The company has expanded its family of Series PL™ in-line circulators. The PL-55 delivers high head performance while the PL-75 provides the higher flow rates often required in larger systems, the company says. The circulators feature an advanced, close-coupled, dry motor design that prevents system contamination problems, and the XLII® bearing system, which provides maintenance-free, permanently lubricated bearings, says the company. The close-coupled design increases pump life and efficiency, and can handle difficult water conditions, the manufacturer says.
