DOLPHIN LG / LR – The Largest Liquid Ring Vacuum Pumps

Dolphin LG/LR is a series of robust and reliable single-stage liquid ring vacuum pumps from Busch in a base plate design. Their proven operating principle enables these high-capacity vacuum pumps to be used in many industrial sectors, including power plants, sugar production as well as pulp and paper industry. Even demanding applications, such as the discharge of particle-laden gases or highly saturated vapours, can easily be carried out.

The Dolphin series encompasses decades of experience in the manufacture and use of liquid ring vacuum pumps, offering perfect vacuum generation in challenging environments.

The operating fluid is usually water, but other liquids may be used if required by the process conditions. Dolphin LG/LR liquid ring vacuum pumps may be operated as a simple continuous flow system, or as a partial or total recirculation system with a liquid separator as standard.

The precisely dimensioned range of sizes, extensive range of accessories and choice of construction materials, including cast iron (EN-GJL-200) and 316 grade stainless steel, allow these vacuum pumps to be perfectly adapted to many different industrial processes. Due to their modular design, various assemblies are possible to suit many applications.

Dolphin LG/LR technology uses the proven liquid ring principle, with contact-free internal components and virtually isothermal compression. The LG/LR series has been developed for continuous operation.
