Hermetic liquid refrigerant pumps: A solution for eliminating leakage paths paths
A trend in the industrial refrigeration industry is advancing the elimination of leakage paths. For example, the use of welded pipe construction instead of flanged or threaded joints safeguards against refrigerant leakage.
Liquid overfeed systems are known for providing effective heat transfer and reducing operating expenses. In a liquid overfeed system with a mechanical pump recirculating the refrigerant, the use of hermetic pumps is a growing practice.
