Pumps

Yamada builds their pumps with quality and innovation. This is the cornerstone of the Yamada design and manufacturing.

Their pumps are engineered to perform and built to last.

Just a few advantages of Yamada pumps:

• Fully bolted leak free mating surfaces: All Yamada pumps incorporate registered fit bolted construction, which simplifies reassembly after maintenance. No leakprone clamp bands are utilized.
• One air valve fits all: The NDP-40, 50 & 80 series pumps utilize one common air valve assembly, reducing parts inventory and assembly confusion. The NDP-20 & 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 cumbersome 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.
