CD250M
An extremely rugged pump, the 10" (250mm) CD250M Dri-Prime pump is capable of flow rates to 3600 gpm (227 l/sec.), total dynamic heads to 180' (54.9 meters), and solids handling capabilities up to 3-1/8" (79mm) in diameter. The CD250M also features the unique Godwin high pressure oil bath mechanical seal that allows for indefinite dry running, perfect for intermittent flow applications. All of these features come standard on a highly maneuverable highway trailer or compact skid for convenient use.
