Disc pump device for drilling pump

The utility model relates to the technical field of disc pump devices for drilling pumps, and discloses a disc pump device for a drilling pump. The disc pump device comprises a fixed flange and a connecting column body, wherein the connecting column body corresponding to the center of the fixed flange is fixedly mounted at the upper end of the fixed flange; two orthogonal radial through holes are formed in the connecting column body; and the connecting column body is hexagonal. The disc pump device is reasonable and compact in structure, convenient to use, low in labor intensity, and high in practicability; crow bars are alternately inserted into the radial through holes for rotation, so that force application is facilitated; and a pipe wrench can be occluded with the surface of the hexagonal connecting column body for pull-press rotation.
