OPW Retail Fueling Introduces Pre-Plumbed DSE Dispenser Sump

DOWNERS GROVE, Ill., Jan. 16, 2024 /PRNewswire/ – OPW Retail Fueling, part of Dover (NYSE: DOV) and a global leader in fluid-handling solutions, today announced the availability of the newest member of its E-Series Fiberglass Containment Sump family, the Pre-Plumbed DSE Dispenser Sump. The new sump features all of the premium quality, fast delivery lead times and extraordinary value of the original DSE model but is now enhanced with factory-tested and assembled components.

“While utilizing the built-in quality of the original DSE Dispenser Sump, this pre-plumbed model has been designed for use by fuel-site operators looking to save time, reduce installation variability and reduce installation costs,” said Ed Kammerer, Director of Marketing and Global Product Strategy for OPW Retail Fueling. “Outfitted with factory-assembled and tested components, the Pre-Plumbed DSE builds on the standard-setting tradition of the OPW E-Series portfolio by offering superior design, materials and affordability.”

The factory-tested and assembled parts that set the Pre-Plumbed DSE sump apart include:

  • Pre-installed stabilizer bars;
  • 10 Plus Emergency Shut-Off Valves with SmartGuard™ design that helps contain shear-groove leaks;
  • Standard DSE Fiberglass Dispenser Sump base with consistent and smooth walls that help prevent leaks and other maintenance issues;
  • Available for use with OPW DPC swedge-on coupling or OPW SBC bolt-on coupling;
  • Dual-sided Rigid (REF) or Hybrid (HEF) Entry Fittings;
  • Flex connectors or NPT rigid-riser pipe nipples with pre-installed tees and elbows;
  • FlexWorks secondary test kits and test jumpers for testing the interstitial space in double-wall pipe and couplings; and
  • The fiberglass sump and all components are UL/ULc listed as a factory assembled product.

These pre-plumbed sumps can be ordered and configured for a specific site or piping layout. The one part number makes it easy to order and results in fewer loose parts to keep track of on a job site.
