An induced flow reciprocating double disc pump assembly includes a rotating frame supporting a double disc pump, the rotating frame has a plurality of supports and a shaft defining a horizontal axis of rotation. A stationary frame supports the rotating frame and includes a plurality of bars and uprights and a flange bearing assembly engaged each of the shafts permitting rotation between the rotating frame and the stationary frame. A locking pin positions the rotating frame and the stationary frame at a plurality of positions relative to each other. A rotation crank is engaged to the shaft. The rotating frame has a first position relative to the stationary frame supporting the double disc pump in a vertical direction and a second position where the double disc pump is in a horizontal direction.
