{"product_id":"yamada-ndp-20bah-d","title":"Yamada NDP-20BAH-D — 3\/4\" Aluminum Diaphragm Drum Pump, Hytrel Diaphragm","description":"\u003cp\u003eThe NDP-20BAH-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 248°F (120°C).\u003c\/p\u003e\u003cp\u003eThe aluminum body suits solvents, fuels, oils and paints — the general-industrial fluids where a metal pump is wanted but stainless is more than the job needs. Hytrel diaphragms and balls carry the highest temperature rating in the range and resist abrasion well, which suits hot oils and particulate-bearing fluids. 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.
