The realistic point is ideal flow, 1.5gpm. What happens when you're closer to ideal flow, 1.5gpm? 24v D5 is 6.7psi vs 6.2psi.
Now what's the cost of configuring a D5 to run 24v? Are you going to run a top like 99% of the people who get D5's do? Either way it's a helluva lot more than one 35x (85+40+40), not just in price but cost of power consumption as well. It costs 22w to run a 35x at optimal flow versus 34w.
The kicker is that the D5 will be running full on 34w all the time unless you are actively at the control turning it down, where a 35x will be puttering along dialed down via the PWM 5-6w all automatic, hell 30% duty cycle is a bit more than I run at idle.
No, you read my post wrong. I compared both pumps at psi at ZERO flow, and gave both pumps specs in gpm at high restriction on martins curve. It was you that incorrectly mated my psi listing at ZERO flow, with the specs I gave gpm at high restriction curve.
You stated "The 35x2 will beat dual 24v D5s and will consume less wattage than 1 24v D5, a lot less". The first part of your sentence is wrong. The second part is correct.
I would not buy a D5 strong, unless my supply volts was 24v and had no means to decrease to 12V. And I would buy a mcp35x over a D5 strong for my own use, no question. But no point in stating incorrectly that mcp35x will beat a D5s when both listed specs, and independent testing by martin clearly show that to be false. There are enough valid reasons to get a mcp 35x over a D5s some of which you listed.Edited by opt33 - 8/20/12 at 3:32pm
