Speck VU / VH Series Industrial Base Mounted Liquid Ring Vacuum Pumps

                          

The Speck VU and VH Series product is ideal for industrial process applications requiring high capacity, deep vacuum, or wherever special motors such as chemical duty, washdown duty or explosion proof are required. The VU is a high capacity single stage model, and the VH is a two stage model offering deeper inlet vacuum levels.

These pumps are often sold in a complete vacuum system, including check valve, seperator tank, anti-cavitation valves, and a number of other components. Ideal for once-through water sealed, and closed-loop oil sealed systems, contact Ober-Read for assistance with your pump application. 

VU Series Pumps are rated to maximum inlet vacuum of 25.5" Hg (4.5" Hg absolute or 113 torr).
VH Series Pumps are rated to maximum inlet vacuum of 29" Hg (1" Hg absolute or 25 torr).
