<p>A leaf-type filter system in which a suction pump is employed to pump filtered fluid from a series of individual filter leaves is connected to the individual leaf chambers via fluid couplings located above the surface of fluid being filtered. The couplings are of inverted U-shape and have a sliding sealing fit with the vertical outlet tube of a leaf and a vertical receiving tube mounted in a manifold or header external of the main filter tank.</p> |
