Pool circulation pump efficiency

18 Sep 2015

How long does it take your circulation pumps to complete one turnover of the pool water?

 

This information is normally available from the company that originally installed the pool.  If not, it’s easily calculated by dividing the volume of the pool by the maximum capacity of the pool circulation pumps.  However, this will only give the time taken if the circulation pumps are in the same condition as the day they came out of the factory.

 

It goes without saying that they’re probably not still in that same condition.  Corrosion on the pump impeller can have a significant effect on the performance of the pump and this, along with other age-related inefficiencies in the system, can increase the time it takes to complete one turnover of the pool water.

 

Bear this in mind when thinking about how long you may have to shut the pool for in the event of a biological contamination.
