C-Series Claw

Product catalog summary

Introduction
The C-Series Claw technology offers efficient and economical vacuum or compressed air generation through internal compression, leading to significant energy savings compared to traditional designs.

Performance Spectrum
The C-VLR claw vacuum pumps and C-DLR claw compressors achieve ultimate pressures of up to 50 mbar (abs.) for vacuum and up to 2.2 bar for pressure. Combination pressure-vacuum pumps provide underpressure up to -0.6 bar and overpressure up to +1.0 bar.

Innovative Claw Technology
The C-Series features high precision, contact-free claw rotors synchronized by precision gears, achieving dry and wear-free compression. The design includes special seals and an overhung rotor design for sizes up to model 300. Gas-tight and explosion-proof versions are available, including ATEX compliant models.

Advantages

High efficiency
Dry, contact-free operation
Process safety and reliability
Cooling air discharge capability
Robust housing
Variable speed drives
Low sound level
Patented triple lobe rotors
Combined pressure and vacuum in one stage
ATEX compliance

Product Overview
C-VLR ZEPHYR Claw Vacuum Pumps: Capacities from 60 to 1,000 m³/h, maximum vacuum up to 50 mbar (abs.), dry and contact-free operation, integrated air cooling, optional variable speed drive, ATEX compliant.
C-DLR ZEPHYR Claw Compressors: Capacities from 60 to 600 m³/h, maximum pressure up to 2.2 bar, dry and contact-free operation, integrated air cooling, optional variable speed drive, ATEX compliant.
C-KLR ZEPHYR Claw Combination Pressure-Vacuum Pumps: Capacities from 80 to 140 m³/h, vacuum up to -0.6 bar, pressure up to +1.0 bar, integrated air cooling, low maintenance.

Technical Specifications
The C-Series operates on a static compression system with internal compression achieved by volume contraction. The claw pumps consist of two rotors turning in opposite directions without contact, synchronized by precision gears. This design leads to high differential pressures with efficiencies over 60%.

Claw vacuum pumps, compressors and pressure-vacuum pumps Our dry running C-Series generates contact free vacuum or compressed air efficiently and economically due to the principle of internal compression. This leads to considerable energy savings compared to the traditional rotary lobe design without internal compression. C-VLR ZEPHYR Vacuum pump Wide spectrum of performance With the C-VLR claw vacuum pumps and C-DLR claw compressors the following ultimate pressures are attainable during continuous operation: vacuum up to 50 mbar (abs.) and pressure up to 2.2 bar. Combination pressure-vacuum...

Technical specifications Vacuum range in mbar (abs.) Operating principle Much like rotary vane and rotary lobe pumps, the claw compressors and vacuum pumps of the C-Series are based on a static compression system. In contrast to rotary lobes, compression happens internally by volume contraction. 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...
