DuraCirc® from Tetra Pak solves the riddle of performance, hygiene and maintenance
Traditional circumferential piston pumps (CPPs) are usually limited because they offer:
- High volumetric efficiency, but with limited cleanability
- Improved cleanability at the expense of performance
- Hygiene + efficiency, but with more complex maintenance requiring more downtime
Now you don’t have to compromise or make trade-offs between these key parameters, because DuraCirc combines the best of all three worlds.
Performance and hygiene benefits
Designed for high performance and durability
DuraCirc has class-leading flow and pressure capabilities that yield a high volumetric efficiency. Low NPSHr significantly reduces the risk of harmful cavitation, and our Uni-fit option allows retrofitting to third-party equipment. Plus flow rates up to 150 m3 /hr and maximum operating pressure up to 40 bar – 15% higher than anyone else’s.
Outstanding hygienic design and certifications meet exacting standards
DuraCirc complies with a wide range of international hygienic, safety, quality control and environmental standards. Its stainless-steel construction eliminates crevices or product/bug traps and reduces the risk of contamination, with easier cleaning and more efficient CIP. It features profiled compression elastomers, optimized seal location, complete drainability in a vertical port configuration, and FDA-conforming lubricant.
Keep it flowing: fast, easy cleaning and maintenance for minimal downtime
Everything is easy when it comes to maintenance, with a truly front-loading, self-setting single seal, allowing quick and easy changes without removing the pump. Rotor refitting is equally quick and easy, with no need to re-measure head clearances or reset timing. Only a single lubricant is required (not two), with an oil change interval of 3,000 hours. Add long-life bearings, interchangeable parts, and external adjustment shimming, and you have an uptime champion.
Optimise pump performance with condition monitoring
Your assets are talking. We help you listen. Improve your operations with pump performance data for deeper insights with Asset Health Monitoring with Condition Monitoring by Alfa Laval. You keep your operations efficient and cost effective, while preventing unplanned downtime thanks to understanding the running condition of your pumps and whether service or maintenance is required. You get real-time data turned into actionable insights with our OEM (Original Equipment Manufacturer) expertise to continuously optimise pump performance. Access it all on a secure, user-friendly dashboard and detect potential anomalies earlier, validate corrective actions through data, and confirm optimal pump health. A single condition monitoring notification, for example, prevented pump failure and saved a UK beverage producer the product loss of 288,000 bottles – enough to payback their entire investment in the solution and their first year of analytics subscription.
