Setting New Standards of EfficiencyThe Pentair Aurora brand is delivering over a century of innovation for constant peace of mind. The years of experience with design, sales and manufacturing of centrifugal pumps has led to the new generation of the Pentair Aurora® 382B Series. Today’s room space constraints are more challenging than years ago. Pentair Aurora Vertical In-line Pumps are specifically designed for mounting directly in a pipeline and to reduce the space required in a pump room; two pumps fit in the space of one. These modern pumps with a clean, straightforward and updated design were developed with upgraded materials of construction and a simplified offering without limiting ranges of head and capacity requirements. These pumps not only exceed U.S. Department of Energy (U.S. DOE) pump efficiency standards, but also feature shared hydraulics and premium materials as standard offering. The new Pentair Aurora 382B Series offer industry-leading durability and are an easy to maintain solution for your liquid handling needs.
