Rated at 0.30 HP and 115 volts, it delivers a maximum flow rate of 43 GPM (2,580 GPH) with a maximum head of 19 feet. The pump body, motor housing, and switch case are all cast iron for long-term durability in wet, demanding environments. A vortex-style engineered plastic impeller allows water and up to 1\/2-inch spherical solids to pass freely. The unit ships with an LED plug that provides a quick visual confirmation of power status at the outlet. Every unit is factory-tested against its published performance curve before leaving the facility.\u003c\/p\u003e\n\u003cp\u003eThis pump is designed for continuous-duty basement sump installations where groundwater removal is the primary need. The solid white polypropylene float cannot become waterlogged, ensuring reliable automatic on\/off cycling. Turn-on occurs at a water level of 7-1\/4 inches and the pump shuts off at 3 inches. Oil-filled cooling and a Class B motor insulation rating support sustained operation. A 9-foot, UL-listed 3-wire grounded cord provides reach from the sump pit to a nearby outlet. Licensed plumbers and experienced contractors are the typical installers for this type of primary sump pump.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCast iron pump body, motor housing, and switch case for durability in basement sump environments\u003c\/li\u003e\n  \u003cli\u003eVortex impeller handles up to 1\/2-inch spherical solids without clogging\u003c\/li\u003e\n  \u003cli\u003eSolid polypropylene float resists waterlogging for reliable automatic operation\u003c\/li\u003e\n  \u003cli\u003eLED plug provides instant visual power confirmation at the outlet\u003c\/li\u003e\n  \u003cli\u003eAuto-reset thermal overload protects the motor from overheating\u003c\/li\u003e\n  \u003cli\u003eFactory submerged and tested to published performance curve before shipment\u003c\/li\u003e\n  \u003cli\u003eStainless steel hardware, float guard, switch arm, and identification tag resist corrosion\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style primary sump pump for residential basement sump pit applications requiring automatic float-operated groundwater removal.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with local plumbing codes and IPC guidelines. Disconnect power at the breaker before lowering the pump into the pit or servicing any components. Verify the discharge connection is a 1-1\/2-inch NPT fitting and that the discharge line is properly routed away from the foundation. Confirm the sump pit dimensions allow adequate float travel between the 3-inch shutoff level and the 7-1\/4-inch turn-on level.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHorsepower\u003c\/strong\u003e: 0.30 HP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 115 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage\u003c\/strong\u003e: 9.7 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHertz\u003c\/strong\u003e: 60 Hz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePhase\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRPM\u003c\/strong\u003e: 1,550\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMax Flow Rate\u003c\/strong\u003e: 43 GPM (2,580 GPH)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Head\u003c\/strong\u003e: 19 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSolids Handling\u003c\/strong\u003e: 1\/2-inch spherical solids\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDischarge\u003c\/strong\u003e: 1-1\/2-inch NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTurn-On Level\u003c\/strong\u003e: 7-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTurn-Off Level\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Liquid Temperature\u003c\/strong\u003e: 130 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperation\u003c\/strong\u003e: Automatic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMotor Type\u003c\/strong\u003e: Shaded Pole\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMotor Insulation\u003c\/strong\u003e: Class B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMotor Protection\u003c\/strong\u003e: Auto-reset thermal overload\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCooling\u003c\/strong\u003e: Oil filled\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eImpeller Type\u003c\/strong\u003e: Vortex\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eImpeller Material\u003c\/strong\u003e: Engineered Plastic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePump Body Material\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMechanical Seals\u003c\/strong\u003e: Carbon and ceramic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUpper Bearing\u003c\/strong\u003e: Sleeve bearing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLower Bearing\u003c\/strong\u003e: Sleeve bearing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCord Length\u003c\/strong\u003e: 9 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCord Type\u003c\/strong\u003e: UL listed, 3-wire, grounded plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 10.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 10.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 7.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 23 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWarranty\u003c\/strong\u003e: 3 years\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: United States\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: ZOELLER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: m53 sump p\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ZOELLER","offers":[{"title":"Default Title","offer_id":51138433286450,"sku":"M53 SUMP P","price":242.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305534747.png?v=1778256394","url":"https:\/\/voomisupply.com\/products\/zoeller-m53-sump-p-sump-pump-0-30-hp-automatic","provider":"Voomi Supply","version":"1.0","type":"link"}
