I am in the market for a new pump - and I will buy an eco - variable speed pump (Viron P320) here is Australia. I discovered on the net - that when this pump is running at low speed - gas bubbles form in the salt cell.
The issue identified from another site:
I have had a VX9T chlorinator for around 12 months (no problems) and I have just installed a Viron EVO P320 pump. I am having a problem with the VX9 cell housing trapping gas bubbles when the pump runs at low speed. The bubbles soon form a larger bubble, which eventually exposes the cell plates. This could lead to a melted cell housing or possibly an explosion. The problem also occurs at minimum speed, but to a lesser extent (only on higher chlorinator settings). I'm currently thinking the EVO pump was a complete waste of money.
The recommendation from the manufacturers - is to run the pump at higher speeds until the bubbles are gone - but for me - this defies the reason for buying a slow speed pump - if i have to run it at higher speeds - it is less efficient...or should i look for another chlorinator that doesn't have this issue? Can you guys run your pumps at low speed without this issue?
Can variable speed pumps run at the lowest speed without causing gas bubbles?
(I initially thought you could turn the cell upside down - but i am told that the "gas trap" is needed to prevent gas building up in the filter. When it builds up in the cell casing - a safety mechanism turns it off....whereas if it build up in the filter - there is no safety mechanism.).
