Yamada's NDP-40BPH is a 1-1/2" AODD pump in polypropylene, moving up to 107 GPM. It passes solids to 9/32" (7 mm) and handles fluid to 180°F (82°C).
A glass-filled polypropylene wetted path handles dilute acids, alkalis and brines without the galvanic issues a metal body brings, making it the usual pick for chemical transfer and wastewater duty. 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.
Being air-driven, it needs no motor starter or electrical classification at the pump, self-primes from dry, and can be dead-headed and left stalled under pressure.
We ship from Texas, quote honest lead times and price sharply. Tell us the fluid, temperature and flow you need and we will confirm the right configuration before you order.
