- Model CD150M - Automatic Centrifugal Pump



The Godwin Dri-Prime 6' (150mm) CD150M automatic priming centrifugal pump is clearly the backbone of the temporary portable pumping industry. With solids-handling to 3' (75mm) in diameter, maximum flows of 1700 gallons per minute (107.3 l/sec.) and 160 feet (48.8M) of total dynamic head, and indefinite dry-running capabilities, the CD150M can be found in a wide variety of applications from straight dewatering to sewage bypassing. Mounted on a highway trailer, the CD150M is the most maneuverable and versatile portable pumping system available, making it a favorite of contractors, municipalities, industry and environmental companies across the country.
