SUMMARY
The discussion centers on the operation of a 12V 30 psi pump, specifically its current draw of 2.2 amps at 30 psi. Users clarify that the 1.4 amps observed indicates a lower back-pressure than the specified 30 psi, which affects the pump's performance. To achieve the rated current draw, the pump must encounter the specified back-pressure, which requires proper outlet conditions. Additionally, there is curiosity about the pump's mechanism, whether it utilizes a spinning impeller or a reciprocating piston.
