There's a p-curve of the swifty pump on this page:

[rant]
What I find curious about the review are these 2 statements
"Approximately 10-12 inches of head "
&
"MCP300™ = 59- 60 gph "

He must be figuring total head is the heigth from the pump to the highest point in the system. If you look at the p-curve, to get that flowrate there must be closer to 80" of head on that system. This is exactly why I am curious to see how much head a given item adds to a system. Your average user might look at that p-curve and figure his case is less than 30" tall so he might expect to get 250gph+ from the pump

There's also a dubious detail about that p-curve. At the bottom it states "(submersed condition - 5/8" ID output)" So in reality that p-curve is for a different pump because 5/8"ID output is impossible with the 1/2" fittings that are on the pump, and once you add tubing or adaptors 3/8" ID is the best you are gonna get

Now I'm not particularly dogging this reviewer or this company, I'm just using them as examples to point out some of the widespread misinformation thats out there. It's pretty rampant and the more I learn the more it's starting to bother me.
