Standard-pressure compact feeder
The CFH standard-pressure rotary feeder is mainly used for the conveying and discharge of bulk material in pneumatic conveying systems. Its special design allows the valve to be used at differential pressures up to 1.5 bar (g) while maintaining optimal leakage values.
Characteristics
- Extremely wide range of outputs due to seven available sizes (200–750)
- Gentle distribution of bulk material at ideal filling factors, achieved by optimized inlet and outlet geometry
- Minimal gas leakage due to optimal, customized spacing of the 12-chamber rotor
- Extremely high throughput and output, with high filling range, low overflow and integrated leakage-gas channel
- Durable and low-maintenance in design features and materials selection
- Identical housing shape for all CF valves, from powdered to pelleted bulk materials
- High-quality cast aluminum (hard-coated) housing and bearing plates as standard, available in high-quality cast stainless steel as an option
- High-quality stainless steel rotor
- Integrated leakage-gas nozzles in housing
- Permanently lubricated external rolling bearings. Reject opening between shaft-sealing rings and bearings
- Durable, radial, low-wear sealing system
- Differential pressure between up to 1.5 bar (g), mechanical design pressure from -1.0 to 10 bar (g)
- Mechanical temperature resistance from -20 to 90°C, optionally up to 180°C
- Flange joints bored in accordance with DIN 2501 PN10 FF or ANSI 150 lbs FF
- Declaration of incorporation or declaration of conformity in accordance with the Machinery Directive, EC type examination certificate and declaration of ATEX conformity available
