Ground water remediation/vapor extraction

Soil vapor extraction systems often utilize a Graham oil sealed liquid ring vacuum pump for the vacuum source when low soil transmissivity conditions exist in the contaminated area. This condition requires a much greater vacuum to achieve acceptable vapor removal.

Oil sealed liquid ring pumps have many advantages in these applications. Due to the low vapor pressure of oil, a much greater vacuum can be achieved than with positive displacement blowers or even water sealed vacuum pumps. This allows extraction from wells greater than 30 feet deep. The oil sealed vacuum pump is used in a closed loop system and does not require water for sealing or cooling. This eliminates the need for treatment of contaminated water.

The Graham oil sealed liquid ring vacuum pump package consists of a Graham liquid ring pump, a vapor/liquid discharge separator, an oil mist coalescing filter, an air cooled heat exchanger, all associated piping, and necessary accessories for remote operation. Instruments provided can be explosion-proof rated. We can even supply the oil for the system.

Graham Corporation has a complete line of standard oil sealed liquid ring pump packages pre-engineered for your soil vapor extraction and groundwater remediation application or we can engineer a package to meet your particular specifications.
