The Yamada NDP-40BSH-NPT is a 1-1/2" air-operated double-diaphragm pump in stainless steel, rated to 107 GPM. It passes solids to 9/32" (7 mm) and handles fluid to 248°F (120°C).
A 316 stainless wetted path resists chlorides, organic acids and most process chemicals, and is the standard specification wherever wash-down or product purity matters. 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.
Supplied with NPT threaded connections. It runs on plant air with no electrical supply at the pump, self-primes, and will sit stalled against a closed discharge without damage — useful on intermittent or dead-headed duty.
Shipped from Texas with short lead times and strong pricing. If you are unsure which build fits your fluid, send us the application details and we will point you at the right part number.
