Yamada NDP-5FST Air Operated Double Diaphragm Pump

Description:

The Yamada NDP-5FST Air Operated Double Diaphragm Pump is used in low-flow fluid transfer systems requiring reliable pneumatic operation and corrosion-resistant performance. Commonly installed in chemical dosing skids, laboratory systems, ink and coating transfer equipment, and small-scale industrial processing units. Maintenance teams and system integrators use this pump for precise fluid handling, system replacement, retrofit, and safe transfer of aggressive or sensitive media.

Applications:

The Yamada NDP-5FST is used in industrial and laboratory environments where controlled, low-volume fluid transfer is required with chemical compatibility. It is commonly applied in chemical injection systems, coatings and ink handling, pharmaceutical processing, and small water treatment setups where air-operated pumps provide safe, leak-resistant operation without electrical components.
