Yamada Diaphragm Pumps


Patented Non-Lubricated Air Valve. Yamada® Patented Non-Lubricated Air Valve with Non-centering Stall-free Spring Incorporated in every Yamada Air Powered Double Diaphragm Food pump. 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.


Double Diaphragm Transfer Pumps Rugged, Bolted Construction

All Yamada transfer pumps feature bolted construction, which eliminates leaks and simplifies post-maintenance reassembly. Bolted construction is superior to clamp band retainers. Yamada offers Diaphragm transfer pumps in metallic and non-metallic body materials. The non-metallic transfer pump features pumps injection molded solid plastic. Yamada double diaphragm pumps are available in conductive Acetal, Polypropylene, Kynar, aluminum, stainless steel, cast iron, TEFLON (tm) and PTFE. Yamada double diaphragm pumps are available and in use in almost for every industrial application.

Yamada Powder Pumps are designed to move bulk powders more effectively throughout your process vs. other unsafe and labor intensive means. These heavy duty pumps will consistently transfer fine-grained, low-bulk density dry powders in a dust-free operation.

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.
