Abstract
A vertical pump driven by a motor having a construction which permits removal and replacement of the motor by remotely controlled equipment. The motor frame is secured to the pump with hold down bolts and the motor shaft is connected to the pump shaft by a unique, tapered coupling arrangement in which a motor coupling half is rigidly secured to a pump coupling half with a drawbar. The motor shaft is hollow and the drawbar extends through the hollow shaft drawing the coupling halves firmly together. The drawbar and hold down bolts are arranged to be selectively loosened or tightened by a remotely operated nut runner.
