The unit features a cast iron casing and bracket with a stainless steel impeller and shaft. Connections are 1.5 inches on both the suction and discharge ports. A replaceable bearing cartridge assembly isolates ball bearings from system fluid, supporting operating temperatures up to 250 degrees F. Licensed plumbers and mechanical contractors typically handle installation and commissioning of this equipment.\u003c\/p\u003e\n\u003cp\u003eThis pump is suited for closed-loop hydronic systems where an operator-selected driver motor will be matched to the 4.75 inch nominal impeller diameter. The rear pull-out design allows full removal of the motor and rotating assembly for servicing without breaking into the connected piping. The fluid path uses a mechanical seal assembly with a ceramic seat, carbon rotor, and EPT elastomers, which supports routine field maintenance with standardized components. The bearing cartridge and seal configuration are designed for straightforward replacement during scheduled service intervals.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCast iron casing and bracket with stainless steel impeller and shaft for durability in hydronic service\u003c\/li\u003e\n  \u003cli\u003e1.5 inch suction and 1.5 inch discharge connections for direct inline piping installation\u003c\/li\u003e\n  \u003cli\u003e4.75 inch nominal impeller diameter — motor must be sourced and matched separately\u003c\/li\u003e\n  \u003cli\u003eReplaceable bearing cartridge assembly isolates ball bearings from system fluid\u003c\/li\u003e\n  \u003cli\u003eMechanical seal with ceramic seat, carbon rotor, and EPT elastomers for reliable fluid containment\u003c\/li\u003e\n  \u003cli\u003eRear pull-out design allows motor and rotating component removal without disturbing piping\u003c\/li\u003e\n  \u003cli\u003eRated for operating temperatures up to 250 degrees F\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style inline circulator for closed-loop hydronic heating and cooling systems requiring a separately sourced driver motor matched to a 4.75 inch impeller.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or mechanical contractor in accordance with applicable local mechanical codes and ASHRAE hydronic system guidelines. Shut down and depressurize the hydronic system and allow it to cool before working on any wet components. An appropriately sized and rated motor must be selected and mounted before the pump is placed into service. Verify flange bolt torque and seal integrity before returning the system to operating pressure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSuction Connection\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDischarge Connection\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eImpeller Diameter\u003c\/strong\u003e: 4.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Operating Temperature\u003c\/strong\u003e: 250 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCasing Material\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eImpeller Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShaft Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeal Assembly\u003c\/strong\u003e: Ceramic seat, carbon rotor, EPT elastomers\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMotor\u003c\/strong\u003e: Not included (less motor configuration)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: TACO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1611eae8s000000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TACO","offers":[{"title":"Default Title","offer_id":51620751049010,"sku":"1611EAE8S000000","price":1153.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/77b47aed9d90596f000469e665e08be7_cce383e6-6731-4f36-9ad9-eb761567fbf6.jpg?v=1787345963","url":"https:\/\/voomisupply.com\/products\/taco-1611eae8s000000-inline-circulator-pump-less-motor","provider":"Voomi Supply","version":"1.0","type":"link"}
