Pressure Tank Sizing

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.

Pressure tank sizing.

Cut in and cut out psi pounds per square inch of the pressure switch. Pressure and tank size have a direct correlation as one increases so does the other. A 10 gpm pump needed a pressure tank that holds 10 or 20 gallons. Available in diaphragm full acceptance and partial acceptance bladder designs all well x trol well tanks are made in the usa at our iso 9001 2008.

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. The more a pump must run the more wear and tear occurs to the pumping mechanism and the electric motor.

Sizing a water pressure tank properly keeps the amount of run time to the water pump held to a minimum. You will want to choose a tank with the lowest volume capacity that is greater than or equal to the total required volume. Properly sizing a water pressure tank ensures that the run time on the water pump is kept at a minimum. See example below with this information in hand you can refer to the flexcon sizing charts below to select the proper tank for your application.
