The drive head assembly comprises a flange retaining mechanism for retaining the plunger flange to the drive head assembly, and a load measuring device for measuring 10 compressive force on the plunger flange, the load measuring device being movable within the drive head assembly transverse to the axis. The syringe pump comprises a self-centering mechanism having a pushing component which is arranged to move the load measuring device within the drive head assembly until the pushing component abuts against the plunger flange, such that a centre of the load measuring device is 15 aligned with the axis.1/14 C LA NC 00 LACC14 r.J
