DOLPHIN LB – The Perfect Choice for Many Industrial Processes

Dolphin LB is a series of robust and reliable two-stage liquid ring vacuum pumps from Busch in a base plate design. Their proven operating principle enables them to be used in many industrial sectors.

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 LB liquid ring vacuum pumps may be operated as a simple continuous flow system, or as a partial or total recirculation system.

The precisely dimensioned range of sizes, extensive range of accessories and choice of construction materials, including cast iron (EN-GJL-200), 316 grade stainless steel, and higher alloy steels, such as super duplex stainless steel, hastelloy grades or even titanium, allow these vacuum pumps to be perfectly adapted to many different industrial processes. Due to their modular design and a wide variety of shaft sealing options various assemblies are possible to suit many applications.

Dolphin LB technology uses the proven liquid ring principle, with contact-free internal components and virtually isothermal compression.

The LB series has been developed for continuous operation. Even demanding applications, such as the discharge of particleladen gases or highly saturated vapours, can easily be carried out. Dolphin LB liquid ring vacuum pumps are also available in different ATEX versions.
