The submersible pumps are capable of yielding up to 110 LPM each and are used solely for groundwater recovery. A remote telemetry system is utilized to monitor system performance and any alarm conditions that may occur. If an alarm condition occurs, personnel are notified of the occurrence by the telemetry system. Furthermore, the system may be re-started from the project office by means of telemetry. The LRVP creates vacuum by an impeller placed eccentrically within the pump housing.
Tap water is utilized to provide a continual supply of cool seal water into the pump housing.
The seal water is also necessary to dissipate the heat generated during the pumps compression cycle. Seal water is continually re-circulated through a heat exchanger consisting of copper tubing routed through the baffles in the air stripper, then to the suction port of the LRVP and finally back to the SKP where initiated. A temperature switch activates a solenoid valve to introduce tap water if the heat exchanger fails to cool the water sufficiently. As a protective measure, tap water is also introduced by a float switch if too much water is lost to evaporation. A ground probe remains below the intake of the pump to complete the circuit.
