Alfa Laval 9630046124 Plain Rotorcase Cover For SRU4 SRU-4 Rotary Lobe Pump

Alfa Laval 9630046124 Plain Rotorcase Cover is a dedicated spare part for the SRU4 SRU-4 rotary lobe pump, forming the plain upper rotorcase cover that seals the pump head and provides a mounting interface for rotor components. Specifically engineered for SRU4 pumps, this cover complements the standard rotorcase seal arrangement and supports straightforward service and maintenance when replacing worn or damaged rotorcase parts. Used in hygienic processing environments, SRU pumps are favored for gentle handling of sensitive fluids, and the rotorcase cover helps maintain cleanability and sanitary design. The part is cataloged under 9630046124 in Alfa Laval's SRU4 spare-parts ecosystem, alongside other covers—some variants include a relief valve accessory for systems that require overpressure protection. In practice, this plain cover is chosen when a valve-free rotorcase cover is required, and it is compatible with SRU4/SRU-4 configurations. For installation, follow Alfa Laval's maintenance guidelines to ensure proper fit and seal compression and to maintain pump performance in demanding applications.
