delevan pump and percarb?

[rj242 16]

Anybody use their Delevan pump to spray a sodium percarbonate cleaner on decks? If so, do the bubbles cause pump problems? I had a Pwer tell me that the bubbles cause his Shurflow to lose prime sometimes.

Just replaced a Shurflo with a Delevan on a unit, but am sure we will run into the same situation with sodium percarbonate.

When first mixed with hot water, sodium percarbonate off gases a ton of oxygen. This is what initially "chokes" the pump and is the cause of "bubbles" in the line.

If servicing a small job, we will just use a backpack pump up to apply. Otherwise, start with the backpack, and allow the mix to cool and off gas excess oxygen, then start using the Delevan. 10 to 15 minutes is usually sufficient.
