Dolphin LM Vacuum Pumps


Busch Dolphin LM

Busch Dolphin LM is the new generation of liquid ring vacuum pumps from Busch, with all the advantages of proven technology plus additional refinements.
Dolphin LMs are single-stage vacuum pumps for rough vacuum applications from atmospheric pressure to 130 hPa (mbar) ultimate pressure. The Busch Dolphin LM series is available in a total of five sizes, allowing an exact match to every process.
The operating fluid is usually water, but other liquids may be used if required by the process conditions. Busch Dolphin LM 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 allow these vacuum pumps to be perfectly adapted to many different industrial processes.
Busch Dolphin LM technology uses the proven liquid ring principle, with contact-free internal components and virtually isothermal compression.
The LM series has been developed for continuous operation to support a wide range of processes in many industrial sectors, including the chemical and pharmaceutical industries.
