DEEP WELL TWIN PIPE

DEEP WELL TWIN PIPE
Twin Pipe Suction Piping
A twin pipe jet assembly is used in wells 4" and larger.
Our 4" jet assemblies require a minimum 1
and 1" drive water pipe; 5" jets require a minimum 1
suction and 1 1 ⁄ " drive water pipe. Use of smaller piping

will reduce performance in gpm and pressure. Offsets
over 50' require larger pipes to reduce friction loss and
to obtain published performance.

1 1 ⁄ " and 1 1 ⁄ ". Install a foot valve on the male
2 4
thread bottom port on the jet assembly or on the end of a
34' tail pipe. The tail pipe prevents over pumping a low
yield well so the pump will not break suction. See Tail
Pipe in Technical Section.
Lower the jet assembly into the well. It should be set at
least 5' below the static water level. Keep the jet a few
feet off the well bottom to lessen the possibility of
sucking debris into the jet. The connections at the well
head can be either a pitless adapter or a well seal.
Priming will be easier if you fill the pipes with water
before attaching the pump.
Connect the suction and pressure pipes to the threaded
connections on the face of the pump. This can be done
using unions and threaded pipe nipples, or barbed
connectors with poly pipe. Always double clamp barbed
connectors. Make sure that the piping slopes upward to
the pump and that no point is above the pump suction.
On long offsets it is easier to prime the system if you fill
the pipes with water before connecting the pipes to the
pump. Go to Deep Well Discharge Piping.

DEEP WELL PACKER SYSTEM

DEEP WELL PACKER SYSTEM
Packer Suction Piping
Packers use the area between the well casing

and the suction pipe as the drive water

packers only: Use the Goulds Pumps turned couplings
part #64655 to connect the sections of 1
pipe. This special diameter turned coupling increases the
clearance between the 2" well I.D. and the O.D. of the
coupling to allow the drive (pressure) water to easily pass
the couplings. Failure to use them will have a negative
impact on pump performance, both pressure and gpm
will decrease. The pump may easily lose prime while
pumping due to the restriction!

Using smaller than recommended pipe may reduce gpm

Install Packer Assembly
To ease installation soak the 2" or 3" packer assembly in
warm water to make the leathers soft and pliable. DO
NOT lubricate them with grease, oil, or petroleum jelly!
The leathers must absorb water to seal the packer
assembly against the well casing.
Check to make sure the nozzle is installed in the jet
assembly. Install the venturi tube in line with the nozzle.
Install a strainer (not supplied with packer assembly) on
the bottom port of the packer assembly or on the end of
a 34' tail pipe. The tail pipe prevents over pumping a low
yield well so the pump will not break suction. Attach the
packer assembly to the suction pipes using the Goulds
Pumps' turned couplings to connect the sections. Insert
the packer assembly into the well casing and push it
down. Attach the other pipe sections as you lower the jet
into the well. See Tail Pipe in Technical Section.
Attach Suction Pipe To Packer Adapter
Packer systems always require a Packer Adapter at the
well head. The adapter makes the transition from vertical
to horizontal for horizontal pumps, and it connects
vertical pump casings to the well casing and suction pipe.
See the list of Packer Adapters/Pump Models to see
which one your pump system requires. See Chart 1 for a
list of Packer Adapters/Pump Models.
After the jet assembly is inserted into the well, attach the
Packer Adapter to the top of the suction pipe. Screw the
top section of 1 1 ⁄ " male threaded suction pipe or a
4
threaded adapter into the 1
in the 2" packer adapter or a 1
3" packer adapter.
Make sure that the O.D. of the well casing is free of dirt
and burrs. With the gland bolts loosened the tapered seal
ring on the packer adapter should slide over the well
casing. After insuring that it is in place tighten the two
gland nuts to compress the seal ring and seal it to the
well casing O.D.
Install the pump by attaching it to the Packer Adapter
using the bolts and gaskets provided. Vertical models use
studs and nuts for ease of assembly.

DEEP WELL DISCHARGE PIPING

DEEP WELL DISCHARGE PIPING
All deep well jet pumps require back pressure

line. The valve must be located between the
pump and the first discharge port. It is best to locate it as
close to the pump as possible. Failure to install and adjust
a pressure control valve will result in loss of prime during
peak usage such as filling a washing machine, bathtub or
using outside hose bibs.
