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.

25.5" Hg (4.5" Hg absolute or 113 torr).
