Principle of operation

A claw pump consists of two rotors (1 and 2). They turn in opposite directions in a compressor housing (7) without contact observing very tight clearances. They are synchronised via a precision gear. As the claw moves over the suction connection (3) and the axial suction channel inlet (4) the gas is sucked into the compression chamber. As the rotors revolve, the gas moves from the suction side to the pressure side. Then it is compressed by the reduction of the volume between the rotors until the lower rotor uncovers the discharge channel (5). This “internal compression” leads to high differential pressures at efficiencies of more than 60 %. Afterwards the pre-compressed gas is discharged via the pressure connection (6). To remove the heat generated by the compression process, cooling air is sucked in between the compression housing (7) and a silencing cover (8) before it leaves the pump.

Models

C-VLR - Claw Vacuum Pumps

Vacuum up to 50 mbar (abs)

Highly efficient, dry and contact-free. Steady performance curve over the entire operating range. Integrated air cooling without additional cooling medium. Available with optional variable speed drive.
ATEX-compliant versions available upon request. Low maintenance; wide range of applications.

C-DLR - Claw Compressors

Capacity up to 500 m³/hr
Pressure up to 2.2 barg

Highly efficient, dry and contact-free. Steady performance curve over the entire operating range.
Integrated air cooling without additional cooling medium. Available with optional variable speed drive.
ATEX-compliant versions available upon request. Low maintenance; wide range of applications.

C-KLR - Claw Combination Pressure - Vacuum Pumps

Capacity up to 133 m³/hr
Pressure up to 700 mbarg
Vacuum up to 600bar (abs)

Vacuum and pressure operating points are virtually independent of each other with excellent flow capabilities. Integrated air-cooling without the need for water cooling. Integrated after cooler for low temperature compressed air delivery. Integrated air cooling without additional cooling medium and built-in compressed air after-cooler lead to low exhaust temperature.

New model - The smart choice - VLU Vacuum pump

Capacity up to 700 m3/hr
Vacuum up to 30 mbar (abs)

High efficiency, dry and contact free compression claw vacuum pumps, fitted
as standard with flange motor, air cooling by integrated fan, silencing hood,
fine mesh filter, vacuum non-return valve on suction side are standard.
