Anyone who operates and maintains underground storage tank (UST) systems for containing and dispensing petroleum products is aware of the difficulties of keeping water out of their sumps and spill buckets. These sumps and spill buckets are designed to keep liquids from leaking out to the environment; however, they are not designed to keep groundwater from coming in due to hydrostatic pressure. In fact, this problem almost always exists at sites that have high water tables or where the tank pit has been installed into the impermeable layer of a confined or semi-confined aquifer, creating a "bath tub" affect.
What many UST operators don't know is that these tank pits can be dewatered using IMT's UST Pit Dewatering System, which consists of a pump, controller, and a liquid-phase carbon vessel.
Pump
Grundfos submersible pump assembly with check valves and throttling valves equipped with constant pressure control, soft-start, and integrated dry-run protection. High efficiency 2-wire, single-phase, permanent magnet "Smart Motor", which communicates via a Grundfos CU300 status box through the power leads.
Controller
The Grundfos CU300 status box is used for constant pressure regulation and allows the installer to communicate with the "Smart" Motor through the R100 wireless infrared remote control.
Liquid-Phase Carbon Vessels
Liquid-phase carbon absorption vessel, rated for 15-gpm and 10-psi. Includes virgin granulated carbon, 2-inch inlet and outlet connections, pressure gauges for measuring the pressure differential across the carbon vessel, cam locks for easy installation and removal, and back-flush valves for flushing carbon.
