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.
- Intrinsically safe design and approved for hazardous environments
- Fits 4" or larger diameter wells
- Ability to pump from 250' below ground
- Can pump particles up to ⅛" diameter
- Consistently pumps fluids as light as 0.70 SpG reliably
- New adjustment-free valve mechanism – no magnets
- Improved float design for maximum buoyancy and chemical compatibility
- Optimal working pressures as low as 1 psi above head pressure
- Standard light-weight composite housing, corrosive resistant 316 stainless steel and PVDF parts for less maintenance
- Fast and simple disassembly for easy maintenance

| *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. |
