- Model CD80M - Automatic Centrifugal Pump



The Godwin Dri-Prime 3' (75mm) CD80M automatic priming centrifugal pump is a compact and highly maneuverable portable pumping system that can deliver a maximum of 450 gallons per minute (28.4 l/se.c) and total dynamic heads to 93 feet (28.3M). The CD80M comes standard mounted on a highway trailer or skid mounted, and both include an integral 30 gallon (113.5 liter) fuel tank for overnight running capabilities. A recessed impeller model is also available for increased solids handling. Indefinite dry running is no problem due to the unique Godwin oil bath mechanical seal design. Solids handling, dry-running and portability make the CD80M the perfect choice for small dewatering and bypass applications.
