{"product_id":"edsrvvp","title":"Double Stage Rotary Vane Vacuum Pump (132-156 L\/min), EDSRVVP","description":"\u003cp\u003eA double-stage rotary vane vacuum pump is the go-to choice when you need a significantly deeper vacuum (10^{-3} to 10^{-4} mbar) and higher pumping speeds at a lower cost. In battery research, these are typically used for large-scale vacuum drying ovens or backing glovebox purification systems rather than the sealing machine itself, due to the risk of oil back-streaming.\u003c\/p\u003e\n\u003cp\u003eA rotary vane pump uses centrifugal force to move vanes within a cylindrical housing, trapping and compressing air. A \"Double Stage\" pump essentially connects two of these mechanisms in series. \u003cstrong\u003eStage 1 (High Vacuum Stage)\u003c\/strong\u003e: Takes in the gas from the inlet at low pressure and compresses it. \u003cstrong\u003eStage 2 (Low Vacuum Stage)\u003c\/strong\u003e: Takes the exhaust from the first stage and compresses it further to atmospheric pressure for discharge.\u003c\/p\u003e\n\u003cp\u003eThe key features of a double-stage rotary vane vacuum pump are show below: (1) \u003cstrong\u003eUltimate Vacuum\u003c\/strong\u003e: It can reach pressures as low as 10^{-3} mbar. This is orders of magnitude deeper than a standard diaphragm pump, which is essential for removing deep-seated moisture in electrode materials. (2) \u003cstrong\u003eGas Ballast\u003c\/strong\u003e: The gas ballast can leak a small amount of dry air\/nitrogen into the second stage to prevent vapors (like water or electrolyte) from condensing into the pump oil. (3) \u003cstrong\u003eAnti-Suckback Valve\u003c\/strong\u003e: A critical safety feature. If the power fails, this internal valve prevents the pump oil from being sucked back into your vacuum chamber or pouch cell sealer.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"height: 495.6px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 47.6px;\"\u003e\n\u003ctd style=\"width: 17.9856%; height: 47.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%; height: 47.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eEDSRVVP (E-DSRVVP)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 47.6px;\"\u003e\n\u003ctd style=\"width: 17.9856%; height: 47.6px;\"\u003e\u003cem\u003ePower\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%; height: 47.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eAC110 or 220V±10%, single phase, 50\/60Hz, ~400 W \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 67.2px;\"\u003e\n\u003ctd style=\"width: 17.9856%; height: 67.2px;\"\u003e\u003cem\u003eVacuum Flow Rate\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%; height: 67.2px;\"\u003e\n\u003cul\u003e\n\u003cli\u003e50 Hz: 8 m3\/h (132 L\/min)\u003c\/li\u003e\n\u003cli\u003e60 Hz: 9.6 m3\/h (156 L\/min)\u003c\/li\u003e\n\u003cli\u003eHigher vacuum rates, such as 312 L\/min, 474 L\/min, 594 L\/min can be supplied upon request. \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 47.6px;\"\u003e\n\u003ctd style=\"width: 17.9856%; height: 47.6px;\"\u003e\u003cem\u003eVacuum Level\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%; height: 47.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eMax. 4*10^(-3) Torr\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 47.6px;\"\u003e\n\u003ctd style=\"width: 17.9856%; height: 47.6px;\"\u003e\u003cem\u003eInlet\/Outlet Port\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%; height: 47.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eKF25 (KF16 is available upon request)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 47.6px;\"\u003e\n\u003ctd style=\"width: 17.9856%; height: 47.6px;\"\u003e\u003cem\u003eOil Level\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%; height: 47.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003e0.6-1.0 L\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 47.6px;\"\u003e\n\u003ctd style=\"width: 17.9856%; height: 47.6px;\"\u003e\u003cem\u003eMotor Rotation Speed\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%; height: 47.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003e1440\/1720 rpm (50\/60 Hz)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 47.6px;\"\u003e\n\u003ctd style=\"width: 17.9856%; height: 47.6px;\"\u003e\u003cem\u003eNoise Level\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%; height: 47.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003e≤52 dB\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 47.6px;\"\u003e\n\u003ctd style=\"width: 17.9856%; height: 47.6px;\"\u003e\u003cem\u003eDimension\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%; height: 47.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eL445 * W144 * H217 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 47.6px;\"\u003e\n\u003ctd style=\"width: 17.9856%; height: 47.6px;\"\u003e\u003cem\u003eWeight\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%; height: 47.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003e~21 kg\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"FY","offers":[{"title":"Default Title","offer_id":47513025282278,"sku":"EDSRVVP","price":1499.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/EDSRVVP_main.png?v=1775410712","url":"https:\/\/echemsupplies.com\/products\/edsrvvp","provider":"EChem Supplies","version":"1.0","type":"link"}
