Last year about this time a clever person here in the U.S. working for an owner took a pump that was overloaded and with a wave of the magic stress wand made it all better....

He did so by letting the pump slide, and then making the pump weightless, its sliding points frictionless and its inherent resistance to rotation due to its polar moment of inetria non-existent....

So these miracle workers must all go to the same university somewhere in the world (perhaps the North Pole?) Maybe the EJ is weightless????
