Web Exclusive--Multistage Centrifugal Pumps
Grundfos has expanded its small multistage centrifugal pump line, with the introduction of the CR1s, CR1, CR3 and CR5 pumps, providing new sizes with greater flow range. The new pumps provide nominal flow rates from one half-gallon per minute through 45 gallons per minute. The new pumps feature integrated shaft component cartridges, which insure proper assembly of the shaft seal and allow for seal replacement without dismantling the pump, reducing maintenance times from hours to minutes. In addition, the spring is pre-loaded precisely, to ensure the optimal tension between the respective seal surfaces. Cartridges are available in flushed seal, double seal and magnetic drive, operating in temperatures ranging from -40 degrees F to +250 degrees F. www.grundfos.comGrundfos Pumps Corp.
