Atlas Copco Launches Plug & Play Variable Speed Drive Liquid Ring Vacuum Pump

29.03.2019

Atlas Copco has announced 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. 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.

With one of the smallest footprints for a pump in its class, the LRP VSD+ is delivered in a single neat enclosure. The breakthrough design makes the most of the space under the canopy by optimising accessories that would otherwise require additional space, piping and installation. The same applies to functionality: this pump contains a large number of performance-optimised components that would normally be supplied as accessories.

“The LRP VSD+ not only brings energy and water savings to our customers, but also saves on space. Its compact design and small footprint allow users to save space without having to sacrifice any vacuum performance”, explains Alistair Darroch, Product Manager, Liquid Ring Vacuum Technologies.

Ideally suited to wet, humid and dirty applications with liquid and solid carry over, including filtration, food processing, conveying, ePS, drying, degassing and plastics calibration and rubber vulcanization, the LRP VSD+ is a state-of-the-art vacuum solution with unrivalled innovation and integration capabilities.

The Variable Speed Drive technology integrated into the LRP VSD+ 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.

“Intelligence is a key feature of the LRP VSD+. Our patented features and unique algorithms balance the operation of the water pump with the speed of the main motor. This guarantees that the pump always delivers peak performance while maintaining maximum energy efficiency,” comments Darroch.

The ergonomic design of the LRP 700-1000 VSD+, along with HMI, ensures the optimum operator 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.

The soundproof housing significantly reduces noise pollution in the immediate working environment. Indeed, with operating noise in the range of 65dB(a) the LRP VSD+ is an extremely quiet liquid ring pump. Along with noise reduction, the IP54 rated wet/dry 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.
