• C E E Condensate Pumping Controllerless AutoPumpO System AP-4/131L LEACHATE I S P E C I F I C A T 1 O N S The AP-4/BL Leachate System is an automatic Leachate Extraction and Condensate Pumping recovery system that recovers fluids from depths up to 300 feet and flow rates over 14 GPM. Able to function in 4-inch wells and larger, this controllerless system works without the use of any external controls, bleeders, or bubblers. The AP-4/BL Leachate Extraction and Condensate Pumping System consists of an AutoPump (an automatic, controllerless, air- displacement pump), filter/pressure regulator, hose and hardware package, and well cap. METHOD OF OPERATION The AutoPump (Model AP-4/BL) is initially placed in a recovery well(s) and its bottom inlet submerged below static leachate or condensate conditions. Given a regulated supply source of compressed air, the pump is cyclically emptied in response to being filled through the bottom inlet. As the pump fills, an internal float rises until it comes in contact with an upper stop that is connected to a mechanical lever assembly which simultaneously opens an air supply poppet valve and closes an air exhaust poppet valve. As a result, air pressure builds up within the pump body and displaces the fluid contents up and out of the pump through a discharge ball check valve. As the discharge cycle progresses, the float falls, and prior to being completely empty, the float comes in contact with a lower stop that triggers the lever/valve assembly again; closing the air supply poppet and opening the air exhaust poppet. The pressurized air then exhausts and the pump is allowed to refill itself, thus beginning a new cycle. This cyclic operation continues automatically as the leachate or condensate level is drawn down within the well. When the AP-4/BL "catches up" with the well, the fluid level in the well is maintained roughly two thirds above the bottom inlet of the pump, and the AutoPump is pumping at a rate equal to the well yield for that specific draw down level. CONTROLLERLESS PUMP The AutoPump Model AP-4/BL is a submersible bottom-loading pump that : • Is air-displacement in type, requiring only a regulated compressed air source. • Requires an operating pressure of 5 psi above static head. • Requires no external remote control panel or satellite controllers. • Self-adjusts discharge flow rate automatically to match well yield (up to the pump's capacity). • Uses air only when discharging fluids, therefore, air usage is optimized. • Functions under positive or negative (vacuum) pressure environments. • Does not require clean, dry air to function properly and pumps particles up to 1/8 inch in diameter without problems. • Can operate on contaminated air. • The air valve can pass 90 weight gear oil without fouling.
