Need a great air powered sealcoat pump?
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 1-1/2" air operated dual diaphragm (AOOD) pump is great for medium to large sealcoating setups where a 300+ gallon tank is used for all day use. 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: 666150-122-C, you get a 1.5" aluminum body (NPTF), aluminum manifold and aluminum seat material with the Buna-N ball and diaphragm material.
1.5" air powered sealcoating pumps are the industry standard for all-day-use, single operation sealcoaters who need a good flow and strong pump that will handle medium to large jobs with no problem. These pumps are perfect for medium and large asphalt lots, provided you have an adequate air-compressor supply. We typically recommend a minimum of a 10 gallon compressor that can average around 16 - 22 CFM.
The two biggest differences between the 1.5" and 2" pump, is the number of times the pump has to cycle to output the same amount of material. Also, while the 1.5" is almost enough to run two spray wands, we don't recommend it. If you need two guys spraying at the same time, we highly recommend stepping up-to the 2" pump and 30 gallon or larger compressor.
If you're a one-man sprayer in the market for a great contractor air-powered diaphragm pump that can be used all day, this ARO pump is a great place to start. Or, check out the Yamada 1.5" pump as a great alternative with similar specs.
