nash_elmo vacuum pumps are suitable for evacuating gases and wet
vapours down to inlet pressures of 33 mbarA ( 97% vacuum ). All these
vacuum pumps are supplied with built-in cavitation protection. For long-
term operation below 80 mbarA the cavitation protection should be con-
nected 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 IP54).The 2BV6 range is in close-
coupled design with drive motor.

The characteristic curves are based on the evacuation of 100% saturated
air with a temperature of 20 . Discharge pressure is 1013 mbarA, and the
operating liquid is water with a temperature of 15 , tolerance 10%.
The characteristic curves with inlet pressure below 33mbarA are achieved
with the vacuum pump and connected gas ejector ( accessory). For the
operating liquid flow, refer to page 4.
