CD400M
Godwin’s CD400M Dri-Prime is an 18” x 18” (450mm x 450mm) centrifugal trash pump perfect for your biggest jobs. Offering flows to 10,000 gallons per minute (631 l/sec.), discharge heads to 150’ (46M), and solids handling to 5” (125mm) in diameter, the CD400M moves large volumes of water and provides the ease of automatic priming to 28 feet (8.5M). For intermittent flows, the double high pressure mechanical seal means the CD400M can run dry indefinitely without damage. And the underslung discharge flange makes pump connections easy and efficient. When your job calls for both high volume and high head, the Godwin CD400M is the pump that does it all.
