“Large Mouth” LM Series Dispenser Sump

The Large Mouth series dispenser sump modular design provides versatility and ease of installation. There are six polyethylene bases in three lengths and two depths. These bases have a large 22” wide by 24”, 36” or 48” long openings, easing the installation of entry boots and piping connections. The ribbed riser can be cut down in 3” increments in the field to achieve proper pipe slopes with respect to grade. A variety of large mouth tops (LMTs) are available to match nearly every dispenser model. The lids are corrosion-resistant painted steel to which shear valves and dispenser frames are mounted.

Design Highlights/Advantages

  • 22” wide by 24”, 36” or 48” long opening on base gives plenty of room for boot, fitting and monitor installation.
  • Available in medium and deep burial depths to properly maintain slope. The base widens to a spacious 26” where entry boots and pipe connections are made.
  • Height modifications are accomplished by trimming of the base at the ribs.
  • Stabilizer bar kits (SBKs) mount into welded strut channels for shear valve mounting. One SBK is required for each shear valve and is purchased separately.
  • The large mouth dispenser sump is UL and ULC listed.
