What makes the DuraCirc Aseptic ideal for sterile processing?

The Alfa Laval DuraCirc Aseptic rotary lobe pump was specifically designed to meet the stringent requirements of aseptic processing environments. The pump's most distinctive feature is its steam barrier capability at all product-to-atmosphere interfaces, creating a protective environment that prevents contamination during operation. This design approach enables truly sterile pump operation—critical for dairy processing and sensitive food applications.

How does the DuraCirc Aseptic pump maintain hygiene standards?

Beyond its steam barrier technology, the pump features a hygienic construction that meets and exceeds industry standards. All product-wetted steel components are crafted from W. 1.4404 (AISI 316L) stainless steel with a mechanical surface finish of Ra ≤ 0.8, ensuring smooth surfaces that resist bacterial adhesion. Both EHEDG and 3A certifications validate the pump's hygienic design, translating to reduced cross-contamination risk and shorter CIP cycle times. The double-wing rotary lobes are manufactured from special wear-resistant alloy, providing extended service life even in demanding applications.

What operational benefits does the DuraCirc Aseptic deliver?

The DuraCirc Aseptic stands out for its high volumetric efficiency, allowing for optimized pump selection and improved process yields. This efficiency directly translates to reduced investment costs and energy savings during operation. The pump's robust construction features a strong gearbox with integrated shafts of larger diameter and optimally positioned high-performance bearings, minimizing the risk of pump head contact during operation. These design elements contribute to extended operational life, with the pump being backed by Alfa Laval's extended 3-year warranty covering all non-wearing parts.

How is maintenance simplified with the DuraCirc Aseptic?

Maintenance considerations were central to the DuraCirc Aseptic's design philosophy. The pump features full component interchangeability without complicated maintenance procedures, reducing downtime during service interventions. The bearings are designed for long service life and require only a single lifetime lubrication—eliminating the need for regular relubrication. These design features significantly reduce total cost of ownership while ensuring consistent performance throughout the pump's operational life.

What connection options are available for processing systems?

The DuraCirc Aseptic offers exceptional flexibility when it comes to system integration. Available in five different capacities, the pump can be configured with either vertical or horizontal ports to adapt to various installation requirements. Connection sizes range from 50mm for the DuraCirc Aseptic 42 model up to 150mm for the DuraCirc Aseptic 73 model. Seal connections are available in either BSP/G or NPT threading options, with sizes of 1/8" for the DuraCirc Aseptic 42 model and 1/4" for the larger 53-73 models. Port and front cover connections across all models maintain consistency with BSP/G 1/8" or NPT 1/8" options.
