The PVR NEXT Generation portfolio has a new dry claw vacuum pump:
DRY C 157. It is an innovative product that works in contaminant-free environments and performs better than standard pumps.
The new design of the DRY C 157 is compact, facilitates disassembly of its components and minimizes pump maintenance.

• The compression chamber is free of lubricants or sealing fluids.

• The gears are oil-immersed, and the same oil provides lubrication for the bearings.
  The oil sump is separated from the compression chamber by labyrinth seals.

• Cooling is provided by a fan.

• The electric motor is flanged and connected to the motor shaft with a coupling.

The DRY C NEXT Generation series pumps are suitable for evacuating closed systems or for operating at a constant absolute maximum vacuum of:

DRY C 157 up to 80 mbar (absolute)
