    This Yamada dual diaphragm pump is Air Operated and requires an external air source and will deliver approximately 200 PSI which allows for smaller spray wand tips.

    Our 1" Duel Diaphragm Pneumatic Pump is the smaller version of our 2" pump and 1-1/2" pumps that we use on our larger systems. We also carry replacement balls and Buna Diaphragms for this pump.
