PUMP SELECTION PROCEDURE
A. Determine pump capacity:
Gravity Distribution
1. Minimum suggested is 20 gpm
2. Maximum suggested is 45 gpm Perforation Discharges in GPM
Pressure Distibution Head Perforation diameter
feet inches
3.a. Select number of perforated laterals 7/32 1/4
b. Select perforation spacing= feet. l.oa 0.56 0.74
c. Subtract 2 ft. from the rock layer length. 1.5 0.69 0.90
Rock layer length
-2 ft. = feet. 2.ob o.so i.oa
d. Determine the number of spaces between perforations. a Use i.o foot singie homes.
Length perf.spacing= ft.= ft.= spaces b Use 2.o feet for anyching else.
e. spaces+1 = perforations/lateral
f. Multiply perforations per lateral by number of laterals to
get total number of perforations. a e�a 5 x ��S�ne�= perforations.

B.Determine head requirements:
1. Elevation difference between p p and point of discharge.

2. If pumping to a pressure distribution system,five feet for pressure s��°'ea°"�,�Sys«,

3. Friction loss
a. Enter friciion loss table with gpm and pipe diameter. I„ie .� Flevatinn Diffetence
Read friction loss in feet per 100 feet from table(F-14). P'�
F.L._�,��' ft./100 ft of pipe
................. . .
b. Determine total pipe length from pump to discharge ---"---""""-"""""'-"----"""""-'"'"
point. Estimate by adding 25 percent to pipe length for fitting
loss,or use a fitting loss chart(F-15 feet).
Equivalent pipe length- 125 times pi e length=
3c7 x 1.25=�feet Friction Loss in Plastic Pipe
c. Calculate total friction loss by multiplying
friction loss in ft/100 ft y equivale�pipe length� Nominal
Total friction loss= �: 3 x ��_=100= � feet pipe dia.
Flow Rate
4. Total head required is the sum of elevation difference, �m 1.5" 2" 3"
special head requirements,and total friction loss.

2. Calculate Gallons Per lnch
Thcre are 7.5 gallons per cubic foot of volumc,thcrcforc you must multiply the arca
