Procedure to add a flood coolant to 7i96s

I have recently converted my mini lathe with a 7i96s. Everything is working amazingly well. 
I mostly turn plastics, brass and aluminum. While drilling plastics, namely acrylic- I need to go to a depth of 65 mm which melts the acrylic if I fail to provide coolant properly. 
I would like to add a flood coolant system to my lathe. Maybe just adding a DC motor pump to the 7i96s would serve the purpose. I have learnt that I can add an external SSR to the 7i96s outputs and driving the DC pump through the external SSR. But I am a bit unsure about the wiring (total newbie in electronics, also my fear of blowing up my 7i96s), can anyone help me with the wiring and maybe if I need something more for the electronics setup?
​

As per your request, attached is a diagram depicting 7i96s driving a DC pump motor using an external SSR. The SSR specs must match your motor power.

 
 

The out pins are small SSR outputs so need a supply voltage, say

+5V --> OUT0+
OUT0- --> POWER SSR IN+
POWER SSR IN- --> 5V GND

That solves my doubt. Thanks everyone. I will see if I have any problems with the setup. 

"High current outputs 0 through 3 use full floating MOSFET switches ( a DC Solid State Relay or SSR ) and can be used just like a switch or relay contact. Maximum voltage is 36 VDC and maximum load current is 2A. Inductive loads must have a flyback diode. The output polarity of outputs 0 through 3 must be observed (reversed outputs will be stuck-on)."

I intend to use a 12v common power supply for both the output supply voltage and the DC motor. I hope that isnt a problem or should I have separate power supply for both? 

Also I think a DC motor is inductive. Do I need to use a 4001 diode to the DC motor?

If you intend to drive a small DC motor directly from the 7I96S outputs,
then yes, you need a flyback diode across the motor.
The motor also should not have more than 2A of stall current.
