CD225M
The 8" (200mm) CD225M Dri-Prime is an extremely rugged pump, capable of flow rates to 3200 gpm (726.4 M3/hr.), total dynamic heads to 180 feet (54.9M), and solids handling capabilities up to 3-1/8" (75mm) in diameter. The CD225M 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.
- Close mounted arrangement carrying pump and vacuum priming compressor mounted to a diesel engine or electric motor.
- Pumpend available in cast iron, stainless steel and other hardened materials.
- Extensive application flexibility — will handle raw sewage, slurries and liquids with solids up to 3-1/8" (75mm) in diameter.
- Continuously operated “Godwin” air ejector priming device requiring no form of periodic adjustment or control.
- Dry running, high pressure oil bath, mechanical seal with high abrasion resistant silicon carbide interfaces.
- Solids handling swing check Non Return Valve.
- Compact unit mounted on a skid base or two wheeled highway trailer both incorporating integral overnight running fuel tank.
- Simple maintenance — normally limited to checking engine and seal cavity oil levels.
- Standard John Deere 4045T or Caterpillar 3054TA engine. Also available with other diesel engines or electric drive motor.
- Silenced units can be supplied.
- Balanced unit with centralized lifting bracket for easy handling.
