The AutoPump AP4 Ultra Xtreme combines exclusive technologies to create a self-cleaning design which keeps your pumps in the well longer. Non-stick surfaces and internal agitation inhibit sludge buildup, extending service intervals and keeping clean-up to a minimum.

QED has created the first self-cleaning landfill liquid extraction pump designed to operate in the most extreme landfill conditions. The new AP4 Ultra Xtreme pump utilizes the unique, non-stick coating and polished metal internal components of the AP4 Ultra and Ultra High Temperature pumps with the exclusive AutoPump Xtreme auger. The auger creates a spinning motion in the liquid to help keep particles suspended and moving.
The combination of AP4 Ultra coating and continuous internal scouring means a reduction of over 50% of the time spent cleaning the pump’s internal components.
The new Xtreme is available as the standard AutoPump Ultra model or Ultra High-Temperature (for temperatures up to 250 °F / 120 °C).


  • Increase landfill gas extraction rates
  • Reduced risk of liquid leakage through liners and side slope failures
  • Lower rates of odors and non-methane organic compounds
  • Field tests have shown that the AutoPump AP4 & AP4.5 Ultra will last up to 10 times longer between service events. Tested in the most severe applications
  • Cleaning takes 50% less time, as determined by field tests
  • Simple disassembly with no fasteners and no cotter pins
  • AutoPumps require no surface timer-based controllers, bubblers, or sensors in the well to operate
