The Godwin Dri-Prime 4 inch (100mm) CD100M automatic priming centrifugal pump is a highly maneuverable portable trash pump with flow capabilities to 750 gallons per minute (47 liters per second), total dynamic heads to 115 feet (35 meters) and solids handling to 2 inch (50mm) in diameter. The unique Godwin venturi air evacuation system allows the CD100M to prime from dry conditions with suction lifts up to 28 feet (8.5 meters). Perfect in intermittent flow situations, the CD100M can run dry indefinitely without damage due to the oil bath mechanical seal design. For sewer bypass, general dewatering, and many other applications, the Godwin CD100M with 4 inch (100mm) hoses is a powerful, yet versatile and portable pumping system.
