Engineered to Perform
Fully bolted leak free mating surfaces:
All Yamada pumps incorporate registered fit bolted construction, which simplifies reassembly after maintenance. No leak-prone clamp bands are utilized.
One air valve fits all:
The NDP-40, 50 and 80 series pumps utilize one common air valve assembly, reducing parts inventory and assembly confusion. The NDP-20 and 25 have a common air valve as well. One air valve concept is used in all Yamada NDP series pumps!
Outside accessible:
Inspection or maintenance of every Yamada air valve can be performed without removing the pump from service.
Pilot valve:
Unique design is an individual modular pilot valve that actuates the air valve. It is maintenance- free, with no cumber- some snap rings or lubricated dynamic o-rings to replace or repair.
Diaphragm dynamics:
Extensive research has led to the development of an optimal stroke lenght that maximizes diaphragm life and performance while minimizing downtime and maintenance costs.
