If you need to move product in a hurry and installation time is critical, consider the air operated diaphragm pump. Yamada have been making pumps for over 70 years. With numerous material configurations to suit all ranges of chemicals, let one of PUMPNSEAL’s specialists assist you with your next pump selection.

All Yamada pumps feature bolted construction, which eliminates leaks and simplifies post-maintenance reassembly. Bolted construction is superior to clamp band retainers, which frequently require frustrating, unnecessary leakage rebuilds from misalignment during reassembly. Inspection or maintenance of every Yamada air valve may be performed without removing the pump from service.

Unique to the Yamada design is an individual modular pilot valve that actuates the air valve. It is depressed slightly by the inner center disk creating a pressure drop at one end of the air valve, allowing shifting to occur. It is maintenance free with no cumbersome snap rings or lubricated dynamic o-rings to replace or repair. This product also features common-size air valve assemblies, which reduces parts confusion.

Extensive research has led to the development of an optimal stroke length that maximizes diaphragm life and performance while minimizing downtime and maintenance costs.
