-BL2N is installed
L-BL2N = Circulation
vacuum pump
Ready-to-connect liquid-ring vacuum pump built into a separator as well as oth-
er accessories, where applicable, used to generate a vacuum.
The liquid-ring vacuum pump consists of a compressor and a drive.
Drive

synchronous moto
r
Liquid ring Compression principle
Pump part Mechanical part of the liquid-ring vacuum pump without a drive
Inside of the pump Chamber of the liquid-ring vacuum pump used to convey material
Impelle
r
Rotating component for generating pressure within the inner chamber of the
compressor
Gas inlet Position for gas inlet
Gas outlet Position for gas outlet
Substructure Mounting plate, base frame or foundation on which the L-BL2N is constructed
Elastic / rigid When the lowest normal frequency of the system, consisting of the L-BL2N and
substructure, is less than 25% above the rotary frequency of the L-BL2N per
measurement direction, then the substructure is considered to be rigid. All other
substructures are considered to be elastic.
A
ssembly environment Space in which the L-BL2N is set up and operated (this may differ from the suc-
tion environment)
Suction/discharge envi-
ronment
Chamber from which the media to be conveyed is suctioned or in which the me-
dia to be conveyed is expelled (this may differ from the assembly environment)
Reference conditions ▪Ambient temperature and suction temperature: +20°C (+68°F)
▪Ambient pressure: 1013 mbar abs. (14.7 psi abs.)
▪Conveyed media: Air with +20°C (+68°F) and 50% relative humidity
▪Speed 2BL2041–2BL2141: 3000 min-1 (50Hz) and 3600 min-1 (60 Hz) in con-
tinuous operation
▪Speed 2BL2251–2BL2341: 1500 min-1 (50Hz) and 1800 min-1 (60 Hz) in con-
tinuous operation

Term Explanation
V
acuum operation Operation with
- pressure at gas inlet p1< p atm. and
- pressure at gas outlet p2= p atm.
Mobile operation Non-stationary operation
A
nti-clockwise opera-
tion (standard)
The direction of rotation is anti-clockwise when facing the pump cove
r
Cavitation emergence and sudden collapse (implosion) of vapour bubbles in the rotating
operating fluid. During the implosion, noise and extreme pressures occur on very
small surfaces. These forces can destroy the pump over a long period of time
due to surface erosion.
Cavitation area Pressure range in which cavitation occurs if no cavitation protection measures
are taken

Safetyandresponsibility
The manufacturer is not liable for damage caused by the failure to observe these
instructions and the related documents [➙6].
Explanation of warning signs
Warning sign Explanation
Danger that failure to observe the measures could lead to death or serious phys-
ical injuries.
Danger that failure to observe the measures could lead to death or serious phys-
ical injuries.
Danger that failure to observe the measures could lead to minor physical injuries.
Danger that failure to observe the measures could lead to material damage.
Correct use of the equipment
▪should only be used within the limits defined in this documentation:
– Mounting conditions [➙20]
– Permitted conditions for use [➙37]
– Electrical data [➙38]
▪only operate when fully assembled and in a technically perfect condition.
▪Can suction the following conveyed media:
– Air or air-vapour mixtures
– all non-explosive, non-combustible, non-abrasive and non-toxic gasses
and gas/air mixtures, after consultation with the manufacturer
▪is designed to operate with the following operating fluid:
– Water with a pH-value of 6 to 9 and free of solid matter (e.g. sand)
Other operating conditions must be agreed with the manufacturer.
Unauthorised operation
It is forbidden to:
▪Operating in a potentially explosive area (ATEX).
▪Connecting to a potentially explosive area (ATEX).
▪Transporting explosive, flammable, aggressive, unstable, oxydative or poison-
ous materials.
▪Using non-commercial facilities without making adjustments for the additional
requirements.
▪Operating in reverse with sudden/abrupt changes in the direction of rotation.
NOTICE! This results in high drive loads and alternating stresses. The
machine can be destroyed.
▪Use in areas with ultrasound and ionising or non-ionising radiation.
▪Operating outside of the limits defined in this document:
– Mounting conditions [➙20]
– Permitted conditions for use [➙37]
– Electrical data [➙38]

610.00186.40.000 · 11.2017 8 / 40 © Gardner Denver Deutschland GmbH
Working in a safety-conscious manner
Work on running or energised vacuum pumps/compressors can lead to seri-
ous injuries due to body parts being drawn in or crushed or death due to
electric shock.
Work on the L-BL2N at a standstill only and in a de-energized condition.
Pressures and ejected media can cause serious injuries.
1. Depressurise the system before starting work on the L-BL2N.
2. Check that all components are depressurised.
3. Check that no media can escape.
Screws can damage the thread when screwed in repeatedly. This can cause
screwed parts to become lose and lead to severe injuries.
1. Replace damaged screws.
2. Insert screws into the open thread by hand.
3. Afterwards, use a screwdriver to tighten the screws.
After decommissioning, contact with hot surfaces in the interior can lead to
burns.
Allow the L-BL2N to cool after shutting it down.
Operation with exposed or damaged parts can lead to serious injuries due to
body parts being drawn in and severed or crushed.
1. Replace damaged parts prior to beginning operation.
2. Re-attach safety and protective devices and put them back into operation
immediately after completion of work.
3. The L-BL2N should only be put into operation when fully assembled.
Changes, additions and conversions may lead to unforeseeable risks and
thus to serious injuries or death.
Modifications, additions and conversions not described in the general documenta-
tion are the sole responsibility of the operator.
Only use original parts or parts and auxiliary materials (grease, sealant) recom-
mended by the manufacturer.
Keep all notices attached to the L-BL2N in a clearly legible condition:
▪Labelling of connections
▪rotation arrows
▪Rating plate
▪Warning signs

Personal protective equipment
WARNING
Danger of crushing and cutting!
Crushing and cutting of body parts due to sharp edges or falling parts on
the open L-BL2N.
1. Wear protective gloves, safety footwear and safety goggles for all assembly
and disassembly, troubleshooting and maintenance work.
2. In addition, wear head protection for transportation and overhead work.
WARNING
Risk of injury!
Serious injuries due to body parts and hair being sucked or drawn in (vacu-
um) or due to projected particles (pressure).
1. Wear eye protection and tight clothes for all work when in operation.
2. Wear a hair net for long hair.
3. Remove jewellery and rings.
WARNING
Hearing damage!
Hearing damage due to time spent in noisy area under adverse operating
conditions or due to noise caused by conveyed media being discharged
from the gas outlet or piping.
