It features a 1\/2 inch by 1\/2 inch shaft configuration and includes a heavy duty spring for reliable engagement. This coupler is designed to connect the motor shaft to the pump shaft, transferring rotational power with minimal slippage or vibration. It is compatible with LD3, HD3, S-45, and S-46 pump models, making it a direct replacement part for technicians servicing those specific units. Cast iron construction gives this coupler excellent strength and resistance to wear under continuous mechanical stress. The heavy duty spring included with the ssc-780 helps absorb shock loads and compensates for minor shaft misalignment, which extends the working life of both the coupler and the connected pump assembly. Plumbers, HVAC technicians, and pump service professionals rely on pump couplers like the ssc-780 to restore proper function to water pumps, circulation pumps, and sump pump systems. When a coupler wears out or cracks, the pump loses drive efficiency and can fail entirely. Replacing it with a matched OEM-specification part like this one ensures the pump operates at rated performance. The 1\/2 inch shaft size is a common standard in light to medium duty pump assemblies, and the cast iron body provides a rigid, durable connection that holds up in wet and high-cycle environments. Technicians should verify shaft diameter and compatible pump model numbers before installation to ensure a proper fit. This part ships ready for direct installation with no additional hardware required beyond what is included.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eCast iron construction for strength and long service life under continuous use\u003c\/li\u003e\n\u003cli\u003e1\/2 inch by 1\/2 inch shaft size for direct fit on compatible pump assemblies\u003c\/li\u003e\n\u003cli\u003eIncludes heavy duty spring to absorb shock and accommodate minor shaft misalignment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe ssc-780 cast iron pump coupler is a direct replacement part for LD3, HD3, S-45, and S-46 pump models, delivering reliable shaft coupling with a heavy duty spring and durable cast iron body.\u003c\/p\u003e\u003ch3\u003eProduct Information\u003c\/h3\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: STRAINER SCREEN AND CYLINDER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ssc-780\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Type\u003c\/strong\u003e: Coupler\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShaft Size\u003c\/strong\u003e: 1\/2 inch x 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Pump Models\u003c\/strong\u003e: LD3, HD3, S-45, S-46\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUsed On\u003c\/strong\u003e: Pump\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Heavy Duty Spring\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STRAINER SCREEN AND CYLINDER","offers":[{"title":"Default Title","offer_id":51120884154674,"sku":"SSC-780","price":49.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/304881680.jpg?v=1777742332","url":"https:\/\/voomisupply.com\/products\/strainer-screen-and-cylinder-ssc-780-cast-iron-pump-coupler-1-2-inch-x-1-2-inch-shaft-for-ld3-hd3-s-45-s-46","provider":"Voomi Supply","version":"1.0","type":"link"}
