Yamada pumps are among the top manufactures of high quality diaphragm pneumatic pumps.

This is a 1-1/2" Yamada air operated dual diaphragm aluminum pump and we use these on hydraulic our asphalt sealcoating pneumatic skid sprayer systems.

If you're looking for a pump that can handle all-day for a single spray wand operator, the 1.5" pumps are a great way to go.  Pair it up with a compressor that can handle 18+ CFM and you'll have a great sealcoating machine for medium to large sized parking lot spraying.

This pump operates from 20-120 psi (1.4 - 8.4 bar) and pumps fluids with viscosity of up to 20,000 CPS and pumpable solids up to 1/4 in. (6.3 mm) in diameter.
