- SELECTING THE PUMP - The most popular pump
in America is the 11 HD, with it's sealed packing, it's
the ideal pump for drinking water.
- SELECTING THE PUMP FLANGE - The pump flange
attaches to the well. The hand pump attaches to the
pump flange. You must provide the nuts, bolts and washers
(available at your hardware store) to connect the pump to
the pump flange. Measure the inside diameter of your casing
and then select the appropriate pump flange 3" thru
6". The standard pump flange will suffice in most cases.
If you are especially concerned about contamination, order
the sealed flange. Although the pump flange is not
required to complete the system, it is highly recommended
to stabilize the hand pump and prevent any rocking motion.
- SELECTING THE CYLINDER - This is the part of the
system that goes down the well typically below the water
table. It's a barrel with a plunger inside. When you pump
on the handle of the hand pump it makes the cylinder plunger
go up and down. This forces the water up the pipe and out
the hand pump. The cylinders come in three sizes, 2",
2.5" and 3 inch. They are sized by their inside diameter.
The 2" will fit inside a 3" well, the 2.5"
will fit inside a 4" well and the 3" will fit
inside a 4" or 5" well. Keep in mind that the
11 HD pump has an adjustable stroke and can be shortened
or lengthened to make pumping easier or to pump more water
per stroke.
- SELECTING THE PUMP ROD - The pump rod, sometimes
referred to as sucker rod, provides the mechanical connection
between the hand pump and the plunger in the cylinder. This
means when you pump the handle, it makes the pump rod and
the plunger go up and down, delivering the water out the
spout of the hand pump. Pump rod is threaded and coupled
and comes in 21 foot lengths. Order enough pump rod so that
your cylinder is about 15' below water in the well. Or more
in the case of very low yield wells.
IMPORTANT: Always order one additional coupling. (besides
what comes with the pump rod) You'll need it to make the final
connection.
NOTE: You will also need 1-1/4" x 21' lengths of pipe.
This is the water supply line between the cylinder and the
hand pump. This can be purchased locally. You will need to
buy the same amount of pipe as you did pump rod. The pump
rod is installed inside this pipe.
THAT'S IT! That is everything you will need for your system.
Instructions will come with your order.
