ABSTRACT:
A high volume long distance pumping system for heavy sludges and contaminated flowables utilizes a blower powered air conveyance arrangement to draw solids and air from an available source and deliver the mixture through a hose to a separator from which extracted liquids and solids enter a closed tank hopper while air from the separator is filtered and exhausted through the blower to atmosphere. The liquid/solids mixture in the closed tank hopper is delivered by a piston pump in communication with the tank hopper through a discharge line to a point of consumption or storage.
