A versatile single-stage centrifugal pump suitable for a wide range of applications, including heating, cooling, and industrial circulation.
With a variety of hydraulic components and motor options, the Wilo-Atmos BST single-stage centrifugal pump is suitable for diverse applications such as HVAC, water supply, pressure boosting, and water treatment. It can be used to transport clear, non-abrasive fluids in systems like industrial cooling and cleaning units, as well as for agricultural spraying. Stainless steel hydraulics ensure high corrosion resistance and a long service life. The monobloc design, combined with integrated pump feet, facilitates quick installation while ensuring low-vibration and quiet operation. Modern hydraulics paired with standard IE3 motors deliver excellent energy efficiency.
