This manual describes the function and operation of the 4” Auto-Reclaimer (AR4). It provides detailed information about the system including the system components, installation, operation, maintenance, and troubleshooting.
The Geotech AR4 is an automatic, controller-less, positive air-displacement pump designed for recovering fluids from depths of up to 250 feet (76.2 meters). It operates using a regulated standard industrial compressed air source and is available in three lengths: short, long, and extended (Ext). The pump can handle fluids with up to 1/8" diameter suspended particles and operates under both positive and negative pressure environments. It is offered with various intake configurations, including top screen, bottom screen, or flat bottom screens.
The document provides detailed instructions for system installation, including attaching air, vent, and discharge hoses, and lowering the pump into the well. It details system specifications such as physical dimensions, weight, maximum depth, air pressure requirements (10-120 PSI), and fluid compatibility. The manual also includes sections on replacement parts, a maintenance schedule, and troubleshooting guides for common issues.
