| AutoPump® Automatic Air-Powered Remediation and Leachate & Methane Condensate Pumps (U.S. Patent Number 5,004,405)
 QED’s patented AutoPumps originated the automatic air-powered pump concept in 1986 and has led the industry ever since. AutoPumps were designed specifically to handle difficult conditions reliably and safely, including hydrocarbon (LNAPL and dissolved phase) remediation, landfill leachate and methane condensate pumping, solvent (dissolved phase and DNAPL) cleanup, suspended solids, silts, corrosives, and high viscosities, along with high temperatures and frequent starts and stops.
Air-powered AutoPumps are proven worldwide at thousands of remediation and landfill sites, which is why AutoPumps are the No. 1 choice of professionals based on reliability, durability, performance range and technical support.
The superiority of the AutoPump design is based on four key strengths:
• high clearance fluid pathways
• using air as the motive force
• materials of construction matched to site conditions
• a simple yet rugged operating mechanism
Unlike electric pumps, air-powered AutoPumps use no high-speed motors, bearings or impellers, so AutoPumps don’t heat up, sieze up or get ground up. AutoPumps do not agitate the liquid which is typical of electric pumps. Air-powered also means eliminating the dangers and costs of electricity at and in the well.
Finally, AutoPumps actually have a built-in control system - they pump when there is liquid present and shut down when the level is drawn down, without the need for any sensors in the well or controls at the surface.

AutoPumps Advantages
▼ Tubing and Hose Sets: Special jacketed nylon tubing sets, another QED first, provide the ultimate in chemical resistance, light weight, easy handling and small downwell profile. Hose bundles use high grade materials and provide flexibility advantages in many installations.
▼ Discharge Check-Valve: High flow, wear resistance, easy, complete disassembly and optional materials are additional examples of AutoPump design leadership.
▼ Discharge Head: All AutoPumps use Stainless Steel discharge heads for long term wear and durability.
▼ Casing: Fiberglass casing are lightweight and dent-proof; Stainless Steel options are available for special site conditions.
▼ Fittings: Special AutoPump barbs provide massive pull-out strength with tubing and hose, and many quick-connect options are offered to ease installation and service.
▼ Air Control Mechanism: AutoPumps use the most proven air control machanisms available to provide reliable cycling over many years, resisting solids buildup, chemical attack and wear.
▼ Float: Special float materials and metal end plates are designed to resist chemical attack, buoyancy changes and wear, to provide the power to drive the air control mechanism reliably.
▼ Intake Valve: Rugged, high-clearance inlet check valves provide high flow yet resist wear due to pumping abrasive solids. Careful material selection ensures durability.
