Running a pump

Main Question or Discussion Point

So I am try to run this 12V 30 pis pump and it says to run it at 2.2 amps @ 30 psi.

When I supply the pump with 12V I get a reading of 1.4 Amps so I don't really know what it means by the 2.2 Amps and the @ 30 psi means.

Can anyone tell me what this means?
Thanks

I think it means for a 30 psi head (back-pressure) and nominal flow rate the pump will pull 2.2 amps. If you're only seeing 1.4 amp draw it's likely because you have a back-pressure lower than 30 psi on the pump when its running.

Oh so I think you mean that I have to apply 30 psi to the outlet of the pump which will cause the pump to work harder and draw 2.2 amps.

Thanks

Do you know anything more about the pump? Does it have a spinning impeller or does it have reciprocating piston?
