Yamada's NDP-15FPW is a 1/2" AODD pump in polypropylene, moving up to 13.5 GPM. It passes solids to 1/32" (1 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. Yamada's Ultimate two-piece diaphragm pairs a PTFE wetted face with an elastomer backer, giving PTFE chemical resistance with markedly longer flex life than solid PTFE. Flat check valves are the right choice where the pump has to lift liquid rather than being fed by gravity.
It self-primes, tolerates running dry, and stalls harmlessly against a closed valve, so it suits batching and intermittent transfer where a centrifugal pump would be a poor fit.
Texas-based, with short lead times and pricing that reflects our supply position. Not sure this is the right build? Send us the fluid and duty and we will confirm.
