LRP 700-1000 VSD+ from Atlas Copco Compressors

Water and wastewater treatment is rough on hardware. The pumps used in these facilities are often constantly in use; and wet, humid conditions can quickly lower the life span of equipment not designed to handle those conditions. Fortunately the LRP 700-1000 VSD+ range of vacuum pumps from Atlas Copco Compressors was developed specifically for wet, humid and dirty applications. A 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 variable-speed drive system operates in 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. Unique algorithms help balance the operation of the water pump with the speed of the main motor.

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

The intelligent aspect of the pump comes through the MkV Elektronikon controller, providing a comprehensive built-in management system. Key information on performance and maintenance is readily available and 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.

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% smaller than comparable models — this also makes it a true plug-and-play design. An operating noise level in the range of 65 dBA makes it an extremely quiet vacuum pump. 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.
