{"product_id":"easdcpsp","title":"Precise Screw Pump (5 L) for Slot Die Coater, EASDCPSP","description":"\u003cp\u003eFor high-precision slot-die coating of NMP-based cathode slurries, a precise screw pump (specifically a Progressive Cavity Pump) is often considered superior to a peristaltic pump for industrial or high-end R\u0026amp;D. While peristaltic pumps are easier to clean, screw pumps provide a pulseless, continuous flow that is critical for eliminating \"chatter marks\" (thickness ripples) on your electrodes at higher coating speeds.\u003c\/p\u003e\n\u003cp\u003eA screw pump consists of a single-helix metallic rotor and a double-helix elastic stator. As the rotor turns inside the stator, it creates a series of sealed \"cavities\" that move from the suction side to the discharge side. (1) \u003cstrong\u003eVolumetric Precision\u003c\/strong\u003e: The amount of slurry delivered is directly proportional to the rotation speed. (2) \u003cstrong\u003ePulseless Delivery\u003c\/strong\u003e: Unlike peristaltic or piston pumps, the geometry of the cavities ensures that the displaced volume is constant. This results in an incredibly smooth \"coating bead\" at the slot-die lip.\u003c\/p\u003e\n\u003ctable style=\"height: 201.2px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 17.9856%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%; height: 35.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eEASDCPSP (E-A-SDC-PSP)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 17.9856%;\"\u003e\u003cem\u003ePower\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%;\"\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eAC220V±10%, single phase, 50\/60Hz, ~500 W\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 17.9856%;\"\u003e\u003cem\u003eFeeding Speed Range\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%;\"\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003e5.2 to 186 mL\/min, adjustable\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"font-size: 0.875rem;\"\u003eStirring speed: ~30 rpm\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 17.9856%;\"\u003e\u003cem\u003eSlurry Tank\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%;\"\u003e\n\u003cul\u003e\n\u003cli\u003e5 L in total, SS304 (2L and 10 L are also available upon request)\u003c\/li\u003e\n\u003cli\u003eThe stator is made of EPDM.\u003c\/li\u003e\n\u003cli\u003eThe rotor is made of SUS316\u003c\/li\u003e\n\u003cli\u003eIt is compatible with NMP solvent\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 17.9856%;\"\u003e\u003cem\u003eAir Compressor\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%;\"\u003e\n\u003cul\u003e\n\u003cli\u003eIf the screw pump is connected with the R2R coater, the gas pressure is coming from the coater by a connected gas pressure tubing.\u003c\/li\u003e\n\u003cli\u003eIf the screw pump is individually purchased or used, then an individual air compressor (\u003ca href=\"https:\/\/echemsupplies.com\/products\/euqofgc?variant=47513044156646\"\u003eEUQOFGC\u003c\/a\u003e) is needed. \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e          \u003ca href=\"https:\/\/echemsupplies.com\/products\/euqofgc?variant=47513044156646\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/EUQOFGC_main_100x100.png?v=1775414665\" alt=\"\" style=\"float: none;\"\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 17.9856%;\"\u003e\u003cem\u003eApplication\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%;\"\u003e\n\u003cul\u003e\n\u003cli\u003eIt is a good option for roll-to-roll slot die coaters, such as \u003ca href=\"ESSMR2RC\"\u003eESSMR2RC\u003c\/a\u003e, \u003ca href=\"https:\/\/echemsupplies.com\/products\/esmmr2rc?variant=47523596108006\"\u003eESMMR2RC\u003c\/a\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 17.9856%;\"\u003e\u003cem\u003eDimension\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%;\"\u003e\n\u003cul\u003e\n\u003cli\u003eL920×W230×H830mm\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 17.9856%;\"\u003e\u003cem\u003eWeight\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%;\"\u003e\n\u003cul\u003e\n\u003cli\u003e~ 35 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\n\u003cp\u003e\u003cstrong\u003eReferences\u003c\/strong\u003e:\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/link.springer.com\/article\/10.1007\/s12541-020-00425-6\"\u003eH.
