LNAPL/DNAPL Recovery

QED has been making the industry's most diverse range of equipment for LNAPL and DNAPL for more than 20 years, using site experience to develop reliable, effective products. Unlike a single technology, this unmatched line of proven performers -- from active pumps and patented in-well separators to passive skimmers and simple pneumatic pumps -- will match your site needs precisely. Backed by customer support from QED application experts at the factory and in the field, plus our international network of trained local representatives, your project will operate successfully, with less downtime and lower O&M costs.

Skimmer Pump Systems for LNAPLs

Combining the Genie® remediation bladder pump with your choice of floating skimmer inlets, these systems have proven to be a reliable and durable design for free-phase groundwater remediation projects. They match the requirements for many sites, with a choice of programmable controller or automatic operation without surface controllers or timers. Durable bladder material and tough construction ensures reliable and trouble-free operation. High suction capability maximizes product recovery rates.

2" Genie Skimmer Pump
Automatic air-powered system collects floating hydrocarbon with minimal water from 2" recovery wells without requiring an above-well controller.

  • Available in 2 pump lengths/rates and 3 inlet float travel ranges, a total of 6 models.
  • Sized to fit wells 2" (50 mm) ID and larger.
  • Uses specific gravity inlet; most effective for gasoline and kerosene recovery (<0.85 SpG).

4" Genie Skimmer Pump
Automatic air-powered system collects floating hydrocarbon with minimal water from 4" and larger recovery wells without requiring an above-well controller.

  • Available in 2 inlet types, 2 pump lengths/rates and 3 inlet float travel ranges, a total of 12 models.
  • Sized to fit wells 4" (100 mm) ID and larger.
  • Choice of specific gravity or hydrophobic screen inlet to exclude water from recovered product.

2" Programmable Genie 
Air-powered system collects floating hydrocarbon with minimal water from 2" recovery wells; operated by a C100M controller for easy setting of pump rates and on/off cycles to match well recharge rates.

  • Available in 2 pump lengths/rates and 3 inlet float travel ranges, a total of 6 models.
  • Sized to fit wells 2" (50 mm) ID and larger.
  • Uses specific gravity inlet; most effective for gasoline and kerosene recovery (<0.85 SpG).

4" Programmable Genie Pumps
Automatic air-powered system collects floating hydrocarbon with minimal water from 4" and larger recovery wells without requiring an above-well controller.

  • Available in 2 inlet types, 2 pump lengths/rates and 3 inlet float travel ranges, a total of 12 models.
  • Sized to fit wells 4" (100 mm) ID and larger.
  • Choice of specific gravity or hydrophobic screen inlet to exclude water from recovered product.

Passive Skimmers for LNAPLs
QED offers the most complete line of floating inlet skimmers for free-phase, product only, hydrocarbon (LNAPL) extraction in 2" (50 mm) or 4" (100 mm) wells or larger. Superior performance is the result of more than two decades of continuous development and improvement.

SPG Passive Skimmers
Floating skimmer positioned by specific gravity recovers hydrocarbon without water.

  • Available in 2" (50 mm) and 4" (100 mm) ID models.
  • Built-in reservoir stores product for collection.

SOS® Passive Skimmers
Floating skimmer uses hydrophobic screen to recover hydrocarbon without water.

  • Available in 2" (50 mm) and 4" (100 mm) ID models.
  • Built-in reservoir stores product for collection.

AutoSkimmer™ LNAPL Pump
This automatic air-powered pump delivers high floating product recovery rates from wells that recharge rapidly. Cycling only when the pump body fills, it conserves drive air for energy efficiency. Combining an AutoPump with a rugged SPG floating inlet, it can be switched from skimming to total fluids pumping by simply removing the floating inlet.

AutoSkimmer™ for Automatic LNAPL Pumping

The most efficient device for high flow rate product recovery, this versatile performer responds to fluctuating well level and LNAPL layer thickness to meet changing site needs over longer time intervals.

  • Available for 4" (100 mm) ID and larger wells.
  • Built-in on/off control with internal float.
  • Recovers up to 275 GPD of LNAPLs.

DNAPL Pumps
QED supplies the industry's most complete selection of automatic and programmable pumps for DNAPL recovery. Air-powered systems are intrinsically safer than electric pumps in potentially flammable or explosive hazards.
Pulse Pump® Pneumatic Displacement Pumps
QED's original remediation pump line; proven performance for nearly 25 years.

  • Available in 2" (50 mm) and 4" (100 mm) ID models in a variety of rugged materials.
  • Simple operation with only 2 moving parts for ultimate reliability.
  • Choice of electronic or all-pneumatic controllers.

Iron Horse™ Extended-Duty Piston Pumps
Air-powered piston pumps bring the ruggedness of oilfield and concrete pumps to your site.

  • A reciprocating air cylinder at the wellhead drives a piston downwell, connected by a flexible fiberglass rod. Ideal for extreme low draw-down and high viscosities.
  • Isolates driver air from pumped liquid, eliminating air emissions.
  • Extended duty between service compared to other piston pump designs.

Eliminator™ Remediation Bladder Pump
Recovered product has no contact with pump drive air, eliminating air emissions of volatiles.

  • Available in 2" (50 mm) and 4" (100 mm) ID models.
  • Long-life PTFE bladder isolates pumped liquid from air supply.
  • Effective for skimming viscous hydrocarbons (i.e., crude oil).
