Abstract
A magnetic coupling system may be used in a fluid displacement apparatus to magnetically couple a drive shaft to a piston. The magnetic coupling system may include first and second magnetic couplers at the ends of the drive shaft and piston, respectively. The first magnetic coupler and second magnetic coupler may be configured to exert an attractive force. A bearing between the magnetic couplers reduces friction and side loading.
