Dolphin pumps are the robust and proven liquid ring vacuum pumps from Busch. They are available as single or two-stage pumps with a directly flange-mounted motor, or assembled on a base plate. Their proven operating principle allows them to be used in all industrial sectors. Even critical applications such as the evacuation of saturated gases and vapours are easily managed by Dolphin liquid ring vacuum pumps.
Dolphin liquid ring vacuum pumps impress with their robust design. Thanks to the modular design of the base plate versions, custom systems can be produced easily to match specific processes.
Dolphin liquid ring vacuum pumps are designed for continuous operation. Several sizes and versions are available, and the wide range of accessories and different workshop options allow vacuum pumps to be adapted to any process. Dolphin LX liquid ring vacuum pumps are also available in ATEX versions. Dolphin liquid ring technology can also be used for overpressure generation: Busch supplies Dolphin liquid ring compressors for overpressures of up to 2 bar (g).
