For selecting WELL-X-TROLs for a different running time than ESP I or ESP II, and/or at pressure ranges the same or different than 20/40,30/50, 40/60:
THINGS YOU MUST KNOW
1, System flow rate (pump capacity or discharge) GPM

. Min. . Psig. Psig . ESPVol. |
|
2. Desired running time, in minutes and fractions of minutes (1.5 min. = 1 min. 30 sec ) 3. Pump cut-in. in gauge pressure 4. Rump cut-out, in gauge pressure CALCULATING TANK SIZE 5. Multiply Line 1 by Line2 and enter ESP Volume |
