Pumps vacuum NVR type

NVR — pump lamellar and rotor vacuum pump.

The pumped-over environment: it is intended for pumping from the tight volumes of air, chemically nonaggressive gases and steam-gas mixes which are previously purified of drop moisture and mechanical pollution. The index "D" means that the pump two-level.

Scope: most often pumps NVR of this type use where rather superficial vacuum (100-200 Mbar).

Symbol: 2NVR-0,1D
NVR — the pump vacuum rotor.
2 — number of modification;
0,1 — speed of action (liter/sec).
