requirements.
So, if you're in the market for a great beginner diaphragm pump that won't break your budget and you won't be doing medium or big jobs, this is a great pump to start out with.
