High Pressure Pump?

[Bcollins111900]

I have tried asking this question in another forum here in RC a while back and got no response. What makes a high pressure pump high pressure? What makes it any differend than another pump? Reason I am asking is I am picking up a new skimmer that needs a high pressure pump.... just not sure what make a pump "high pressure"?

9 times out of 10 if you look at the chart and it had a tall head but lower GPH, it's pressure.

For example, look at two similar pumps by Panworld:
PX-50 - 590gph and 16.5'
PXX-50 1110gph and 13'

Typically the pressure pumps will have smaller inputs and outputs, where flow will have large ones. In short the pressure pumps are built to get a smaller GPH way up in the air. Flow based move massive quantities of water, but after X amount of feet of head they just stop working at all or become incredibly inefficient.


Tell us what you're getting and we can likely supply you with some ideas.

so a blue line HD 100 which is 1900 GPH with a 45 ft head is high pressure?

Any of the blueline or panworld pumps that are over 29ft head are high pressure as far as I know.

I think I am going to go this route instead Iwaki MD40RLT 750GPH @4ft, 21.3 head. Correct me if I am wrong but this is a pressure rated pump as well?

Was just looking at something else and stumbled on this. Unless you have a SUPER deal on the MD40 already, I'd grab this:

$80 shipped for the iwaki. I also picked up the panworld you posted Eric. Good looking out!
