Operating Principle of the claw vacuum pump and compressor
The claw vacuum pumps and claw compressors 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.
