Atlas Copco Launches Intelligent, Durable And Efficient Range Of Liquid Ring Vacuum Pumps With Dual VSD Technology

Atlas Copco Compressors LLC launches its new LRP 700-1000 VSD+ range, featuring three vacuum pumps developed for wet, humid and dirty applications. A huge departure from classic liquid ring pumps, the LRP 700-1000 VSD+ is a compact, high performance, energy-efficient system enclosed in a rugged noise-attenuating canopy.

Ensuring efficiency, the dual VSD system operates in absolute harmony within the pump. 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. Optimizing water flow within the pump element provides maximum performance and stability at all vacuum levels and operating speeds. The patented features and unique algorithms balance the operation of the water pump with the speed of the main motor.

The intelligent aspect of the pump comes through Atlas Copco’s MkV Elektronikon controller as standard, providing a comprehensive built-in management system. Key information on performance and maintenance is readily available and very visual. Multiple pumps can be monitored, controlled and optimized simultaneously, giving customers the most suitable product performance at all times. The pump can also be remotely monitored via Atlas Copco’s SMARTLINK program.

No corner is cut when it comes to the build quality; this includes stainless steel components and set-point controls. The nature of applications where liquid ring pumps should excel means that the product has been designed for the harshest processes. The Atlas Copco LRP VSD+ series is designed for an array of tough applications, including filtration, food processing, conveying, ePS, drying, degassing and plastics calibration and rubber vulcanization, to name a few. The cubicle meets IP54 standards for repelling dirt and dust.

“When it comes to pump technology, we believe in taking what has been the standard for years and driving it to the next level,” said Gerry Bergeron, product marketing manager for liquid ring pumps in the United States. “People that have looked at liquid ring pumps in the past and moved on to other solutions should take a look at this new innovation.”

With the application being at or close to the point of use, noise and size are two essential considerations. The compact, integrated design, which includes many features usually only seen on the outside of the cubicle is still up to 70 percent smaller than comparable models – this also makes it a truly plug and play design. An operating noise level in the range of 65dB(a) makes the LRP VSD+ an extremely quiet vacuum pump.

The service needs of the customer also played a large part in the design. Importantly, service can be performed while the pump is horizontal. No oil means no regular filter exchange and all areas needed for service are easily accessible. The vessel can be easily cleaned via the dedicated access port.

The LRP VSD+ range has met the strictest quality requirements, has been classified by TÜV as completely oil-free and has achieved the industry leading Class 0 status – ensuring there is zero chance of any contamination from oil.
