QED Environmental Systems Highlights High-Clearance AP4.5 Ultra AutoPump® System

High-performance pump runs for months in wells where traditional pumps fail in days

Dexter, MI - Q.E.D. Environmental Systems, Inc., a leading manufacturer of innovative environmental products, highlights the AP4.5 Ultra AutoPump System, a low-maintenance, high-performance pump. This pump delivers superior performance and extends run time between service events. The pump incorporates innovative technology which allows it to run for months in wells where traditional pumps fail in a matter of days. The AP4.5 Ultra AutoPump System represents a breakthrough in landfill and remediation pumping.


The AP4.5 Ultra AutoPump System design has increased clearance between the float, casing, and discharge tube. The AP4.5 Ultra AutoPump System has three times the clearance of regular pumps which enables it to deal with higher viscosities, greater concentrations of solids content and precipitates. In addition, the pump utilizes 316-grade Stainless Steel which resists corrosion even when exposed to harsh leachates and high temperatures.

The unique technology makes pump cleaning easy and ensures pumps will stay clean longer. The pump has a proprietary non-stick finish that reduces solids buildup. A field test of this model in a difficult well ran for 348,985 cycles - uninterrupted. Afterwards, it required just thirty minutes to clean. The process to clean is simple: a water spray and a light wipe will do the job.

The AP4.5 Ultra AutoPump System features a fiberglass pump body, stainless steel pump ends, internal components, and fittings for tubes and hoses. This standard model is 4.5 inches in diameter, is 39.3 inches long, weighs 17.8 pounds, and can reach a maximum flow of 13 gpm.

T.J. Davies' Retention Knobs

Our retention knobs are manufactured above international standards or to machine builder specifications. Retention knobs are manufactured utilizing AMS-6274/AISI-8620 alloy steel drawn in the United States. Threads are single-pointed on our lathes while manufacturing all other retention knob features to ensure high concentricity. Our process ensures that our threads are balanced (lead in/lead out at 180 degrees.) Each retention knob is carburized (hardened) to 58-62HRC, and case depth is .020-.030. Core hardness 40HRC. Each retention knob is coated utilizing a hot black oxide coating to military specifications. Our retention knobs are 100% covered in black oxide to prevent rust. All retention knob surfaces (not just mating surfaces) have a precision finish of 32 RMA micro or better: ISO grade 6N. Each retention knob is magnetic particle tested and tested at 2.5 times the pulling force of the drawbar. Certifications are maintained for each step in the manufacturing process for traceability.
