TR-27301 2-inch Well Seal Assembly for SRX Pumps | DGSI Slope Indicator Submersible Pumps

DGSI well seals provide an easy method for connecting fluid and air lines to simplify installations.

  • Strain relief seals isolate the individual DGSI tubing sizes used on the SRX pumps and are vacuum rated.
  • The well seals are attached to the casing, 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 monitoring.
  • Eyehook included for attaching pump support cable.

Well Seals Construction

  • Fernco-type seal: Neoprene rubber, stainless steel hose clamps
  • Eyelet for pump construction: Type 304 stainless steel
  • Compression seals for hoses and tubing: Nylon® and neoprene rubber
  • Pipe plugs: Nylon®
  • Hardware misc.: 18-8 stainless steel
  • Top seal plate: Gray PVC

SRX Pumps

  • The SRX is an air-powered pump used to extract ground water or total fluids at variable rates equal to the well recharge rates.
  • The SRX is available in a 1.75in OD or 3.5in OD for use in 2” and 4” wells.
  • Pump flow rates are up to 9.5 gpm.
  • The SRX pump is available in top loading for recovering total fluids or bottom loading for dissolved phase and higher pumping rates.
  • Top-loading pumps (SRX-R TL) are selected for pumping total fluids (LNAPL and ground water simultaneously). Water table drawdown will be maintained at a level corresponding to the top inlet of the pump. Pumps of shorter lengths are available for lower drawdown requirements
  • Bottom-loading pumps (SRX-R BL) are selected for dissolved phase or DNAPL applications. When installing the pump, the head is positioned at a depth of approximately 10 inches higher than the desired water table depression.
