YAMADA NDP5 DIAPHRAGM PUMP

YAMADA NDP5YAMADA NDP5 series AODD 1/4″ FLUID PORT pumps provide a maximum flow rate of 3.4 gallons per minute.
Diaphragm pump Yamada for this model available in aluminum, stainless steel (316), Kynar (PVDF), ground able acetal, and polypropylene construction.

ADVANTAGES :

• 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. Outside accessible, making it easy to fix / inspect.
• Unified Air Valve Concept
  Common-size air valve assemblies reduce parts confusion and inventory.
• Pilot Valve
  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.
