Dismanlting Joing and Flexible Coupling in Pump Installation?

[TomosSmith]

Hi,

I'm looking at a number of pumping systems and am wondering what people's opinions are on the requirements for dismantling joints and flexible couplings/rubber bellows.

Generally if there are rubber bellows on both the pump suction and discharge, is it also necessary to have dismantling joints, or will the rubber bellows provide enough flexibility for future removal of components in the suction and discharge piping?

Any advice would be apreciated,
Thanks,
Tom
