can i use an external pump for the chiller?
if so then i would need to connect the pump before the chiller right or can i connect it after the chiller?

Yes you can.
Always connect pumps BEFORE equipment. You want no resistance whatsoever in the flow of water from the source to the pump chamber, you don't want the pump to have to "pull" water through anything. Rather, you want to use the pressure of the pump to push water through equipment.
So if you have a sump, you want to come out of the sump (through a drilled hole preferably) into the pump, then from there to the chiller, then back.

Ditto.
Will just add, keep in mind the flow rate of your chiller.
If the pump puts out too much, you need to valve down.
If valving down reduces the flow to the tank too much, you may need to divert water two ways (one to chiller and back to tank and the other directly to tank).
Alternative would be to do a dedicated pump for the chiller, valved down to what you need for flow rate.
