{"product_id":"yamada-ndp-20bas-d","title":"Yamada NDP-20BAS-D — 3\/4\" Aluminum Diaphragm Drum Pump, Santoprene Diaphragm","description":"\u003cp\u003eThe NDP-20BAS-D covers 3\/4\" transfer duty as an air-operated double-diaphragm pump in aluminum, rated to 31.7 GPM. It passes solids to 1\/16\" (2.0 mm) and handles fluid to 180°F (82°C).\u003c\/p\u003e\u003cp\u003eAluminium construction handles solvents, lubricating oils and hydrocarbon-based fluids well, and takes mechanical abuse better than a plastic body in a busy plant. Santoprene diaphragms and balls offer broad chemical compatibility with a long flex life, and are usually the best value where the duty cycle is heavy. Ball check valves are the right choice for flooded-suction installations.\u003c\/p\u003e\u003cp\u003eSupplied as a drum-mount package with dip tube and bung adapter. Air drive means no electrics at the pump, seal-less operation with nothing to leak at a shaft, and safe stalling against a closed discharge.\u003c\/p\u003e\u003cp\u003eShipped from Texas with short lead times and strong pricing.
