Airport Need a great sealcoating pump for spraying with a single wand? 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.
The Iwaki Air 1" air-operated dual diaphragm (AODD) pump is great for small sealcoating setups where a smaller tank, smaller compressor, and a smaller footprint are needed. We offer the Iwaki Air pumps as an alternative to the comparable Yamada pumps that come standard on our sealcoating spray systems.
Designed and made in Japan for over 50 years by the well-known YTS Pumps, Iwaki Air is the brand of YTS Pumps used to identify their air-operated pumps.
With the part number: TC-X253AN-NPT, 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 huge jobs. These pumps are perfect for driveways and small parking lots however we recommend stepping up to the 1.5" Iwaki Air 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.
For the most part, you'll want an air compressor that can handle between 15 - 20 CFM in order to get you between 6-9 GPM @ 85-90 PSI input. This is plenty of flow considering most guys using a 1" pump will run with the 80/40 or 80/50 tip which cuts your output flow down to 4.0 GPM or 5.0 GPM respectively.
