This clamped, NPT-ported standard build is a Trans-Flo Gold pump built for rugged outdoor duty and lower-quality air.\u003c\/p\u003e\u003cp\u003eAluminum wetted parts give a lightweight, durable metallic pump that is commonly chosen for oils, fuels, lubricants, paints and many water-based fluids; aluminum is generally not used for strong acids or caustics. PTFE has the broadest chemical resistance of the standard diaphragm materials and is the usual choice for aggressive chemicals and solvents; on this build the PTFE diaphragm is backed by a Neoprene diaphragm. Always confirm chemical compatibility with your fluid before ordering - Tank Supply Direct can check it for you.\u003c\/p\u003e\u003ch6\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eAnodized aluminum piston-style air valve system\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eBuilt for mining, construction, marine and utility work\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eTolerates lower-quality, unfiltered plant or compressor air\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAluminum wetted parts, PTFE diaphragms\u003c\/strong\u003e - standard NOMAD build 40-2691\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClamped construction\u003c\/strong\u003e - quick teardown for diaphragm and check-valve service\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAir-operated, no electric motor\u003c\/strong\u003e - flow adjusts with the air supply; no motor or controls at the pump\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel \/ MPN:\u003c\/strong\u003e 40-2691\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e NOMAD Trans-Flo Gold\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLiquid inlet\/outlet:\u003c\/strong\u003e 1-1\/2\" (38 mm) inlet \/ 1-1\/4\" (32 mm) outlet, NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAir inlet:\u003c\/strong\u003e 1\/2\" (13 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum flow rate:\u003c\/strong\u003e 62 gpm (235 lpm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum air supply pressure:\u003c\/strong\u003e 125 psig (8.6 bar)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum solids passage:\u003c\/strong\u003e 3\/16\" (4.8 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature range (PTFE elastomers, per NOMAD):\u003c\/strong\u003e 40°F to 220°F (4.4°C to 104.4°C)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions (D x W x H):\u003c\/strong\u003e 11.2\" x 15.4\" x 17.4\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight (per NOMAD manual):\u003c\/strong\u003e 38 lb\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003e\u003cstrong\u003eConstruction\u003c\/strong\u003e\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWetted body \/ manifolds:\u003c\/strong\u003e Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAir chambers:\u003c\/strong\u003e Polypropylene\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter section:\u003c\/strong\u003e Polypropylene\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAir valve:\u003c\/strong\u003e Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiaphragms:\u003c\/strong\u003e PTFE (Neoprene back-up)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCheck balls:\u003c\/strong\u003e PTFE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeats:\u003c\/strong\u003e Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eO-rings:\u003c\/strong\u003e PTFE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAssembly:\u003c\/strong\u003e Clamped\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e NOMAD pumps by JDA Global\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003e\u003cstrong\u003eApplications\u003c\/strong\u003e\u003c\/h6\u003e\u003cp\u003eNOMAD lists these industries for this pump: Automotive, Ceramics, Chemical, electronics\/semiconductor, Food\/Beverage, Mining\/Construction, Petroleum, Pharmaceutical, Wastewater.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePwr-Flo or Trans-Flo?\u003c\/strong\u003e NOMAD positions Trans-Flo for rugged outdoor work such as mining, marine and construction.
