Claw Vacuum Pumps

Volume Flow 60 – 1,140 m3/hr

Elmo Rietschle, C-VLR ZEPHYR Series, Claw Vacuum PumpsThe C-VLR ZEPHYR series claw vacuum pumps have capacities ranging from 60 to 1,140 m3/hr. The maximum ultimate vacuum at continuous operation is up to 50 mbar (abs).

Part of the dry running C series, the C-VLR ZEPHYR models efficiently and economically generate contact free vacuum thanks to the internal compression principle. This leads to considerable energy savings compared to the traditional rotary lobe design without internal compression.

These highly efficient claw vacuum pumps have a steady performance curve over the entire operating range. They have integrated air cooling without an additional cooling medium and are available with optional variable speed drive.

The C-VLR ZEPHYR series have a wide range of applications and are most commonly found in the; printing and paper, chemical, environmental, industrial, packaging and woodworking industries.

ATEX compliant versions are available upon request.

Key Benefits

  • Innovative claw technology
    The claws of the C series feature an optimised, high precision shape and roll together without contact, synchronised by a precision gear set. Compression is achieved dry and wear free. Special seals separate the compression chamber and gearbox. The claw rotors control the transportation of the medium by opening and closing the inlet and outlet channels. As a result, no sealing fluid is needed within the compression chamber.
  • Low maintenance
    The C-VLR ZEPHYR series claw vacuum pumps require only minimal maintenance.
  • Low sound level
    Like the other machines within the C series, these claw vacuum pumps emit only low sound levels.
