Since 1937, when Berkeley pumps were first used to irrigate the fertile fields of the San Joaquin Valley of Central California, up-through today's most challenging water transfer projects and residential water flow needs, the name Berkeley has stood for uncompromised quality and proven reliability. As Berkeley has grown, so has its product line. Today Berkeley leads the industry with the most comprehensive product lines available in the industry.
