{"product_id":"stx-def-series-sliding-vane-pumps","title":"STX-DEF Series Sliding Vane Pumps","description":"\u003cp\u003eBlackmer STX-DEF Series pumps are 316 stainless steel sliding vane pumps built and certified for Diesel Exhaust Fluid service. Every pump is tested with de-ionized water and meets or exceeds the industry specifications for DEF aqueous urea solutions (AUS32), also known as AdBlue. Construction includes external ball bearings, non-metallic Duravanes, PTFE elastomers, Blackmer chemical mechanical seals, an integral adjustable relief valve and a double-ended keyed shaft.\u003c\/p\u003e\n\u003cp\u003eSliding vane technology is what makes these pumps well suited to fast off-loading. The vanes self-compensate as they wear, so flow rates hold up over the life of the pump, and the design self-primes and will run dry for short periods to strip suction lines clean without damage. A 6,000 gallon (22,700 liter) tanker can be off-loaded in as little as 24 minutes with an STX3-DEF. Internal wear is limited almost entirely to the vanes themselves, which can be replaced with ordinary hand tools without pulling the pump out of the piping.\u003c\/p\u003e\n\u003ch2\u003eModels and Performance\u003c\/h2\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003cth\u003eNominal Flow Rate\u003c\/th\u003e\n\u003cth\u003eViscosity Range\u003c\/th\u003e\n\u003cth\u003eSpeed\u003c\/th\u003e\n\u003cth\u003eShipping Weight\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSTX2A-DEF\u003c\/td\u003e\n\u003ctd\u003e16 to 60 gpm (61 to 227 L\/min)\u003c\/td\u003e\n\u003ctd\u003e0.2 to 990 cP\u003c\/td\u003e\n\u003ctd\u003e150 to 800 rpm\u003c\/td\u003e\n\u003ctd\u003e70 lb (32 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSTX1220A-DEF\u003c\/td\u003e\n\u003ctd\u003e45 to 92 gpm (170 to 348 L\/min)\u003c\/td\u003e\n\u003ctd\u003e0.2 to 22 cP\u003c\/td\u003e\n\u003ctd\u003e700 to 1,200 rpm\u003c\/td\u003e\n\u003ctd\u003e70 lb (32 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSTX3-DEF\u003c\/td\u003e\n\u003ctd\u003e80 to 250 gpm (303 to 946 L\/min)\u003c\/td\u003e\n\u003ctd\u003e0.2 to 4,250 cP\u003c\/td\u003e\n\u003ctd\u003e300 to 800 rpm\u003c\/td\u003e\n\u003ctd\u003e132 lb (60 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003eAll three models share the same pressure and temperature limits: 125 psi (8.6 bar) maximum differential pressure, 175 psi (12.1 bar) maximum working pressure, and a temperature range of -25°F to 240°F (-32°C to 115°C).\u003c\/p\u003e\n\u003ch2\u003eFeatures and Benefits\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eMeets or exceeds all industry specifications for DEF aqueous urea solutions (AUS32) and AdBlue\u003c\/li\u003e\n\u003cli\u003e316 stainless steel cylinder, heads and relief valve cover with external ball bearing construction\u003c\/li\u003e\n\u003cli\u003eBlackmer chemical mechanical seals and non-metallic Duravanes for long life in corrosive service\u003c\/li\u003e\n\u003cli\u003eIntegral adjustable relief valve protects the pump against excessive pressure\u003c\/li\u003e\n\u003cli\u003eSelf-adjusting vanes maintain flow rates as they wear\u003c\/li\u003e\n\u003cli\u003eExcellent self-priming and dry-run capability for line stripping and blowing lines clean\u003c\/li\u003e\n\u003cli\u003ePump design minimizes shear and agitation of the fluid\u003c\/li\u003e\n\u003cli\u003eVanes replace with ordinary hand tools, without removing the pump from the piping system\u003c\/li\u003e\n\u003cli\u003eHigh suction lift, low maintenance and low life-cycle cost\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eOrdering Options\u003c\/h2\u003e\n\u003cp\u003eThree choices are made on this page.
