TRIVAC B pumps use oil, injected into the pump chamber, for sealing, lubrication and cooling of the pump. The lubrication system is rated for continuous operation at high intake pressures (max. 1000 mbar abs.). This leads to the capability of being used in a versatile manner from atmospheric down to ultimate pressure. The oil carried with the process gas is separated in the oil box.
A wide range of accessories include various types of exhaust filters capable of trapping fine oil mist, which is then transported with the process gas. The option of adding an oil return system completes the modular TRIVAC B range by supplying the filtered oil back into the pump.
