Choosing the proper tank for your pumping system will greatly reduce the risk of premature pump failure. When it comes to pressure tanks, bigger is almost always better.
Larger tank = larger drawdown (actual amount of water stored)larger drawdown means longer run time and therefore less cycles, extending the life of the motor. Most manufacturers recommend a minimum run time of one minute for efficient motor cooling. One HP and larger pumps require longer run times.
To determine the proper size of tank, there are three factors to consider:
1. Pump flow rate in gallons per minute
2. Desired run time of the pump
3. Cut-in and cut-out psi of the pressure switch
From these factors you can determine drawdown needed with the following equation:
Pump flow rate X run time = tank drawdown capacity required.
Tank drawdown capacity is the minimum amount of water stored and/or delivered by the pressure tank between pump shut-off and pump re-start. This should not be confused with “tank volume.” For example, a pre-charged tank with a tank volume of 20 gallons has only five
to seven gallons drawdown capacity depending on the cut-in / cut-out (on/off) setting of the pressure switch. Pumps with flow rates (capacities) up to 10 GPM should have a tank with a minimum of one gallon drawdown capacity for each GPM
delivered by the pump.
Example: 10 GPM pump = 10 gallon “drawdown”.
Pump flow rates from 11 to 20 GPM should have tank drawdowns approximately 1.5 times the GPM rating.
For example, 20 GPM X 1.5 = 30 gallon “drawdown”.
Pump flow rates above 20 GPM should have tank drawdowns approximately two times the GPM rating and multiple tanks should be considered.
