TRIVAC® E-Two-Stage Oil-Sealed Rotary Vane Vacuum Pump

The TRIVAC® E pump is an oil-sealed vacuum pump operating according to the rotary vane principle. Oil which is injected into the pump chamber is used for sealing, lubrication and cooling purposes. New customers’ requirements as well as increased environmental requirements gave rise to the further development of the successful range of TRIVAC® B pumps. The result is the TRIVAC® E rotary vane vacuum pump. Beyond the usual quality and reliability of the B series pumps, the TRIVAC® E pump offers improvements in the area of quieter operation, smaller size and improved service-friendliness. The intake and exhaust ports are equipped with small flanges. Besides standard voltages and frequencies, Oerlikon Leybold Vacuum offers world motors, which are specially required by OEMs. The TRIVAC® E pump includes also a set of accessories which also fit the TRIVAC® D 4 - 16 B pumps.
