Since 1905, Yamada has been at the forefront in developing the most complete line of Air-Operated Double Diaphragm (AODD) pumps in the industry. Unmatched in quality, durability and availability, there’s no questions as to why more and more industries are coming to Yamada for their pumping needs. Diaphragm Pump NDP Series pumps are the backbone of the industrial line of air-powered double diaphragm pumps (AODD). A unique, patented air-valve design ensures stall-free operation throughout product life. Bolted construction and common component replaceable parts maximize uptime and increase profitability.
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.
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.
Optimal Stroke Length
Extensive research has led to the development of an optimal stroke length that maximizes diaphragm life and performance while minimizing downtime and maintenance costs.
As an ISO 9001 certified company, our engineering intellect and manufacturing processes are second to none. Yamada remains dedicated to the continuous development of the most complete line of AODD pumps available today. Our philosophy is quite simple. We offer the best product and support it with the best service. This is all backed by the lowest cost of ownership in the industry.
Yamada engineers designed and manufactured the most durable and reliable positive displacement pump capable of handling a wide variety of fluids with solids content for customers and industries worldwide.
