AutoPump® AP4 Ultra for Landfill and Remediation Pumping | Overview



ultra pump insideAutoPump® AP4 Ultra


Field tests have shown that the new AutoPump® AP4 Ultra (U.S. Patent Number 9,587,483) from QED will last up to 10 times longer between service events. Tested in the most severe applications, this new pump ran longer and was easier to clean than the control group.


Low-maintenance pump lasts up to
10 times longer between service events and requires 50% less time to clean


Several improvements contribute to this longevity. The AP4 Ultra uses proprietary non-stick finishes on the float and discharge tube to reduce solids buildup, extending the time between cleaning and making it much faster and easier to clean the pump. All metallic parts are 316-grade Stainless Steel, which has greater corrosion resistance and can withstand the attacks of the harshest leachate. The AP4 Ultra’s redesigned air control mechanism uses no fasteners or cotter pins for easier disassembly and greater reliability.

“Cleaning has been an easy task, most times just requiring a water spray,” said one user. From another, “We removed residue with some clean water and a swipe of the hand.”

The new AP4 Ultra builds upon the established AutoPump® system, which has been the industry leader for over 30 years, and includes QED's unmatched customer service.
