[RE-wrenches] Small pump in larger casing

[Ray Walters]

I agree with Bob-O, no torque arrestor is needed.  We've hung small 
submersibles in hand dug wells 5 ft in diameter.  You can actually hang 
several pumps, as long as you keep them from knocking into each other on 
installation.  The pump does not move around like you might think,  
something is wrong if it is banging into the casing on start up.
