The vacuum pump of the model range 2BV5 are especially space-saving in their
monoblock design. They are available in cast iron (standard color RAL 9006) and
in stainless steel (all stainless steel parts are pickled and passivated). The motor
is painted as standard in RAL 9006.
The characteristic curves are based on the evacuation of 50 % 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 %.
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.

General information
Elmo Rietschle vacuum pumps of the family L-BV5 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).

2) Measuring surface sound pressure level acc. to EN ISO 3744, measured with an equivalent unit at a distance of 1 m. The pump is throttled to an average suction pressure, with piping
connected, but no relief valves fitted, tolerance ±3 dB (A).

Voltage range
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 thermal class F. Voltage tolerances for three phase motors are +/-10%. The frequency tolerance is +/- 2 % maximum. Service factor (SF) and motor efficiency according NEMA
MG1-12.

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.
