nash_elmo nash_elmo Liquid-Ring Vacuum Pumps

nash_elmo nash_elmo Liquid-Ring Vacuum Pumps Oil-Free, in Monoblock and Close-Coupled Design 2BV2 2BV5 2BV6 General nash_elmo 33mbarA(% ) 80mbarA 10mbarA, nash_elmo 2BV 2BV2 2BV5 2BV6 2BV2 2BV5 ( IP5)2BV6 nash_elmo vacuum pumps are suitable for evacuating gases and wet vapours down to inlet pressures of 33 mbara ( % vacuum ). All these vacuum pumps are supplied with built-in cavitation protection. For longterm operation below 80 mbara the cavitation protection should be connected for protecting the pump. An inlet pressure of 10 mbara can be achieved by connecting a gas ejector (see accessories). The gas ejector can be mounted directly onto the vacuum pump. The 2BV nash_elmo vacuum pumps consists of 2BV2,2BV5 and 2BV6 series. The 2BV2, 2BV5 series are especially space saving units in monoblock design (degree of protection IP5).The 2BV6 range is in closecoupled design with drive motor.
