what is the power consumption when pumping in paralel?
do you add the individual power consumptions of each pump?

RE: pumping in parallel
If you added the second pump while modifying the piping system (with larger pipe size)to make the total friction lose same as previous for one pump, you are getting doubled flow with same efficiecy - just like as if you added a parallel system.
RE: pumping in parallel
one big pump will probably have better efficiency than two smaller pumps delivering same Q,H; but this effect is not important compared to other design issues (proces demands, reliability...and commercial offers!)
usually we consider that by increasing pump size, relative dimensions of gaps and tolerances decrease, resulting in better efficiency.
