Abstract
A pumping device includes a frame body, a pump body, a piston rod, a drive shaft, a main guiding member, a carrier block, a plug unit, and a rotary-to-linear motion conversion mechanism disposed between the carrier block and the drive shaft so as to convert rotation of the drive shaft to linear motion of the carrier block. A shaft axis of the drive shaft and a piston axis of the piston rod cooperatively define a vertical plane. A bottom surface of the carrier block is guided by the main guiding member and defines a bottom plane which is orthogonal to the vertical plane.
