A linear drive, in particular for a piston pump, includes a first electromagnetic drive device, a second electromagnetic drive device, and a drive piston configured to be moved in an axial direction by the drive devices. The first drive device and the second drive device are each in the form of a reluctance drive device. The reluctance drive devices each have a stator with a stator coil that engages around the drive piston in a circumferential direction. The reluctance drive devices each also have a coil core with a coil receptacle, open in a radial direction toward the drive piston, for the coil winding. A piston pump arrangement includes the linear drive.
