Claw Compressor

C-Series – Innovative Claw Technology

Pinnacle Industries distributes C-Series Rotary Claw Vacuum pumps and claw compressors for your industrial needs. If you are considering a rotary vane or rotary lobe pump, you should consider claw compressor technology. The Elmo Rietschle claw compressor equipment features optimized, high precision shaped claws that roll together for contact-free vacuum or compressed air. The efficient and economical claw compressor systems achieve expert functionality using the principle of internal compression. The contact-free, frictionless design of the claw vacuum pump and claw compressor offers higher air volume per horsepower. Elmo Rietschle’s C-Series offers energy efficiency with reduced maintenance for industrial vacuum pump and compressor applications. The Elmo Rietschle claw compressor energy savings are evident in comparison to rotary lobe blower designs without internal compression.

Claw Compressors

If you are looking for pressure and volume flow results, an Elmo Rietschle claw compressor will meet your needs. Claw compressors range in capacity from 42 to 353 cfm and can see a maximum pressure up to 32 PSIG for continuous operation. These claw compressors function smoothly with integrated air cooling without the need for water cooling. C-Series claw compressors are available from Elmo Rietschle with optional variable speed drive and ATEX versions are available for biogas or methane compression.

Claw Pressure-Vacuum Pumps

If you are looking for vacuum, pressure and volume flow results, an Elmo Rietschle claw combination pressure-vacuum pump will meet your needs. Pressure-vacuum pumps range in capacity from 57 to 82 cfm and can see vacuum up to 18 in HgV and pressure up to 10 PSIG. Vacuum and pressure operating points are virtually independent of each other with expert flow capabilities and there is no need for water cooling as they function smoothly with integrated air cooling. C-Series claw combination pressure-vacuum pumps are available from Elmo Rietschle with optional variable speed drive.

Pinnacle Industries is your source for the industry’s most reliable claw vacuum pumps and claw compressors from Elmo Rietschle. We have a large selection of Elmo Rietschle claw compressor equipment to handle almost all of your vacuum pump or compressor requirements. You’ll find packaged vacuum systems from Elmo Rietschle utilizing the claw compressor technology for central vacuum system applications.

C-Series Compressors

Operating Principle C-Series Claw Compressor

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.

A claw pump consists of two rotors. They turn in opposite directions in a compressor housing without contact observing very tight clearances. They are synchronised via a precision gear. As the claw moves over the suction connection and the axial suction channel inlet 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. 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. To remove the heat generated by the compression process, cooling air is sucked in between the compression housing and a silencing cover before it leaves the pump.


C-DLR
High efficiency, dry and contact-free compression claw compressor with capacities ranging from 60 to 600 m³/hr (35.3 to 352.9 cfm). Pressure up to max. 2.2 bar at continuous operation. Low maintenance, integrated air cooling without additional cooling medium and suitable for multiple applications. Flange mounted motors comply with DIN EN 60034, have IP 54 protection and insulation class F. The C-DLR can be fitted with a frequency converter so that capacity and pressure can be adjusted exactly to the requirements of the customer. Closed loop operation with inlet and outlet connected to the process is possible. See C-DLR data sheet.

Volume flow:

  • 60 to 600 m³/hr
