Ion vacuum pumps NMD-0,016 and NMDI-0,016
Ion pumps NMD-0,016 are used for oil-free extraction of gases and gas mixtures (air) from vacuum systems and creation of high and ultrahigh vacuum. Ion pumps NMD-0,016 are used as a part of vacuum processing equipment.
Diode ion vacuum pumps NMD- 0,016 are not intended for extraction of inert gases and continuous extraction of hydrogen (inert gases and hydrogen can be pumped out only as impurities in chemically active gases with atomic weight higher than 14). Their capacity is reduced if they are used to pump hydrocarbons. Inert gases can be extracted by diode ion vacuum pumps NMDI-0,016.
The pumps are supplied in a moderately cold climate modification category 4 according to GOST 15150. Ion pumps are powered by special power supply units (further – BPM), not included in the delivery package of the pump.
Diode ion pumps NMD-0,016 are manufactured in two modifications of the connecting flange: according to OST 11 868.007 (FO) and according to GOST 26526 (FG).
NOTE: Power supply units BPM for ion the pumps are supplied by a separate order, together with the pump or separately. Key features of vacuum pumps NMD-0,016 and NMDI-0,016 are shown in the table below. Design and basic dimensions of counter flanges of our ion vacuum pumps are shown in the Appendix. Basic specifications of BPM power units recommended for our pumps are shown in with General specifications of ion vacuum pumps.
