Grundfos’ CR 255 features a new hydraulic design improves everything from impeller to guide vanes to inlet, discharge port, sleeve, and diffuser, taking current energy efficiency and performance standards for vertical multi-stage inline pumps to the next level, the company notes. To ensure maximum efficiency, the hydraulic design of the new CR range has been optimized to move liquids with as little friction and turbulence as possible, Grundfos points out.
