Abstract

The invention relates to a metering pump (1) comprising a base part (2), a drive shaft (11) that can be rotated relative to the base part (2), a pivoting part (9) that can be pivoted relative to the base part (2), a cylinder (3) with a cylinder axis (Z), said cylinder lying on the pivoting part (9), and at least one piston (10) which is movably mounted in the cylinder (3) and which is connected to the drive shaft (11) in an articulated manner. The pivoting part (9) can be moved relative to the base part (2) such that the orientation of the cylinder (3) relative to the base part (2) and/or the position of the cylinder (3) relative to the base part (2), in particular the angle (α) between the cylinder axis (Z) and the drive shaft (11), can be adjusted. According to the invention, the cylinder (3) is removably connected to or can be connected to the pivoting part (9), and/or the pivoting part (9) is removably connected to or can be connected to the base part (2).
