Designed specifically for the SRU family’s 4-series, this rotorcase works with SRU-4N and SRU-4W variants and is a key wear component in the pump head, pairing with the rotor case cover, rotors, rotor nuts, shafts, gearbox and shaft seals to deliver the SRU’s positive-displacement, low-shear transfer of process fluids. The rotorcase interfaces are manufactured for corrosion resistance, with configurations commonly specified in EN 1.4409 (CF-3) or AISI 316L, enabling compatibility with a wide range of hygienic, high-purity fluids across dairy, food and beverage, biotech, pharmaceutical and chemical applications. Its design supports a drainable pump head and defined front-cover seal compression, contributing to reliable sealing and uptime during routine cleaning and maintenance. As a direct replacement part within the SRU-4 lineage, the rotorcase helps preserve the pump’s geometry and performance without replacing the entire unit, making it a targeted service component for sustaining SRU-4 operation. \u003c\/p\u003e\u003c\/div\u003e","brand":"ALFA","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51657200206126,"sku":null,"price":116.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_beee402f-177e-43bb-a8d0-31419f0da17c.jpg?v=1769466802","url":"https:\/\/plgautomation.com\/products\/alfa-laval-sru-4-rotorcase-for-sru-rotary-lobe-pump","provider":"PLG Automation ","version":"1.0","type":"link"}
