It is designed for installations where semi-corrosive solvents, acids, alkalis and compatible solutions need reliable transfer or recirculation. The compact 1\/12 HP motor is open and fan-cooled, thermally protected, and supplied with a 6-foot cord and grounded plug for straightforward hookup.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this pump handle corrosive fluids?\u003c\/h3\u003e\n\u003cp\u003eThe 3-MD-SC uses glass-filled polypropylene for the volute, magnet housing and impeller, providing strong chemical resistance for a wide range of semi-corrosive liquids. A seal-less magnetic drive removes the need for shaft seals that typically fail with aggressive fluids, and ceramic shaft and thrust washers add wear resistance.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eWetted parts: glass-filled polypropylene to resist many solvents and acids\u003c\/li\u003e\n  \u003cli\u003eSeal-less magnetic drive eliminates mechanical seal leakage\u003c\/li\u003e\n  \u003cli\u003eCeramic (99.5% alumina) shaft and thrust washers for durability\u003c\/li\u003e\n  \u003cli\u003eNon-rotating washers reduce shaft wear and alignment issues\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat are the pump’s performance and plumbing specs?\u003c\/h3\u003e\n\u003cp\u003eRated at up to 750 gallons per hour at a 1-foot head, this unit can achieve a shutdown head near 21.9 feet and handles fluids up to 150°F with specific gravity up to 1.1.

It works well where a seal-less design is preferred to cut leakage risk and where moderate flow with compact electrical requirements is essential. Note: always verify chemical compatibility with glass-filled polypropylene and alumina ceramics and install the pump below the liquid level since it is not self-priming.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can the 3-MD-SC pump handle strong acids and solvents?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: It handles many moderately corrosive chemicals compatible with glass-filled polypropylene and alumina ceramics; always check specific chemical compatibility first.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Is this pump self-priming or submersible?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No — the 3-MD-SC is in-line and not self-priming; install it below the liquid level for correct operation.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Little Giant","offers":[{"title":"Default Title","offer_id":56805820367188,"sku":"B0002APPCG","price":400.83,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1063\/2652\/4244\/files\/little-giant-3-md-sc-front-view.jpg?v=1786810558","url":"https:\/\/gardenluxe.co.uk\/products\/little-giant-magnetic-drive-chemical-pump-3-md-sc-115v-750-gph-seal-less-corrosion-resistant","provider":"Gardenluxe Uk","version":"1.0","type":"link"}
