Hydrogen Peroxide Pump Treatment after Stopping the Operation

Proper treatment on hydrogen peroxide pump is very important in order to maintain its performance and pump lifetime. Hydrogen peroxide left in pump and piping may decompose releasing gas (oxygen) and heat, and then develop pressure inside the pump and piping. Uncontrolled pressure causes the pump damage and leakage through pump seals and gaskets in piping.

To prevent such problem, you have to remove remaining hydrogen peroxide from the pump and then wash the pump with demineralized water for at least five minutes just after stopping the pump. Finally, make sure to close suction valve of the pump and open slightly the discharge valve. Proper treatment on hydrogen peroxide pump after stopping will also ensure successful pump start up.
