Oil sealed vacuum systems

NEO D Systems standard equipment

Based on the longstanding experience in the design and manufacture of vacuum pump systems, Leybold offers standardized pump systems which will match most applications – the NEO D pump systems. NEO D pump systems excel by being compact, reliable and service-friendly.

The two to three stage oil sealed NEO D pump systems are equipped with NEO D as fore vacuum pump combined with RUVAC WA(U), WS(U). In single-flow arrangements suction speeds of 250 to 501 are possible. Higher suction speeds can be achieved by adding pumps systems in parallel. The achievable working pressure depends on the number of pump stages and of pump systems in parallel.

The pump systems are equipped as standard with 400 V, 50 Hz und 460V, 60Hz three phase motors. Motors for special supply voltages, special mains frequencies or explosion protected pumps are available.
