Spec Sheets

The octagon-shaped Closed Bottom Double Wall Tank Sump is ideally configured for piping laid out in 45- and 90-degree angles. It comes standard with a snap-lock lid with imbedded O-ring seal to make it watertight. There is a v-groove pour channel to join the two-piece containment sump eliminating the need for lamination. The pour channel allows communication between the base and the top-hat. The sump is VPH compliant and the top-hat ships under 20” HG vacuum to ensure integrity.​
