Edwards range of liquid ring pumps continue to provide the optimum solutions for many rough vacuum applications in the chemical and process industries. Built to last, the general reliability and low maintenance of these pumps offer the best solution when it comes to pumping wet gases or particulates. We have taken this proven liquid ring technology one-step further. By adding intelligence and an injecting innovation, we have now developed a new range of liquid ring pumps- ELRi series. 

The ELRi is a single-stage, total recovery liquid ring vacuum pump available in pumping capacities - 750, 950 and 1050 m3 /h. Based on proven Hick Hargreaves technology, the ELRi series is a compact powerhouse with improved performance. The ELRi is available in two variants – Standard variant with Plates-type heat exchanger and the Heavy-Duty variant with a Tube and Shell heat exchanger for the more corrosive and dirty applications.

Features & Benefits

• Stainless steel impellers and end plates supplied as standard
• Integrated non-return valve protects against backflow
• VSD motor with set point control to maintain and match vacuum levels
• VSD for the water circulation pump to optimise water flow and maintain stable vacuum
• Internal injection channels and mechanical seals for a stable sealing arrangement
• Lantern flange arrangement for ease of service
• Prevents the ELRi from operating in areas of cavitation
