Concentrated acid pump sump water seal

2019-02-11View Original

Thread Content

The water seal in the pump tank for dry-suction concentrated acid must be filled with water before shutdown, to prevent the leakage of SO2 and acid mist as well as the entry of outside air. But should the water seal water be kept or drained after driving? Why keep it or why release it? Some sulfuric acid plants release the water seal water after starting up, while others keep the water seal water in place.
