Intelligent Liquid Ring Vacuum Pumps

The LRP VSD+ intelligent liquid ring vacuum offers superior vacuum delivery and connectivity. It provides optimum energy efficiency along with low operational and maintenance costs. Its ease of use, integration into existing processes and centralization capabilities make this a truly unique liquid ring vacuum pump. With a small footprint, the LRP VSD+ is delivered in a single neat enclosure. The noise containing canopy significantly reduces noise pollution in the immediate working environment with an operating noise level in the range of 65 dB(a). Equipped with Atlas Copco’s MkV Elektronikon® controller as standard, the LRP VSD+ has a comprehensive in-built vacuum management system.

Twin variable speed drives
The first VSD for vacuum set point control to maintain and match required vacuum levels. The second VSD regulates the water circulation pump, offering you optimized water flow and stable vacuum levels.

Multiple variants available
The LRP VSD⁺ series of liquid ring vacuum pumps are available in total recovery (standard and stainless steel), once-through (centrifugal pump and proportional valve), total recovery system with shell & tube heat exchanger variants.

Plug and play
Cleverly engineered in a smart design the LRP VSD⁺ series is enclosed under a strong canopy offering a sleek and ergonomic look with the HMI, inlet, outlet and main cable connections located on top of the canopy.

Anti – seizure prevention algorithm
A safe operation that prevents the LRP VSD⁺ vacuum pump from seizure after a prolonged period of inactivity resulting in maximized lifetime and less maintenance.

Ease of service
IP54 rated cubicle, horizontal serviceability, mechanical seals, lantern flange arrangement with automatic alignment of the motor, the removable heat exchanger and the convenient multiple access port enable ease of cleaning and service.

Cavitation prevention
Standard total recovery configuration results in lower water consumption meaning reduced cost of ownership.
