Chilled water hydraulic system design

Greetings,

I start by presenting my self, I'm a junior engineer and i work in a company where we design air cooled chillers.

I have this 7 Tons chiller, that i'll use a different system than the usual.
Usually when we work with client we go for a system with 2 closed loops, with two pump.
1st one is where the chiller work with the water tank and cool down the water contained in the tank,
2nd one between the process that needs cooling and the water tank.

This time the client wants only one pump and the water flow of needed in the evaporator is different than the water flow needed in the process machine.

I want to know the applicable configurations in this type of installation.

I am available for more details, and you can contact me with this email : benneceur.akram@gmail.com

Thank in advance and have a wonderful day everyone.
