Design characteristics

• optimized inlet and outlet cross section for gentle product feeding combined with optimized filling degrees
• leakage gas nozzle integrated into housing
• solid temperature range from -10 to +60°C and ambient temperatures from -10 to +40°C for standard design; other temperature ranges according to customers' requirements
• minimum leakage gas volume due to optimum execution of gaps and 12 chamber rotor
• circular inlet and outlet flange – no transition pieces required
• mounting devices for gear motor, junction box and if necessary for solenoid valves and supporting construction directly at housing
• externally located ball bearings with lifetime lubrication; material outlet opening between shaft sealing rings and bearing
• labyrinth sealing ring, for powdery products with purge gas device, preventing material flow into the sealing area
• free shaft end of rotor visible, enabling a visual control of the sense of rotation and rotor
• speed chain drive with adjustable chain tension roller
• closed chain guard made of aluminum´
• EC conformity declaration according to ATEX regulations 94/9EG
  
  

Design

• throughput up to 295 m³/h at a filling degree of 100% under consideration of ATEX regulations
• sizes (rotor diameter in mm) 200 / 250 / 320 / 400 / 500 / 630
• differential pressure up to 1.5 bar (g)

Versions

• connecting dimensions of flanges according to DIN PN 10, ANSI 150 or works standard
• special design, such as other materials of construction, quick-cleaning devices and rotor chambers upon request
• pressure shock resistant and flame proved
• for high temperatures, heating or cooling of housing possible
