Liquid ring vacuum pump
The motors are supplied as standard for the input voltage ranges of 50 and 60 Hz
and for the protection category IP55 as well as approbated for UL and CSA.
Vacuum ATEX-pumps with 2006/42 EG for category 2G are available, too.
Performance curves
General information
Elmo Rietschle vacuum pumps of the model range L-BV2 are suitable for
evacuating gases and wet vapours down to inlet pressures of 33 mbar abs. (97 %
vacuum). All these vacuum pumps are equipped with built-in cavitation protection.
They work cavitation free down to 80 mbar abs. For operation at lower inlet
pressures the integrated cavitation protection should be connected for protecting
the vacuum pump (no external pipes necessary).
The vacuum pumps are particularly space-saving, reliable and robust in their
monoblock design. The reinforced stainless steel shaft, the permanently
lubricated bearings and the ceramic internal coating of the pump housings
prevent wear, corrosion and calcification.
The characteristic curves are based on the evacuation of 100 % saturated air and
an intake temperature of 20 °C. At a suction pressure of 1013 mbar abs. and a
temperature of the operating liquid of 15 °C (water as operating liquid) the
characteristic curves will be achieved. The tolerance is ± 10 %.

All L-BV fulfil the 2006/42/EC (machinery) and 2006/95/EC (low voltage) directives and the EN 60034-1 norm “Rotating electrical machines”. The motors comply with EN 60 034-1 / -2 / -30
(IEC 60034) and thermalclass F. For three phase motors tolerances are +/-10% for fixed voltage motors and +/-5% for voltage range motors. Singlephase machines are designed with a +/5% tolerance. The frequency tolerance is +/- 2 % maximum.

For partial recirculation operation the quantity of the fresh applied
refrigerant can be reduced by circulation of the operating liquid in a
circuit (with discharge liqiud separator and internal recirculation of the
operating liquid, available as accessories). Complete circuit systems LSV available on request.

An inlet pressure of 10 mbar abs. can be achieved by connecting a
gas ejector (see accessories). The gas ejector can be mounted
directly onto the vacuum pump.
