Quick question regarding the axial thrust a vertical turbine pump creates on the motor or driver of the pump. Does this thrust also act upon the base or foundation? Looking forward to your answers!
When using a vertical pump, the axial thrust does apply force on the base, it applies force more during the start-up, less when at constant set speed. Thrust-type bearings are used to support the axial loads created – so – yes if the base wasn't bolted, welded, or somehow fixed to a foundation it would spin hence showing there is force on the base as well. If someone posts no, then unbolt it and turn it on... just kidding, I don't really recommend that. I've actually witnessed a large one being positioned by turning it on at a very small rpm to get the base housing to move, thus aligning it for perm mounting. Not rec to do but only thing we could do. Good thing you didn't ask me for calcs on this because then I'd say, I need tons more info from you.
