I have a new submersible pump installed in a newly bored well for a new house. However I am considering installing a variable speed booster pump like;
Lowara 2HM5 Water cooled Hydrovar pump and controller
With an 8 liter pressure kit
11/4 inlet feed with a 11/4 non-return valve
1 inch lever valve on outlet.
2.2 bar on a constant pressure.
Deliver 60 liters per minute at this pressure.
in-line after the buffer tank for the submersible pump before I get all my plumbing connections completed.
My question is will this cause problems? Is it likely that the booster pump could run dry because it is calling for water faster than the submersible can supply or will this depend on some mathemathics in calculating the time it would take for the buffer tank to run dry if the booster pump is running at full speed?
If so would the following avoid this problem;
Put a float switch in the buffer tank which shuts down the booster pump for a given period of time to allow it to refill. I realise this sort of defeats the purpose of the pump in the first place but I was thinking I could try this and monitor it to see if it is actually required. If it is required then I could look at increasing the size of the buffer tank. As I am an electrician the controls I am talking about would be cheap and relativly simple where as increasing the size of the buffer tank is a problem with regards to space.
