Prevent backflow and protect your system
We recommend installing a non-return valve on your liquid ring vacuum truck to prevent backflow and protect your system. If the pump is stopped with vacuum in the slurry tank, a strong backflow can cause water from the pump to be sucked into the slurry tank, leading to increased water loss. The non-return valve must be placed on the discharge side of the pump and must fit the internal piping system. For example, our Non-Return Valve CI DN100 is suitable for a 4-5” piping system, which is commonly installed on vacuum trucks operating with a 4 or 5” suction hose. The Non-Return Valve CI DN100 can be delivered as a stand alone component or integrated with the Truck Master 4 or 5 solution. New to liquid ring technology?
