If a pump is operated by using compressed air at 7 barg does this mean the discharge line of the pump is at 7 barg whilst liquid is being pumped?

ab12cd, I take it this is an AODD pump? If so, the answer is no! The discharge press can be anywhere from grater that 0 barg to 7 barg at the dead head condition.

Don't mix up pressures with work. Work (ie, energy) depends also on the motive quantities and volumes, and the moved pressures and flow rates, and of course, efficiencies.
