FIELD: cleaning engineering.
SUBSTANCE: device comprises coating made of a set plates that abut one against the other. The plates are rectangular or square in the plane. Each plate has the central through passage arranged along one of the longitudinal axes of the plate parallel to its outer surface and side passages. The slot that connects the side passage with the outer side of the plate is made along the length of each of the side passages. The central through passages of all plates are oriented in a single direction, and coaxial central through passages of any two adjacent plates are interconnected to form a common passage that is connected with the pipeline connected with the device for pumping out fluid.
EFFECT: enhanced reliability.
