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.
