CLEAN ENVIRONMENT ENGINEERS, INC. <br /> SOS AUTO PUMP <br /> FUNCTION: <br />' This system removes water from wells at up to 10 gallons (37.5 liters) per minute. It can <br /> be used without a control box to maintain continuous pumping from a well and it will <br /> maintain a predetermined level in the well without external sensors. The Auto Pump <br />' can be used as either a Top-Loading Pump to take in floating oil and water or as a <br /> Bottom-Loading Pump to take in and remove only water. Tqe pump senses when it is <br /> full and when it is empty. It regulates the pressurized air to itself, to push the fluid out, by <br />' admitting pressurized air or to fill itself again by exhausting the pressurized air. <br /> The Auto Pump will match the fluid influx into the well up to its maximum flow rate. It can <br />' turn "on and off" millions of times without damage to itself. Thus, it is very useful in low <br /> flow rate situations where the fluid in the wells is removed quickly and the pump must <br /> then lie dormant until the water level again rises. The pump can pass silt and sand up <br /> tto 0.125" (3.2 mm) diameter. <br />' METHOD OF OPERATION: <br /> Fluid enters the cylindrical pump body through a check valve. After the fluid rises to <br /> within about 6" (15 cm) from the top of the pump, a pneumatic valve is shifted to allow <br /> pressurized air to enter. The fluid in the pump is thus pushed out of the pump through <br /> another check valve. As the fluid is pushed out of the pump by the air pressure and the <br />' level nears the bottom of the cylindrical chamber, the pneumatic valve is shifted back <br /> and the pressurized air is exhausted from the pump. The pump then fills again and the <br /> cycle repeats as long as fluid is present. <br />' The pump can be steam cleaned without damage. <br /> ' FLOW RATE: <br /> AP-4: 0-7 gallons per minute (26.5 liters per minute) <br /> AP-6 0-10 gallons per minute (37.5 liters per minute) <br /> SIZE: <br /> ' AP-4: 3.5" (8.9 cm) diameter, 50" (152 cm) in length <br /> AP-6 5.5" (14 cm) diameter, 66" (168 cm) in length <br /> ' WEIGHT: <br /> AP-4: 28 pounds (12.7 kg) <br /> AP-6: 90 pounds (40.9 kg) <br /> 1 MATERIALS OF CONSTRUCTION: <br /> Stainless Steel, Brass, Delrin, Polypropylene, Urethane, Viton and FRP <br />
