According to The Law Of Proximity, the "it" in your example
The Pump gives 10 bar pressure to the Machine and it will give good production.
Meaning, the machine when it receives 10 bar of pressure is capable of good production.
"It" is closest to machine, otherwise the author might have written
The Machine receives 10 bar pressure from the Pump, and it will give good production.
unless some other context is given
The Pump gives 10 bar pressure to the Machine and it will give good production to other machines that need pressure.
Also, since the production of the pump is already mentioned, it can be assumed by context that the pump has good (sufficient) production.
