LEYBOLD TRIVAC PUMPS

Leybold TRIVAC B vacuum pumps are designed for reliability and long service-life in mind. Directly linked to the motor via an elastic coupling element to ensure that the pump runs evenly and smoothly. With a type B 14 flanged motor screwed to the housing of the coupling. All pumps include a gas ballast valve as well as an inner section which may be exchanged without special tools or any special knowledge.

Trouble-free operation even at 1000 mbar intake pressure is ensured by a built-in oil pump, providing force-feed lubrication of the bearings from where a minimum amount of lubricant is fed to the compression and expansion chambers to ensure lubrication of the sliding vanes.

To minimize surface corrosion all components are protected by eliminating non-ferrous metals. The oil box, intake and exhaust line are made of aluminum and only solvent-resistant sealing materials are employed.
