This is a light weight Yamada Aluminum "Air Operated Dual Diaphragm" Pneumatic Pump that is also very compact and can be used for portable sealcoat systems as well as more permanent installations such as our Asphalt Sealing Machine series of Sealcoat Spray Systems.

This Yamada dual diaphragm pump is air operated and requires an external air source and will deliver approximately 90 PSI for most sealers.

This 1" air operated dual diaphragm (AOOD) pneumatic Pump is the smallest size we sell and it's a great pump for smaller setups. If you plan on replacing a pump or building your own tank and need more output than what the 1 inch will give you, you might consider stepping up to the 1-1/2 inch Yamada or 2 inch Yamada pumps that we use on our larger systems.

We also carry Buna N replacement balls and Diaphragms for this pump.
