Doublewall B-9000

B-9000 Jumbo Deep Monitored DoubleWall UDC

The B-9000-D-AB Series Deep Under Dispenser Containment sump (UDC) is the bigger brother of the DoubleWall B-8000′s big brother: 8” wider and 5” deeper. This sump allows for piping to enter from the sides and provides a ton of room for piping components, series piping runs and flex connector sweeps. It consists of a structural steel frame sealed to a deep twin-walled jumbo monitored fiberglass sump, which has a compressive resistance of over 1300 PSI and ships under a continuous vacuum test at 20”Hg+.

A factory-installed combination pressure/vacuum gauge is provided for vacuum monitoring and testing during installation. Each sump ships with slightly more monitoring fluid than is required. This sump includes our interchangeable dispenser frame and stabilizer brackets. It accommodates a variety of options including our Electrical Offset (EO = Conduitless) system, shear valves, vapor brackets and factory-installed entry fittings. You also have the option at time of order to increase or decrease the height of the UDC if required. Paired with any of our bonded all-fiberglass entry fittings, you will never have to worry about water intrusion or the risk of contaminating the local environment. There is no UDC larger or more secure than this one.
