There is flushing water for both the inlet and outlet. For the inlet, the plug valve should definitely be closed to allow the flushing water to flow in and be discharged in reverse direction. For the outlet, it is recommended to use a pump for flushing; only if the pump fails to start should flushing be carried out by allowing the water to flow out in reverse direction. Here, there is flushing water at the outlet as well, which can be used for cleaning
There is flushing water for both import and export; it is also possible to use a level sensor at the slurry outlet tank to activate pumping for flushing
At our inlet, there are hard pipes for flushing water; by closing the inlet valve and turning on the flushing water, it can be discharged directly from the pump outlet, or it can be routed from the pump outlet to the drum screen and then into the gutter
