The Berkeley CP/CB series of centrifugal pumps are well-suited for general water systems and use as sprinkler pumps in homes, farms, and light industry. The CP/CB series pumps are constructed of cast iron with both medium and high head models available. These series of centrifugal pumps feature a heavy-duty motor with easy service design, a four-position discharge, and a drain port that provides for easy winterizing. All models come with carbon/ceramic Buna-N mechanical seals and includes a replaceable wear ring. The CP/CB series also features a back pull out design for easy serviceability. The CP series comes with an abrasion resistant Noryl impeller for normal applications with working temperatures up to 140 degrees Fahrenheit. The CB series comes with a silicon bronze impeller and is equipped with shaft seals rated for temperatures up to 225 degrees Fahrenheit. Medium head models deliver up to 110’ of head with capacities up to 140 GPM. High head models deliver up to 140’ of head with capacities up to 90 GPM.
