TR-27101 SRX LP Landfill Seal Plug - 6-inch plug with Methane Extraction | DGSI Slope Indicator Submersible Pumps

Seal plug for SRX LP Landfill Pumps

SRX LP Pump Well Seals

  • DGSI manufactures a comprehensive line of well head seals for landfill leachate and gas condensate wells.
  • These well seals provide an easy method for connecting fluid and air lines, simplifying installation.
  • Standard well seals are available for wells with liquid only or gas and liquid removal.
  • Strain relief seals isolate the individual DGSI tubing sizes used on the SRX LP pumps. 
  • The well seals are attached to the casing by mating flanges or by sealing them to the diameter of the well casing with a Fernco™-type flexible coupling.
  • Additional threaded openings through the seals are provided for fluid level, pressure and/or temperature measurement.
  • Both fluid and air supply lines attach via quick-connect fittings and feature isolation valves that allow for easy pump servicing.
  • Well seal accessories include an air-in/fluid-out kit, manifold flanges, pump exhaust diversion kit and pump flow control kit.
  • Each well seal assembly includes hose clamps for attaching bundled Nylon tubing to an SRX LP pump and cable clips for securing the stainless steel cable that supports the pump. Pulse counters not included with well seals.

SRX LP Leachate Pumps

  • The SRX LP is a proven landfill pump based on a simple, innovative design and built with field-tested components. The result: a reliable pump to meet the harsh landfill environment.
  • The SRX is an air-powered pump used to extract leachate or gas condensate at variable rates equal to the well recharge.
  • Pump flow rates are up to 9.5 gpm and temperatures up to 250°F.
  • In wells under vacuum with the pump exhaust vented outside the well seal, the SRX pump can maintain the normal draw-down level when the air-exhaust line is equipped with the optional “E”-valve (part # TR-697) located below the well seal.
