Understanding Performance Curves ... 29 The Yamada Corporation has been a leading producer of industrial equipment since 1905, and of fluid handling products for over 60 years. As a leader in pneumatic pumping technology, Yamada is known in many industries worldwide for its innovative products, superior quality, and unmatched reliability. Other companies may claim to be innovators, but an impressive history of delivering new products and solving customer problems confirms Yamada's position as the industry leader. Yamada's reputation for manufacturing top quality products, allied with...

Rugged, Bolted Construction Engineered to Perform. Designed for Long Life. 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. Unified Air Valve Concept Common-size air valve assemblies reduce parts confusion. Pilot Valve Diaphragm Dynamics Unique to the Yamada...

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 pump...

Non-Metallic Components Features & Benefits – continued from preceding page. Non-Metallic Components Yamada engineers utilize state-of-the-art solid modeling and finite element analysis techniques, including rib and shell methods of injection molding to design non-metallic parts structure. This patented technique greatly increases the component strength and reduces material usage. NDP-40, 50, & 80 Series Stainless Steel Pump Base for Non-Metallic Pumps The tubular 304 Stainless Steel base was designed to simplify rebuilding procedures and to absorb weight distribution. Maintenance...
