The DRY C and DRY CR pumps are dry pumps with two claw-shaped rotors which are running with synchronized rotation by means of a pair of gears.
The compression chamber is free of lubricating or sealing fluids.
The gears are oil bath type and the same oil is used to lubricate the bearings. The oil sump is separated from the compression chamber by labyrinth seals.
Cooling is guaranteed by a fan.
The electric motor is flanged and connected to the lower shaft with a coupling.

DRY C 100 up to 150 mbar (abs.)
DRY C 250 - 300 up to 200 mbar (abs.)
DRY CR 60 up to 100 mbar (abs.)
DRY CR 150 - 400 - 500 - 1000 up to 200 mbar (abs.)
