A dissolved oxygen level of 5 parts per billion (ppb) or lower is needed to prevent corrosion in most medium or high pressure (>200 pounds per square inch) boilers. While oxygen concentrations of up to 43 ppb may be tolerated in low-pressure boilers, equipment life is extended at little or no cost by limiting the oxygen concentration to 5 ppb. Dissolved carbon dioxide is essentially completely removed by the de-aerator.

Please understand that the main function of a de-aerator is to remove “Dissolved” gases not free air or free oxygen. The most important gases are oxygen & CO2.

requires excessive power, stuffing box or seal leakages which are very common, bearings life, overheating etc.

All these problems are critical if the pump is in process fluid service which is either corrosive or hazardous. Therefore a step by step approach is necessary to attend to these problems. Recnetly I came across a compiled list of such 50 tips which I am sharing here for you. Note down these tips & follow them whenever you get any pump problem for troubleshooting.
