SPECK VHC Liquid Ring Vacuum Pumps

SPECK VHC two-stage liquid ring vacuum pumps:

The SPECK VHC series liquid ring vacuum pumps are two-stage base-mounted pumps specifically developed for industrial applications requiring high vacuum, excellent operational stability, and high resistance to wet gases, vapors, and process fluids.

‍

Thanks to their innovative modular design, they can compress almost all gases and vapors, whether dry, wet, or saturated.

The operating principle is based on the proven liquid ringtechnology, which simultaneously ensures sealing, cooling, and compression of the intake gas.

The VHC range benefits from the latest technological developments from SPECK:

Two-stage vacuum pump for achieving high vacuum levels.
Continuous operation for intensive industrial applications.
Modular design allowing for custom configurations.
Oil-free technology in the compression chamber.
Pre-set cavitation protection for safe commissioning.
