The Trident Pneumatic Piston Pump Model DT-01 is powered by compressed air. The control motor is located at surface grade for easy installation and maintenance. Industrial-quality air pressure is used to power the pump motor. Power to the pump is direct from grade through the sucker rod assembly. The pump removes water and product (e.g., oil, solvents, leachate) from a two-inch (4.85 cm) or greater diameter well casing to depths of 1,070 feet (326 meters). The fluid inlet is located at the bottom of the pump intake cylinder and removes water or product to 0 submergence depth.
