Note: Full flange-to-flange three-year warranty on all 00 Series circulators.Everything that goes into the0015-IFC 3-Speed - from thepowerful, high performancemotor to the durable 3-speedswitch - says "heavy duty". Withthe highest starting torque in itsclass, this circulator delivers theperformance and fine tuningcapabilities sure to satisfy themost demanding hydronicssystem installer. The 3-speed circulatorsfeature a removable, uni-bodyIntegral Flow Check (IFC) thatmaximizes flow, as well asprevents gravity flow, evenin the tallest buildings. Wiring isa snap thanks to an extra roomycapacitor box and convenientdual electrical knock-outs.The 0015 3-Speed pump is specifically designed for the wide range of flow andhead requirements of todays hydronic heating systems. Its 3-Speed switching capabilityprovides fine tuning control to match a wide combination of tube diameters and lengthof runs. The 0015 3-Speed is a direct replacement for the Grundfos UPS 15-58 3-Speed.The 0015 delivers the highest starting torque in its class and includes a removable,uni-body Integral Flow Check (IFC) that prevents gravity flow, reduces installationcosts and improves pump performance.Features:3-Speed SwitchFine tune to system requirementsHighest performance & starting torque in classHeavy duty construction for longer lifeRemovable high-flow Integral Flow Check (IFC)Replaceable cartridge designQuiet, efficient operationSelf lubricating, no mechanical sealWide range of applicationsCast Iron, flanged constructionReplacement Parts List:Casing O-Ring: 00R-001RP Flange Gasket Set: 007-007RP Capacitor or PC Board: 007-002RPCartridge Assembly Complete: 00R-005RPValve Assembly Trans/Relay: 0010-025RPReplacement Parts:(Not Included)
