{"product_id":"yamada-ndp-25bvs-flange","title":"Yamada NDP-25BVS-FLANGE — 1\" Kynar PVDF Diaphragm Pump, Santoprene Diaphragm","description":"\u003cp\u003eYamada's NDP-25BVS-FLANGE is a 1\" AODD pump in kynar pvdf, moving up to 46.2 GPM. It passes solids to 1\/8\" (3 mm) and handles fluid to 180°F (82°C).\u003c\/p\u003e\u003cp\u003ePVDF construction handles the aggressive oxidising chemistry — chlorine, bromine, strong mineral acids — where polypropylene reaches its limit. Santoprene diaphragms and balls offer broad chemical compatibility with a long flex life, and are usually the best value where the duty cycle is heavy. Ball check valves are the right choice for flooded-suction installations.\u003c\/p\u003e\u003cp\u003eFitted with flanged manifolds rather than threaded connections. Air drive means no electrics at the pump, seal-less operation with nothing to leak at a shaft, and safe stalling against a closed discharge.\u003c\/p\u003e\u003cp\u003eShipped 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.\u003c\/p\u003e\u003ctable class=\"kad-specs\"\u003e\n\u003ccaption\u003eSpecifications\u003c\/caption\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eYamada\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eModel \/ MPN\u003c\/th\u003e\n\u003ctd\u003eNDP-25BVS-FLANGE\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eYamada item no.\u003c\/th\u003e\n\u003ctd\u003e853860\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003ePump type\u003c\/th\u003e\n\u003ctd\u003eAir-operated double-diaphragm (AODD)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eSeries\u003c\/th\u003e\n\u003ctd\u003eNDP-25\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003ePort size\u003c\/th\u003e\n\u003ctd\u003e1\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eMaximum flow\u003c\/th\u003e\n\u003ctd\u003e46.2 GPM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eAir supply pressure\u003c\/th\u003e\n\u003ctd\u003e20-100 PSI\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eMaximum fluid discharge pressure\u003c\/th\u003e\n\u003ctd\u003eSame as max air supply (1:1 pump)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eMaximum solids\u003c\/th\u003e\n\u003ctd\u003e1\/8\" (3 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eDisplacement per cycle\u003c\/th\u003e\n\u003ctd\u003eRubber 0.22 gal (833 cc)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eMaximum dry suction lift\u003c\/th\u003e\n\u003ctd\u003e18 ft\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eMaximum fluid temperature\u003c\/th\u003e\n\u003ctd\u003e180°F (82°C)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eCheck valve type\u003c\/th\u003e\n\u003ctd\u003eBall valve\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eBody \/ wetted materials\u003c\/th\u003e\n\u003ctd\u003eKynar (PVDF)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eDiaphragm material\u003c\/th\u003e\n\u003ctd\u003eSantoprene (TPO)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eBall material\u003c\/th\u003e\n\u003ctd\u003eSantoprene (TPO)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eAir motor\u003c\/th\u003e\n\u003ctd\u003eStandard\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eAir inlet\u003c\/th\u003e\n\u003ctd\u003e3\/8” Female NPT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eAir exhaust\u003c\/th\u003e\n\u003ctd\u003e3\/4” Female NPT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eOptions\u003c\/th\u003e\n\u003ctd\u003eFlanged manifold\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003cp class=\"kad-datasheet\"\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0979\/7681\/1822\/files\/KAD-Spec-Yamada-NDP-25BVS-FLANGE.pdf\" target=\"_blank\" rel=\"noopener\"\u003eDownload the NDP-25BVS-FLANGE specification sheet (PDF)\u003c\/a\u003e\u003c\/p\u003e","brand":"Yamada","offers":[{"title":"Default Title","offer_id":52476012462382,"sku":"NDP-25BVS-FLANGE","price":3100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0979\/7681\/1822\/files\/NDP-25BVS-FLANGE.jpg?v=1787220584","url":"https:\/\/kadpumpsandparts.com\/products\/yamada-ndp-25bvs-flange","provider":"KAD Pumps \u0026 Parts","version":"1.0","type":"link"}
