The latest offering in Leybold’s vacuum pumping portfolio brings with it some innovative new features. The CLAWVAC-CP vacuum pump has been uniquely designed for rough industrial applications and is suitable for drying and sterilization processes.

The CLAWVAC-CP comes in three pumping speed classes and is well suited for continuous operation over a wide range of working pressures. The CLAWVAC is particularly effective for challenging applications including particle handling and vapor-contaminated gases. The gearbox is segregated from the pump chamber ensuring that oil does not come into contact with process gases.

The simple yet robust handling of the CLAWVAC can be attributed to the basis of the pump’s design — a pair of claw rotors rotating in the pump stator completely free of contact and wear. The CLAWVAC distinguishes itself from other conventional claw pumps on the market by its materials of construction. The rotors are made of stainless steel and the corrosion-resistant coated vacuum chamber ensure consistently high performance under the harshest operating environments.

Adding to its impressive features is the compact design that provides simple and quick dismantling for maintenance purposes. The rotors can be removed without the need to readjust the synchronization thus allowing quick and easy cleaning of the claws. In addition, the dry, air-cooled operation ensures minimum downtime and maximum performance within a sound-insulated enclosure.

Another notable feature of the CLAWVAC is the modular design capability. Depending on required flowrate, the system can be set up with two to four CLAWVAC pumps in one housing. One pump is speed-controlled, allowing for the exact adjustment of the generated vacuum. The intelligent control activates or deactivates the other fixed speed pumps depending on the vacuum need. This speed control reduces energy consumption, thus reducing overall operating cost.

Single CLAWVAC pumps can provide flowrates of up to 300 m3/hr (1320 US gpm) and modular systems can provide maximum flowrates up to 1144 m3/hr (5037 US gpm). A maximum vacuum pressure of 140 bar can be achieved with the CLAWVAC — CP300 and 150 mbar with the CLAWVAC — CP System.
