-2- Utilizing the Maximum Capacity of Full Acceptance Well-X-Trol ® s Series 400, 420, 440 and 450 When used with conventional pressure ranges, these Well-X-Trol models use only a fraction of their maximum capacity. For Example: A WX-423 with a total volume of (275) gallons will accept the following...

-3- For example, if we look at a typical pump curve for a (15) HP – (85) GPM submersible pump – we can select a pump cut-in and cut-out point on the curve which will provide optimum pump operation.The pump curve shows pump performance as its pressure rises from cut-off ( ( 0 ) head in test) to maxim...

Subtracting the feet of head required for lift (240 ′ ) we can convert this point to PSIG: Maximum pump cut-out = 420 feet Less lift = 240 feet Maximum pressure = 180 feet To convert feet of head to PSIG, we divide by (2.31) (there is (2.31) feet of head for each PSI): 180 ÷ 2.31 = 77.9 or 78 PSIG.O...
