In the CLAWVAC, a pair of claw rotors rotates completely contact-free and wear-free in the cylinder. The main difference between the CLAWVAC and conventional claw pumps is the choice of materials. Stainless steel rotors and the vacuum chamber with a corrosion-resistant coating prove their worth even under very tough process conditions and contribute to the reliability of operation.
