One daft question regarding the difference between fire pump UL/FM approved and general pump in the same capacities apart from its price. Technical aspects only !
Test method? material components specified ? or even some prohibits according to the related code, NFPA ?

If we have the model of fire pump and its controller, how can we make sure that these models are UL listed/ FM approved?
Is there any source on the internet to prove it?
Thanks in advance for your kind advice.
