The new High Clearance AutoPump AP4.5 Ultra delivers superior performance, running many times longer between service events. A pump installed for field testing needed just 30 minutes to clean after 220,000 minutes (348,965 cycles) of uninterrupted run time – in a well that had been out of compliance for the previous 3 years, requiring pump cleaning every 3 to 5 days.

AP4.5 builds upon the established AutoPump system, which has been the industry leader for over 30 years. Low-maintenance, the high-performance pump runs for months in wells where traditional pumps fail in days.

  • 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
