Alfa Laval DuraCirc circumferential piston pump

Engineered for durability and efficiency, the DuraCirc circumferential piston pump features a high-efficiency design, wide performance envelope and low net positive suction head (NPSH) requirement. With flow rates up to 150 m³/h, the pump is capable of handling operating pressures up to 40 bar. Optional ports make it easy to replace existing pumps from Alfa Laval and other brands, without having to adapt pipework.

Certified to meet EHEDG guidelines and 3-A Sanitary Standards, the pump has a crevice-free design with no dead zones. All product-wetted elastomers are made of FDA-conforming materials with profiled and defined compression, reducing contamination risks and cutting both cleaning time and costs.

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 gear case, which reduces shaft movement, minimising pump-head contact and therefore the risk of media contamination. Additionally, the all-stainless steel construction, suitable for hygienic washdown, results in a clean environment.

Pump options make the product adaptable, increasing application scope. Available options include a wide range of sealing alternatives, an aseptic model, a heating/cooling jacket, horizontal and vertical mounting, and a rectangular inlet for high-viscosity products.
