AIR OPERATE DOUBLE DIAPHRAGM PUMP
YAMADA

Mating Surfaces
All Yamada pumps incorporate bolted construction, which eliminates leaks and simplifies reassembly after maintenance. Many competitors utilise clamp band construction, which frequently requires frustrating and unnecessary rebuilds due to leakage 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 (Link)
Common size air valve assemblies reduce parts confusion.

Pilot Valve
Unique to the Yamada design is an individual modular pilot valves that actuates the air valve. It is depressed slightly by the inner centre 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.

Diaphragm Dynamics
Extensive research had led to the development of an optimal stroke length that maximizes diaphragm, like and performance while minimizing downtime and maintenance costs.
