Compact liquid ring vacuum pumps have a modular design

Dolphin LM/LT liquid ring vacuum pumps feature integrated flow channels and FKM or FFKM mechanical shaft seals. Engineered for once-through circulation systems in open or closed liquid cycles, the pumps offer the vapor and particle tolerance to make them suitable for the removal or extraction of wet gases or vapors. Available with pumping speeds from 58 to 510 ACFM, they come in different ATEX-compliant versions and temperature classes for operation in potentially explosive environments. The Dolphin LM models are single-stage vacuum pumps for a rough vacuum range from atmospheric pressure to 100 Torr ultimate pressure, while the Dolphin LT units are available in two-stage versions and cover a vacuum range from atmospheric pressure to 25 Torr.
