NVR type pump -a plate-roting vacuum pump.
pumped environment: designed for pumping from hermetic volumes of air, chemically non -aggressive gases and steam -gas mixtures previously cleansed of drip moisture and mechanical pollution. The d index means that the pump is two -stage.
Scope: most often NVR this type is used where a rather shallow vacuum (100-200 MBAR).
.
Condition: 2NR-0.1D
NVR - Vacuum rotor pump.
2 - modification number;
0.1 - speed of action (liter/s).
