New plug & play VSD liquid ring vacuum pump

Jon Lawson

Atlas Copco has launched the LRP 700-1000 VSD+ range of intelligent liquid ring vacuum pumps. 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 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.

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 vulcanisation, the new product is an advanced vacuum solution with excellent integration capabilities.

The variable speed drive (VSD) technology integrated into the LRP VSD+ is particularly innovative. The twin VSD system operates in 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.
The ergonomic design of the LRP 700-1000 VSD+, along with its 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 reduces noise pollution in the immediate working environment. 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.
