Rugged, Bolted Construction 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. Outside-Accessible Air Valve Inspection or maintenance of every Yamada air valve may be performed without removing the pump from service. Unified Air Valve Concept Common-size air valve assemblies reduce parts confusion. Pilot Valve Optimal Stroke Length Extensive research has led to the development...

Yamada Patented Air Valve Technology ® Yamada air valve technology is the heart of the air-powered double diaphragm pump and determines reliability. Yamada holds three patents on its field proven valve and enjoys a superior reputation throughout the industry. Unified Air Valve Concept To simplify, Yamada offers two common size air valve assemblies within five sizes of pumps (3/4" & 1" pumps and 1-1­ 2", 2" & 3" pumps) further reducing / reassembly confusion and parts inventory. Other airpowered double diaphragm pump manufacturers offer multiple air valve designs and revisions in an effort to address...

Fair Guideline of Pump size and Flow rate Operation with the maximum cycle shorten the pump lifetime. To optimize pump performance and lifetime, please select pump in reference to this guideline. Recommended Flow Rate by Pump Size Using Performance Curves Specified Suction Lift Decrease of Rated Pump Flow (%) Decrease in Flow Rate as Suction Head Lift Rises * Select a pump with safety margin (1.5 times or higher) appropriate for the required conditions with taking effective use of a diaphragm and other expendables into consideration. * The performance curve shown on the right indicates the data...
