DEF Series
Dispenser Sump

The DEF series dispenser sumps feature all the same benefits as the DCL, CLE and CLS but includes an internal partition to separate the Diesel fuel from the DEF fuel within the sump.

Dual Compartment
An internal containment compartment separates fuel products from DEF (Diesel Exhaust Fluid) while still utilizing a single powder coated steel frame.

Heavy-Gauge Steel Frames
The dispenser sump frame is manufactured from heavy gauge steel, providing strength and rigidity, and is designed to lock into the concrete foundation.

Single Conduitless Entry
Electrical Conduit can enter into the bottom of the dispenser without penetrating the sump walls, creating less risk for water intrusion.

Standard Features

Duo Molded Technology

Duo-Molded Technology

Our fiberglass sumps utilizes Duo-Molded Technology. Using premium raw materials with a high glass content, we create two layers of fiberglass, offering superior strength and fuel resistance.


Our signature ‘Brite-White’ interior reflects light for better visibility and makes identifying leak points easier.

100% Fiberglass

100% high-quality, non-corrosive fiberglass provides long-term reliable containment from fuel exposure without voiding warranty, warping, cracking or becoming brittle.

Universal stabilizer bars

Universal stabilizer bars with 3-axis adjustment accommodate multi-product dispensers without displacing product lines and ensure proper load transfer in case of an impact from any direction.

Single Piece Construction

Constructed as a single piece which eliminates any seams, providing less places for water penetration.

1″ Composite Rainlip

1″ Composite Rainlip protrudes from the bottom of the dispenser to prevent surface water from entering the sump. This also offers better protection against rust and corrosion than metallic rainlips.
