For the operation of any of the FSM machines, reliable components and assemblies are required that can withstand loads for at least 24 hours.
This category includes the electrode insertion chamber and the unit that performs degassing of this unit-pumps of the NVR group.
Optionally, the equipment FSM is equipped with VRD pumps.

The pumps for the electrode insertion chamber are two-stage rotary vane vacuum pumps, the advantages of which are high reliability, low noise and high vacuum.
For the electrode insertion chambers of any of the FSM machines, both standard NVR-5 models and more productive versions of VRD-4, VRD-8 or their technically equal analogues are used.

Pumps of this type provide the possibility of connection via KF or ISO flange connections.

The pumping equipment of this type is compact, and can be located on the basis of the FSM machine.
Also, optionally, the pumps for the electrode insertion chamber are equipped with a device that is responsible for preventing vapor condensation in the working chamber and maintaining its cleanliness.
