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

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

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 access port enable ease of cleaning and service.

Multiple variants available

The LRP VSD+ series of liquid ring vacuum pumps is available in total recovery (standard and stainless steel), once-through (centrifugal pump and proportional valve), shell & tube and weather resistance variants.

Smart monitoring and remote controllability

The LRP VSD+ has a comprehensive in-built vacuum management system. Atlas Copco’s HEX@GRID central controller allows you to monitor, control and optimize the performance of multiple LRP VSD+ vacuum pumps simultaneously. The pump is also equipped with Atlas Copco’s MkV Elektronikon® controller as standard.

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.

The LRP VSD+ intelligent liquid ring vacuum offers superior vacuum performance 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. Elektronikon® is a user-friendly monitoring system that can integrate to your plant management system for full pump and vacuum process control and provides feedback on pump operating status, operating history, set point control and inlet conditions. 

Fully compatible with the Atlas Copco GENIUS platform, the LRP VSD+ can be connected and remotely monitored by customers almost anywhere. Atlas Copco’s HEX@GRID central controller allows you to monitor, control and optimize the performance of multiple LRP VSD+ vacuum pumps simultaneously.

Total Recovery (Standard)

A closed loop system that can also be of benefit when the seal fluid is in short supply or when contamination may be a problem.
 

Total Recovery (Stainless Steel)

Suitable for applications involving chemicals or more corrosive agents and is ideal for deal for harsher applications.
 

Once-through with Proportional Valve

Proportional valve allows the service liquid supply to be perfectly matched to the process with minimum service liquid consumption.
 

Once-through with Centrifugal Pump

Centrifugal pump with VSD control brings reliable supply of sealing water flow under required service liquid pressure without extra pressure from external piping system.
 

Shell & Tube

More resilient against contamination and allowing the vacuum system to operate in more challenging conditions such as poor water quality
 

Weather Resistant

Intended for use in outdoor and semi-outdoor installations, the weather resistant variant offers higher pump protection against moisture and rainwater.
