{"product_id":"dab-evosta-2-ecm-circulator","title":"Dab Pumps - EVOSTA2 ECM Wet Rotor Circulator","description":"\u003ch2\u003eDAB EVOSTA2 ECM Wet Rotor Circulator\u003c\/h2\u003e\u003cp\u003eThe DAB EVOSTA2 is a wet rotor electronic circulator built on a permanent magnet synchronous motor with an electronic driver, which DAB describes as an ECM or Electronic Commutation Motor, also called a brushless DC motor. The pump body is cast iron with cataphoresis treatment, the motor casing is AISI 304 stainless steel, the rotor can flange is AISI 316 stainless steel, the impeller is Ultrason, the motor shaft is ceramic alumina with alumina bearings and a graphite axial bearing, the outer shell and cover are polycarbonate and the seals are EPDM. It is rated IP X5, described by DAB as NEMA 4X, with class F insulation and TF 110. Power input is single-phase 110-127 V at 60 Hz, drawing 4 W to 41 W and 0.064 A to 0.61 A, with an energy efficiency index of EEI 0.23 or better. The flange is an oval 2-bolt pattern on a 6-3\/8 in centre distance and DAB rates sound at 43 dB(A) or less.\u003c\/p\u003e\u003cp\u003eAn EVOSTA2 is a direct modern replacement for an old three-speed circulator: DAB built it to the same dimensions as the VA series and it covers heads up to 18 ft with a single model instead of a shelf of them. Its built-in electronics sense what the system is asking for and adapt the circulator's output to match, which is where the energy saving and the quieter operation come from. Setup is one sequential button giving three regulating modes with three curves each: proportional differential pressure, constant differential pressure and constant curve. A breather plug vents the system and manually releases the motor shaft. The pump is self-protected against overload, lack of phase, excess temperature and over- and under-voltage. DAB rates it for water in heating and air conditioning systems and for industrial water circuits, with up to 30 percent glycol.\u003c\/p\u003e\u003ch3\u003eAvailable Models\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eEVOSTA2 55: 41 W maximum input, max head 18 ft, max flow 15.1 GPM, without display\u003c\/li\u003e\n\u003cli\u003eEVOSTA2D 55: 41 W maximum input, max head 18 ft, max flow 15.1 GPM, with display showing the real working point\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePump Type: Wet rotor electronic circulator, ECM permanent magnet synchronous motor\u003c\/li\u003e\n\u003cli\u003ePower Supply: 1 x 110-127 V, 60 Hz\u003c\/li\u003e\n\u003cli\u003ePower Input P1: 4 W to 41 W\u003c\/li\u003e\n\u003cli\u003eCurrent In: 0.064 A to 0.61 A\u003c\/li\u003e\n\u003cli\u003eEnergy Efficiency Index: EEI 0.23 or better\u003c\/li\u003e\n\u003cli\u003eOperating Range: 0.8 to 15.1 GPM with head up to 18 ft\u003c\/li\u003e\n\u003cli\u003eMaximum Working Pressure: 145 psi\u003c\/li\u003e\n\u003cli\u003eMinimum Working Pressure: 14.5 psi (1 bar)\u003c\/li\u003e\n\u003cli\u003eLiquid Temperature: 14 F to 230 F\u003c\/li\u003e\n\u003cli\u003eMaximum Ambient Temperature: 104 F\u003c\/li\u003e\n\u003cli\u003eMinimum Suction Pressure at 194 F: 32.8 ft.c.w.\u003c\/li\u003e\n\u003cli\u003eSound Pressure: 43 dB(A) or less\u003c\/li\u003e\n\u003cli\u003eFlange: Oval 2-bolt, 6-3\/8 in centre distance\u003c\/li\u003e\n\u003cli\u003ePump Body: Cast iron with cataphoresis treatment\u003c\/li\u003e\n\u003cli\u003eMotor Casing: AISI 304 stainless steel\u003c\/li\u003e\n\u003cli\u003eRotor Can Flange: AISI 316 stainless steel\u003c\/li\u003e\n\u003cli\u003eImpeller: Ultrason\u003c\/li\u003e\n\u003cli\u003eMotor Shaft: Ceramic, alumina\u003c\/li\u003e\n\u003cli\u003eProtection Class: IP X5, NEMA 4X\u003c\/li\u003e\n\u003cli\u003eInsulation Class: F\u003c\/li\u003e\n\u003cli\u003eTF Class: TF 110\u003c\/li\u003e\n\u003cli\u003eInstallation: Horizontal motor axis\u003c\/li\u003e\n\u003cli\u003ePumped Liquid: Clean, free of solids and mineral oils, non-viscous, chemically neutral, glycol max 30 percent\u003c\/li\u003e\n\u003cli\u003eCertification: CSA and UL, per DAB USA 60 Hz price list\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eECM permanent magnet motor\u003c\/strong\u003e that draws as little as 4 W and tops out at 41 W\u003c\/li\u003e\n\u003cli\u003eNine settings from one sequential button: proportional differential pressure, constant differential pressure and constant curve, three curves each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEVOSTA2D adds a display\u003c\/strong\u003e that shows the real working point; in DAB's own designation index 2 means without display and 2d means with display, so the D version is not a twin or double-head pump\u003c\/li\u003e\n\u003cli\u003eDrop-in replacement for old three-speed circulators, dimensionally matched to the VA series\u003c\/li\u003e\n\u003cli\u003eCovers heads up to 18 ft with a single model\u003c\/li\u003e\n\u003cli\u003eEEI 0.23 or better\u003c\/li\u003e\n\u003cli\u003eSelf-protected against overload, lack of phase, excess temperature and over- and under-voltage\u003c\/li\u003e\n\u003cli\u003eBreather plug for venting and manual release of the motor shaft\u003c\/li\u003e\n\u003cli\u003eIP X5 water-resistant electronics, rated by DAB as NEMA 4X\u003c\/li\u003e\n\u003cli\u003eRotates 360 degrees around a vertical axis, with a check valve and 2-bolt flange available\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eIdeal Applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eResidential hydronic heating loops and zone circulation\u003c\/li\u003e\n\u003cli\u003eAir conditioning and chilled water circulation\u003c\/li\u003e\n\u003cli\u003eRadiant floor heating systems\u003c\/li\u003e\n\u003cli\u003eBoiler primary and secondary loops\u003c\/li\u003e\n\u003cli\u003eDirect replacement for an aging three-speed circulator\u003c\/li\u003e\n\u003cli\u003eIndustrial water circuits\u003c\/li\u003e\n\u003cli\u003eGlycol systems up to 30 percent glycol\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Valley Milan","offers":[{"title":"EVOSTA2 55","offer_id":52945986060599,"sku":"DAB60192406","price":371.0,"currency_code":"USD","in_stock":true},{"title":"EVOSTA2D 55","offer_id":52945986093367,"sku":"DAB60192407","price":407.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/0341\/5863\/files\/dab-evosta-2-ecm-circulator-1.jpg?v=1788482525","url":"https:\/\/www.blacklabelsupply.io\/products\/dab-evosta-2-ecm-circulator","provider":"BLACK LABEL","version":"1.0","type":"link"}
