What if water gets into our engine?
(OP)
Hi dear friends, I hope you can help me in this situation.
My company has a fire pump where his driver is a diesel engine, the problem is that the rain water gets into our engine for the muffler. We don´t start the engine because we don't know what consecuences could happen.

Really bad things could happen if enough water gets into the engine. It can cause something called "hydrolock" or "hydraulic lock". It's worse if it happens on the intake side, but it can be bad enough on the exhaust side.
Presumably you are looking for options. There are plenty.
Orient the exhaust outlet downward and below the level of the exhaust manifold.
If the exhaust outlet has to go up through the ceiling, put a rain cap on top of it. Or, have the pipe go straight up for whatever appropriate distance, then install a 180 degree bend and have the outlet face down.
Design an intentional low spot in the exhaust system between the engine and the exhaust outlet, and put a tiny drain hole at the bottom of that low spot. Yes, a tiny bit of exhaust will leak out when the engine is running.

It won't do any good as a broken machine.

As for your exhaust system installation, most major manufacturers have specific installation guidelines for engines, there are plenty of acceptable solutions to deal with preventing water entry.
Depending on where you are, you may have air pollution regulations to deal with, in some areas I work all diesel engine exhaust stacks must discharge vertically, even standby generators and fire pumps.
Hope that helps, MikeL.

I can't imagine such a cover would be all that expensive, plus it would prevent expensive damage to such a degree that its cost could be considered trivial.

CAT actually sells raincaps now, I guess the steel coffee can going extinct provided a new business opportunity!
I did go to a site in Hawaii last year that tried to use a 5 gallon plastic bucket, worked great until the engine started, funny, instead of blowing off it jumped around on the top of the exhaust pipe until it got hot then melted, then what was left made a nice smokey stinky fire. The local fire captain was less than pleased, especially since the owner had in hand a proposal for a nice new shiny stainless steel raincap, I guess the callout for the fire department was more than the $250 for the raincap.
Ah, for the old days!
