Deep Well Application (Single Pipe System)
Where pumping water level is greater than 25 feet and inside
diameter of well is 2, 2-1/2 or 3 inches. On single pipe deep well
installations, clean, sound well casing must be used to give a tight seal.
NOTE: This application requires a well adapter for the top of the well.
NOTE: Pre-soak packer leathers for approximately two hours before
installation.
1. Attach foot valve directly to bottom of ejector assembly. Ejector
must be submerged 10 to 15 feet below pumping water level and
the foot valve must be at least five (5) feet from bottom of well.
2. Attach foot valve and packer ejector to suction pipe (presoak
packer leathers for approximately two (2) hours). Push the
assembly down the well. Some force may be required to push the
ejector down the casing.
3. As each section is lowered, check for leaks by pouring water into
the suction pipe.
4. Attach well adapter to suction pipe, lower over casing top and
tighten adapter flange.
5. If no leaks are found, proceed to WELL TO PUMP CONNECTION
(SUCTION PIPE) using piping of the same diameter as the suction
pipe (1-1/4”) and pressure pipe (1”) tappings of the pump. For long
offset distances, see chart on page 9 for the proper pipe size.
6. Unions in suction and discharge piping near pump and well will aid in servicing. Be sure to leave enough surrounding room so that wrenches
can be used easily.
