Abstract
A vertical in-line split couple pump includes a motor shaft having a motor shaft collar; a pump shaft having a pump shaft collar with a pump shaft angled collar surface oblique to an axis of the motor and pump shafts; and a coupler having coupler halves that attach together, that have a couple groove to receive the motor shaft collar, and have a couple angled groove to receive the pump shaft collar. The couple angled groove has a couple angled groove surface oblique to the axis. The coupler halves respond to a force that moves them together to couple the pump and motor shaft together, moves the pump shaft angled collar surface in relation to the couple angled groove surface, causing the pump shaft to move upwardly towards the motor shaft along the axis, to provide a way to jack-up and recouple the pump shaft and any impeller attached thereto by one mechanic.
