Pipe size
(OP)
Pump suction size : 4"
Suction Pipe Line Size : 10"
So, 3 Piece of reducer may use in pipe connection as pipe/nozzle sizes have large difference.
In case of using this 3 step reducer necessarily, What problems will be caused in a pump equipment and pipe line system ?

RE: Pipe size
As an alternative suggestion - depending on the product and the flow rates, I would investigate - say a 10" blanking plate with either a 6x4 or 8x4 concentric reducer direct to the 10" blanking plate.

Also, if you are working with a viscous liquid, beware of any additional pressure drop that Artisi's proposal might introduce. Although I have used this arrangement myself (but not on a pump suction) I don't believe it is covered by the standard pipe codes. Check before you use it on a high pressure or dangerous duty. (Note that I am a process engineer and not a piper.)

RE: Pipe size
If you are pumping water, a 10"-to 4" blanking plate may trap air at the connection and cause cavitation problems with time.
You can purchase eccentric reducers that won't be such a big problem with air.

Only if you put the 4" connection at other than at the top of the 10" pipe, simply have the top of the 4" and the 10" pipe at the same level.

I wouldn't expect that the square entry of the 4" pipe onto a blanking plate to be any worse than a combination of an 10x8 + an 8x6 + a 6x4 reducer as suggested in the original posting.

They were of both the homemade and forged type.
