Grundfos Suction Diffusers are designed to streamline flow into the pump's suction side, ensuring optimal performance and extending pump lifespan. They provide a uniform flow pattern, ensuring a stable Net Positive Suction Head (NPSH), and incorporate a cylindrical strainer to prevent impurities from entering the pump. This design allows for installation in confined spaces without the need for long pipe bends, saving floor space and simplifying system layout.
