Yamada NDP-80 Series – 3" Air-Operated Double Diaphragm Pump

The Yamada NDP-80 is a high-capacity 3" air-operated double diaphragm (AODD) pump engineered for large-scale industrial fluid transfer. Designed for continuous, heavy-duty use, it can handle up to 814 litres per minute, making it ideal for processing corrosive, abrasive, viscous, or solids-laden fluids.

Available in durable materials such as aluminium, stainless steel, polypropylene, and PVDF, the NDP-80 is built to withstand aggressive chemical environments while maintaining structural integrity and reliability. Its bolted body design ensures leak-free operation, while the advanced, non-lubricated air valve system provides stall-free performance and reduced maintenance over time.

With outstanding suction lift capability and wide material compatibility, the NDP-80 is the go-to solution for industries including chemical manufacturing, wastewater treatment, mining, and general processing.
