A new model added to this pump range

Following the earlier introduction of the CR 185 and CR 215 pumps, this company recently added the CR 255 pump (photo), with flow range capacities up to 240, 280 and 320 m3/h respectively. The new hydraulic design improves everything from impeller and 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. 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, says the company. The shaft seal of the CR pumps is developed in-house and is available in various material combinations to suit different liquid, pressure and temperature requirements. Thanks to its balanced design, the CR seal can withstand a great amount of pressure and can expect a longer service life compared to other large pumps. The pumps also are designed to reduce the risk of cavitation and increase the robustness and lifecycle of the pump. — Grundfos, Bjerringbro, Denmark
