1. A method of mounting and dismounting a pump from a drive housing having a bottom and an opening extending through the bottom of the drive housing, and from a driving link located within the drive housing, the driving link comprising a drive cavity located within the drive housing, the pump comprising a cylinder comprising a top end, the pump further comprising a threaded ring located on the cylinder such that the cylinder extends above the threaded ring and below the threaded ring and the threaded ring is rotatable around the cylinder, and the pump further comprising a pump rod that extends out from the top end of the cylinder, the pump rod comprising a head connected to a neck, the head wider than the neck, wherein the method comprises:
securing the pump to the drive housing by:
moving the cylinder into the opening of the drive housing such that the pump rod extends within the drive housing;
sliding the head into the drive cavity so that the head is held by the driving link and the neck extends downward within the driving link; and
engaging the bottom of the drive housing with the threaded ring which tightens the pump to the drive housing and thereby prevents the head from sliding out of the drive cavity; and

removing the pump from the drive housing by:
disengaging the threaded ring from the bottom of the drive housing which loosens the pump and thereby releases the head to slide out of the drive cavity;
sliding the head out of the drive cavity; and
withdrawing the cylinder from the drive housing.
