Drive means are provided for driving the plunger by its foot portion, the drive means comprise a cam ring (40) arranged to be rotatable about an axis (A), the cam ring having an inner cam surface (42). The pumping unit (18) is positioned so as to be surrounded by the cam ring (40) with the plunger foot portion (32) arranged to follow said inner cam surface (42) of said cam ring (40) in such a way that the rotation of the cam ring causes the plunger to reciprocate in the bore (22).",
