Smart distinctive design

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 – a truly plug and play liquid ring vacuum pump.

Twin Variable Speed Drives

LRP 700-1000 VSD+ has not one VSD, but two. The first for vacuum set point control to maintain and match required vacuum levels and the seconds to regulate the water circulation pump. You benefit from optimized water flow and stable vacuum levels.

Anti- Seizure Prevention algorithm

The Automatic Seizure Prevention algorithm prevents the LRP VSD+ vacuum pump from seizure after a prolonged period of inactivity resulting in maximized lifetime and less maintenance.

Energy efficient and robust

The most energy efficient solution for applications with a high vapor load. No worrying about whether the pump will run out of water or when - the total recovery mode of operation improves performance, maximizes energy savings and reduces water costs.

Smart monitoring and remote controllability

Monitor and control multiple LRP VSDvacuum pumps simultaneously with Atlas Copco’s ES controllers. In addition, the Atlas Copco MkV Elektronikon® controller supplied as standard with the LRP VSDseries provides you information on pump operating status, set point control and any information for the management of the pump.


Ease of service

The time required to service the LRP VSD+ is the absolute minimum. 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.

The next big step in Liquid Ring technology

The LRP VSD+ is a truly unique liquid ring vacuum pump, offering best in class performance and connectivity. The state-of-the-art vacuum technology housed in the IP54 rated wet/dry canopy provides optimum energy efficiency along with low operational and maintenance costs. With one of the smallest footprints for a pump in its class, the LRP VSDis delivered in a single neat enclosure. The breakthrough design makes the most of the space under the canopy by optimizing accessories that would otherwise require additional space, piping and installation. The LRP VSD+ is based on the proven Hick Hargreaves design. The stainless steel impeller, endplates, liquid reservoir and heat exchanger makes this pump highly resilient against corrosion and harsh process gases. The LRP 700-1000 VSD+ is ideally suited for tough, wet and humid applications with liquid and solid carry over.
