I will tell you what my understanding is about Skip's pumps compared to others. Someone probably knows more and may contribute.
The design of Skip's impeller is what is known as a mixed-flow design that can move more volume with less pressure than the other pumps that are centrifugal design that create more pressure to push through restrictions. It's a bit of an anomaly in my opinion for some to taught Skip's pumps as high volume when they are only such if you remove the thermostats which, if you do, makes any pump high volume. Since it is so important to have thermostats keeping the engine above minimum operating temperature both in hot and cold weather it doesn't make any sense to me to sacrifice the benefit of thermostats just to get more flow from a pump that is no higher volume with thermostats than any other pump.
Hope that makes sense. Much more discussion on the difference between Skip's pumps and others here:
