DOUBLE-ACTING SUBTERRANEAN PUMP

摘要

The invention relates to a double-acting pump system for use in moving a fluid. The pump system includes a means for inputting power at a location remote from the double-acting pump. The system allows for manual power input, such as through a local pumping unit. The double-acting pump may define an interior volume and include a first end chamber in fluid communication with the local pumping unit, a second end chamber in fluid communication with the local pumping unit, a central chamber having a separating section, and a driving element (e.g., a double-ended piston) slidably located within the interior volume of the double- acting pump. The separating section may include an inlet valve section (e.g., two inlet valves) and an outlet valve section (e.g., two outlet valves).
