CD300M
The Godwin CD300M Dri-Prime pump is a 12" (300mm) centrifugal trash pump perfect for your biggest jobs. Offering flows to 6,000 gallons per minute (380 liters per second), discharge heads to 200 feet (60M), and solids handling to 3-3/4" (95mm) in diameter, the CD300M moves large volumes of water and provides automatic self-priming to 28 feet (8.5M). For intermittent flows, the double high pressure mechanical seal means the CD300M 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 CD300M is the pump that does it all.
- Direct drive automatic priming 12" (300mm) high volume centrifugal pump with vacuum priming compressor mounted to a diesel engine. Also available in electric drive or as bare shaft pumpend.
- Extensive application flexibility — handles raw sewage, sludges and liquids with solids up to 3-3/4" (95mm) in diameter.
- Continuously operated “Godwin” air ejector priming device requiring no form of periodic adjustment or control.
- Compact design — Pump is direct coupled to engine flywheel for increased reliability.
- Underslung side discharge for easy pipe connection.
- Double, high pressure mechanical seal with high abrasion resistant silicon carbide interfaces. Oil bath immersion for dry running.
- Skid base incorporating integral overnight running fuel tank.
- Simple maintenance — normally limited to checking engine oil, compressor oil and seal lubrication.
- Standard Caterpillar C-9, Caterpillar 3126B or John Deere 6081AF engine. Also available with a variety of other engines including Cummins and Deutz.
- Balanced unit with centralized lifting bracket for easy handling.
