Abstract
A pump is driven by rotation of an electrical motor drive shaft. An eccentric drive unit includes an eccentric member coupled between the motor drive shaft and the pump drive shaft. The eccentric member has an offset portion parallel to and offset from the motor axis for orbiting around the motor axis. A flexible boot encloses the offset portion. A pump end static seal seals a pump end of the boot at an interface between the eccentric member and the pump drive shaft. A motor end static seal seals a motor end of the boot at a motor end of the eccentric member.
