525 Gallon Asphalt Sealcoating System - Hand Agitated - Accessories - Yamada

Our 525-gallon asphalt sealing machine delivers exceptional performance and value at an affordable price—without sacrificing quality. Designed for commercial-grade sealing jobs, this robust system includes many premium features found on more expensive models.

Built with a heavy-duty 1/4" thick polyethylene tank, this unit includes integrated manual tank agitation for reliable mix consistency. It's the larger version of our popular 325-gallon sealcoat system, ideal for professionals who require greater capacity.

The tank is equipped with a 1-1/4" solid steel drive shaft, supported by flange bearings and grease zerks at both ends. The air system features a Honda Puma 8-gallon manual-start compressor, capable of producing up to 150 PSI at 13.8 CFM. It pairs with a 1" Yamada dual diaphragm pump that operates without the need for lubrication.

A deluxe 3/4" aluminum spray wand with a 6-foot reach is included, along with 100 feet of 250 PSI-rated spray hose and an 80/40 spray tip. The system also comes with a .06 mesh strainer basket for added protection.

For added convenience, a manual Cox hose reel is mounted 48 inches from the bottom of the skid, eliminating the need to bend down when reeling in the hose. The tank includes a standard 16" lid, with optional upgrades available such as a poly hinged lid or a 22" square steel double manway—please inquire for details.

Perfect for asphalt contractors looking to expand their capabilities, this machine offers durability, efficiency, and convenience in one powerful package.
