Introducing the Alfa Laval DuraCirc a revolutionary circumferential piston pump delivering the perfect balance of; Supreme Performance Superior Hygiene Simpler Service Supreme Performance Engineered for durability Engineered for durability, reliability Engineered for durability, reliability and efficiency to extend the boundaries of your performance High volumetric efficiency design via reduced slip though close clearances, aids optimal pump selection, ensuring reliable operation, whilst also increasing product quality and process yield. With a comprehensive range of 13 models, having a pressure capability up to 580 psi and flow rates up to 660 gpm provides for cost effective pump selection across a broad application scope Featuring a durable, robust, reliable design, with a strong gearcase, incorporating increased diameter shafts, supported by optimally positioned heavy duty bearings reduces shaft deflection and axial movement. This allows close clearances, minimising risk of pump head contact, maintaining process continuity. Advanced port and pump head geometry gives a very low NPSHr characteristic, significantly reducing cavitation risk. The DuraCirc “Uni-fit” option allows easy direct replacement of other major brands into existing process system designs reducing installation cost. Superior Hygiene Safely meeting industry hygienic demands, assuring the integrity of processes and product quality Having globally recognised approvals including EHEDG and 3A, as well as using FDA conforming materials, reduces contamination risk and CIP cycle time, increasing process uptime, whilst cutting cleaning costs Along with defined compression product wetted profiled elastomers throughout, eliminates all dead zones, ensuring efficient cleaning, preventing cross contamination risk Uniquely designed sealing, with faces located directly in the media flow path, allows for increased cleaning efficiency Having a durable, robust, reliable pump design, utilising a solid stainless steel gearcase and optimally positioned heavy duty bearings supporting a rigid shaft, reduces shaft movement, minimising pump head contact, thereby risk of media contamination. Featuring an all stainless-steel construction, suitable for hygienic washdown, ensures a cleaner environment Simpler Service During operation many traditional circumferential piston pumps suffer rotor wear due to rotor case contact, even at relatively low operating pressures leading to increased maintenance cost and risk of product contamination With the Alfa Laval DuraCirc Hi-Life rotor this is no longer an issue The unique design allows operation up to pressures of 360 psi without component contact significantly reducing both maintenance cost and ensuring product integrity Innovative design makes maintenance faster and easier, increasing operational uptime Incorporating a truly front-loading single seal that can be replaced quickly and simply, without pump removal from process line, reduces process downtime Missing splines allow for unique rotor positioning, enabling easy rotor re-fitting, reducing maintenance time Using a single gearbox lubricant, with extended service life, maintains continuous operation Additionally, long life bearings negate the need for any complex maintenance, reducing life-cycle cost Factory set timing and shimming further simplifies standard preventative maintenance, making difficult gearbox re-builds, when changing key components, unnecessary. All product wetted parts are fully interchangeable, without time consuming and complex re-build procedures, emphasising its simpler service features The Alfa Laval DuraCirc offers a variety of product specification options to match an individual user’s process requirements Incorporating 5 seal options, including single, single flush and double mechanical seal, as well as o-ring and flushed o-ring, together with a variety of seal faces and elastomers, provides sealing solutions for a wide range of applications Available in either horizontal or vertical port orientation, provides flexibility to suit process requirements For applications involving very high viscosities, a rectangular inlet option is available to assist with media entry into the pumping chamber. An optional aseptic variant, whereby all external media interfaces can be protected by a steam barrier, allowing for use in sterile applications Where pre-heating or cooling of pumped media is required, an optional heating/cooling jacket can simply be fitted onto the existing rotor case To protect the pump and process, an Alfa Laval CM condition monitor can be fitted, to avoid unplanned maintenance Offering Supreme Performance, Superior Hygiene and Simpler Service, the Circumferential Piston pump with no more compromises, the Alfa Laval DuraCirc. The future of pumping is on the move.
