Geotech AR4 4" Auto-Reclaimer

Total Fluids Recovery Pump

The AR4 is designed to pump floating hydrocarbons, leachate, and condensate in total fluids applications. The AR4 is operated automatically, and needs no controller. Everything needed to operate the system is built into the pump. The design withstands the harshest and most corrosive environments such as landfills or mines.

Specific gravity and viscosities will alter specifications. Flow rates will vary with site conditions. **Activation levels shown above reflect activation levels for pumps with a bottom or top and bottom inlets. To determine the activation level for a flat bottom intake, subtract 5" (12.7 cm) from the minimum activation level measurement above.
