Claim 18:
19. 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 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 such that the pump hangs down from the drive housing by:
moving the pump into the opening of the drive housing such that the pump rod extends within the drive housing;
sliding the head laterally into the drive cavity so that the head is held by the driving link and the neck extends downward through within the driving link; and
rotating the threaded ring around the cylinder to tighten the threaded ring to the bottom of the drive housing while the head remains in the drive cavity; and

removing the pump from the drive housing by:
rotating the threaded ring around the cylinder to loosen the pump from the drive housing while the head remains in the drive cavity;
sliding the head laterally out of the drive cavity; and

withdrawing the pump rod from the drive housing.
