I have a piping contractor that is placing a pair of victaulic couplings between the anchor for the piping system and the main pump. I have concerns that large pipe loads will be transfered to the pump flange leading to a collection of problems such as early bearing failure due to shaft couplings forced out of alignment to possible pump flange failure due to fatigue. This is a 3500hp slurry pump operating in series to produce a gage pressure of 350PSI in the 30 inch pipe that is in question. If the victaulic couplings are not at their limit in linear movement, can someone give me a simple calculation to determine the loads transferred to the pump discharge flange?
