Pressure tanks amtrol pre pressurized potable water well tanks are engineered to reduce surge and ensure minimum pump run time in municipal well systems and high pressure booster pump applications.
As the tank fills with water it compresses the air chamber.
In general there is no problem with using a larger pressure.
The pump turns on when the system reaches the low pressure cut in and off when the high pressure cut in.
Because the pressure tank is a core component of the entire well system responsible for regulating pressure and for easing the workload of the well pump the importance of selecting a the right well pressure tank cannot be overemphasized.
You will want to choose a tank with the lowest volume capacity that is greater than or equal to the total required volume.
An under sized pressure tank can cause a water pump to run an excessively.
How does a well pressure tank work.
The more a pump must run the more wear and tear occurs to the pumping mechanism and the electric motor.
The goal in sizing a tank is to make sure the air side is large enough so that when the desired amount of water is put in the tank the air is not compressed to a pressure greater than system design.
The normal pressure spread for cut in and cut out is 20 30 p s i.
The figure that is calculated on line 7 is the total tank volume required based on the given design criteria.
