ABSTRACT:
A mechanical strainer having a stack of alternate discs and blades biased together, the discs being slowly driven by a motor and the blades being anchored on the strainer frame, which discs and blades are perforated so that water surrounding the strainer can leak into the perforations of the stack. A passage is formed in the frame communicating with the perforations of the stack, and a tube leading to where the water is desired is coupled to the frame passage. The result is a kind of labyrinth rotary seal having intended leakage.
