DIAPHRAGM PUMP NDP50 YAMADA 2 Inch Port AODD pumps provide a maximum flow rate of 164 gallons per minute. Pumps are available in aluminum, stainless steel (316), Kynar (PVDF), groundable 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 diaphragm pump 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.
