Has anyone actually used magnetically-coupled liquid pumps on the liquid line (after the receiver king valve) to increase the liquid line pressure ? This is supposed to ensure 100% liquid at the TXV inlet. There is also a liquid injection line (after this pump) to the compressor discharge line to desuperheat the discharge gas.

The intention is to increase refrigeration capacity ( for an inefficient system) and reduce compressor runtime ( energy saving)

Anyone with any experience in this?
