Piston Pumps Supreme Performance, Superior Hygiene, and Simpler Service
Alfa Laval’s new DuraCirc circumferential piston pump offers high efficiency, reliable operation and meets the EHEDG guidelines for hygienic processes across the dairy, food, beverage, confectionery, and home-personal care industries.
Performance, hygiene and simpler service are essential to hygienic processes. Yet manufacturers across the dairy, food, beverage, confectionery, and home-personal care industries must often compromise on one essential to achieve another. Not anymore.
The new Alfa Laval DuraCirc circumferential piston pump delivers it all: robust design, high efficiency, and reliable operation; hygienic assurance with EHEDG as well as 3-A certification as standard; and, ease of maintenance, states the company. The new circumferential piston pump is a gamechanger. It’s everything users want, all in a single pump – the perfect balance of supreme performance, superior hygiene, and simpler service, adds the firm.
Engineered for durability, reliability and efficiency, the piston pump extends the boundaries of process performance. With a robust construction, the pump range features a high efficiency design, wide performance envelope and low net positive suction head (NPSH) requirement. With flow rates up to 150 m3/h (660 gpm), the pump is capable of handling operating pressures up to 40 bar (580 psi), which is 15 % higher than all other circumferential piston pumps available today, mentions the company. Optional ports make it easy to replace existing pumps from Alfa Laval and other brands with the DuraCirc, without having to adapt pipework.
Certified to meet EHEDG guidelines and 3-A Sanitary Standards, the pump assures process integrity and product quality. For a crevice-free design with no dead zones, all product-wetted elastomers are made of FDA-conforming materials and profiled and defined compresssion as standard; this reduces contamination risks and cuts both cleaning time and costs, opines the firm.
Seal positioning with seal faces fully immersed in the pumped media further boosts cleaning efficiency. Heavy-duty bearings support rigid shafts located in a solid stainless steel gearcase; this reduces shaft movement, minimizing pump-head contact and therefore the risk of media contamination. Additionally, the all-stainless-steel construction, suitable for hygienic washdown, ensures a cleaner environment, comments the company.
Among the pump’s innovative design features: a truly front-loading single seal; long-lasting bearings; a single, long-life gearbox lubricant; external shimming; and fully interchangeable components. These eliminate complex, costly, time-consuming rebuild procedures, simplifying maintenance, states the firm.
