I’m going to show you how easy it is to size a pressure tank! • Sizing Chart Link: https://www.rcworst.com/Shared/conten... • 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. • Sizing Chart Link: https://www.rcworst.com/Shared/conten... • • If you need more information or assistance with products, call 855.329.4519 or email [email protected] to speak with an industry expert.
