I can answer, but know that what I say I learned here. So, be warned. LOL
High pressure pumps are rated to be able to pump a certain amount of water at a certain height. Like from a basement to a roof for example. 0' @ 3000 gph, 30' @ 2500 gph. Hope I am right and that it helps. Michael |

Circulation pump has those ratings too. For example: Gen X Pump
Model GPH Max Head Fittings Watts PCX-30 825 14.5 ft 3/4" MPT 100 PCX-40 1190 22 ft 3/4" MPT 110 PCX-100 1550 29 ft 1" MPT 360 PCX-150 2131 40 ft 1" MPT 480 PCX-55 1140 26.2 1" MPT 170 PCX-70 1537 31.8 1" MPT 180 So what's the difference? |

laud's right. A high pressure pump is designed to pump the water to a higher head[heighth] and keep it's flow, i.e., a return from a basement and such and a low pressure/high flow is for a low to moderate head , i.e., closed loop.

Just figure out what head pressure vs. how much flow you'll need. If your sump is in your tank stand and you'll only have about 6-8 feet of head pressure and won't need a high head pump, those are for going from the basement up to your tank or something and use more electricity. Here's link to a head pressure calc that will help you decide:

Its just a rating. Pressure rated pumps have the ability to deliver flow with high back pressure. All The Gen-X pumps you listed are suitable as "high pressure" pumps.
