What is the advantage of flooded suction over lift suction?
When pumping gaseous chemicals such as sodium hypochlorite (bleach) or hydrogen peroxide using a flooded suction type application will virtually eliminate the need for repriming. As the chemical off gasses the gas rise’s to the top of the tank and only liquid is fed to the pump via gravity. If your pump has a degassing valve you will want to make sure that this function is not used as the chemical would continuously exit the bleed port. Flooded suction applications are not recommended for use with degassing head type pumps.
