It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)
RE: Pump type selection
Hypochlorite will offgas, which is the formation of gas in the piping system caused by heat, sunlight, low pumping rates, idle time, or a combination of these. System and pumps are often designed with venting at the discharge and highest point in the system to prevent vapor lock. Maintain a flooded suction condition if possible. Suction lines should be 2-3 times larger than the pump inlet.
