{"product_id":"yamada-ndp-50bvw-pp","title":"Yamada NDP-50BVW-PP — 2\" Kynar PVDF Diaphragm Pump, Ultimate Diaphragm","description":"\u003cp\u003eYamada's NDP-50BVW-PP is a 2\" AODD pump in kynar pvdf, moving up to 164 GPM. It passes solids to 5\/16\" (8 mm) and handles fluid to 212°F (100°C).\u003c\/p\u003e\u003cp\u003eKynar (PVDF) resists concentrated acids, halogens and aggressive solvents that attack polypropylene, and carries a higher temperature ceiling than PP. 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. Ball check valves are the right choice for flooded-suction installations.\u003c\/p\u003e\u003cp\u003eThe non-metallic center body and glass-filled polypropylene air motor cut weight and remove a corrosion path in wet or chemically aggressive areas. 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.\u003c\/p\u003e\u003cp\u003eShipped from Texas with short lead times and strong pricing.
