Ok, I finally have all my parts for my loop:

HARDWARE

Koolance RP-401X2 Single 5.25 Reservoir for 1-2 PMP-400 Pumps
*XSPC / Laing DDC-1T Plus Ultra 3.2 (18W) - MOTOR
EK Supremacy MX (CPU Waterblock)
EK-Thermosphere – Nickel (GPU Waterblock)
EK-RAM Monarch x2 Nickel (RAM Waterblock)
EK-RAM Monarch black plates
2 x Magicool G2 Slim Radiator 16 FPI - 240mm
6 x EK-Vardar F1-120 (1150rpm) Radiator fans

FITTINGS & EXTRAS

12 x EK-ACF Fitting 13/19mm – White
4 x EK-AF Angled 90° G1/4 Nickel
Arctic MX4 Thermal Paste
2 x Mayhem Pastel Ice White 1Lt
3 x Twin 3mm UB White LED

There's no going back on any of these parts (i have them all here, bought and paid for).

My Koolance rez allows me to have two pumps. I have purchased only one. Should I buy another pump, or will the one pump work fine?

Nah you will be fine.

I currently have three radiators, and loads of bends and my flow is fine on a D5 pump on setting 3.

However, I am doing a complete new loop design soon, along with new everything. :D
 
I ran 2 x 240 once and then a 480 + 240, with a single DDC-1T+ with out any issues(Single GPU & CPU block).
Only thing with a DDC is that is does have a tendency to make a slight noise and/or vibration if not de-coupled properly.

You would be fine with just 1, if you have 2 it would be good for redundancy, but there are other(cheaper) ways to handle that. Also running dual DDCs would give you too much head pressure and flow rate you might want to reduce it(Yes there are ways to reduce flow rate of a DDC)
 
I have 2 D5s in serial for my new build in progress.

The primary reasons for this are aesthetics and redundancy. Also because I have double the pumps, I can run both at half the speed I would normally cutting down on noise and wear and tear on the pumps.
 
I have two d5 running as I bought them in kit form, I tested with 1 and it'll pump ok but it's nice having the knowledge if one fails I can still use the PC waiting for a replacement to turn up.
