Yamada's NDP-20BPC-PP-D is a 3/4" AODD pump in polypropylene, moving up to 31.7 GPM. It passes solids to 1/16" (2.0 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. Neoprene diaphragms and balls give balanced service across mild chemicals, oils and water, and are the economical default where nothing aggressive is being moved. Ball check valves are the right choice for flooded-suction installations.
The non-metallic center body and glass-filled polypropylene air motor cut weight and remove a corrosion path in wet or chemically aggressive areas. Supplied as a drum-mount package with dip tube and bung adapter. 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.
