INNOVATION-PACKED
VARIABLE SPEED DRIVE LIQUID RING VACUUM PUMP
Atlas Copco announced what the
company described as a new
breakthrough in the world of liquid ring
vacuum technology with the launch of
its LRP 700-1000 VSD+ range of intelligent liquid
ring vacuum pumps.
Ideally suited to wet, humid and dirty applications,
the LRP VSD+ is a state-of-the-art vacuum
solution with unrivalled innovation and integration
capabilities. A huge departure from the classic
liquid ring pumps available in the market today,
the LRP VSD+ is a compact, high performance,
energy efficient system enclosed in a strong,
noise-containing canopy.
The ergonomic design of the LRP 700-1000
VSD+ along with market leading HMI ensures
the optimum operator interface and ease when
controlling the vacuum pump. In addition, inlet,
outlet and mains cable points are positioned
on the top of the pump for straightforward
installation. It is not least this feature that makes
Atlas Copco's LRP VSD+ an uncomplicated plugand
play product.
“The LRP VSD+ not only brings energy and water
savings to our customers, but also saves on
space. Its compact design and small footprint
allows users to save space without having to

sacrifice any vacuum performance,” says Alistair
Darroch, product manager.
The same applies to functionality: this pump
contains a large number of performanceoptimised
components that would normally
be supplied as accessories, often taking up
additional space for piping and installation. With
the LRP 700-1000 VSD+, these components
have been integrated into the pump element to
maximise efficiency, performance and space
saving.
The soundproof housing significantly reduces
noise pollution in the immediate working
environment. With operating noise in the range
of 65dB(a) the LRP VSD+ is an extremely quiet
liquid ring pump. Along with noise reduction, the
sturdy canopy and cubicle ensure that the pump
and internal electronics are effectively protected
against dust and water. This feature qualifies
the LRP 700-1000 VSD+ series for the harshest
industrial applications – extending the lifetime of
the electronic components as well as the service
intervals.
Speaking on the engineering design of the LRP
VSD+ series, Mr Darroch says, “The LRP VSD+
vacuum pump is a true breakthrough in liquid ring
technology as we know it today. No other liquid
ring vacuum pump offers this level of efficiency
and economy, while maintaining a high degree
of build quality and standard scope of supply.
We drew from over 150 years of engineering
know-how and applied Atlas Copco’s innovative
approach to create something truly unique. By
combining the classic and rugged benefits of
LRP with Atlas Copco’s variable speed drive
technology we are introducing something that the
market has not seen before.”
The integrated variable speed drive technology is
particularly unique. The twin VSD system operates
in absolute harmony within the pump, ensuring
optimal vacuum performance at all times. The
primary VSD accurately maintains required
vacuum levels by controlling the operating speed
of the pump, matching pump performance to
process demand and saving energy. The second
VSD regulates the water circulation pump in
response to the operating conditions seen.
Optimising water flow within the pump element
and providing maximum performance and stability
at all vacuum levels and operating speeds.
“Adding to the intelligence of the pump are
multiple innovations that allow the LRP VSD+ to
uniquely meet the needs of the customers and
the demands of modern day industrial processes
and situations.”
