INSTALLATION INSTRUCTIONS
1. Pump Location
The John Blue Squeeze Tube Pump should always be mounted even with or lower than the
fertilizer tank for accurate metering. The pump can be mounted to any flat surface. There is no
need to have the pump mounted in the middle of the equipment. The pump creates enough
pressure to place it at the end of the implement. Make sure all connections, filters and
couplings are tight so the pump can lift and pull product to it. The speed should not exceed 100
RPM.
Any shaft that turns in ratio to the ground can be considered to drive the pump. The pump only
requires a small amount of torque to turn it. Typically it is one of the seed shafts, which can be
used, but try to have it before the transmission so that if you change seed population the
fertilizer rate remains unchanged.
2. Pump Mounting
Two angle iron bars with holes are supplied and can be bolted to each side of the pump. Undo
the frame end plate bolts, match up the holes in the angle iron and retighten the nuts. The
hook bolts supplied can be used over the angle iron or the frame channel to bolt the pump to
your equipment.
3. Pump Mounting of Combination Pumps
The mounting of combination and double pumps
is not different than what is described above as to
location and drive system. The exception is when
you want
to keep the starter fertilizer always at the same
rate and want to use the coned sprockets to
vary the nitrogen rates. Figure 1 shows this
type of system, where you drive both sides of
the pump.
(Picture A)
Special plumbing is needed because both manifolds will have product flowing to it. If two
different products are to be pumped, two independent plumbing systems must be used. As the
center manifold is fed through the chain it is important to check the clearance with the hose and
fittings used.
Note: The sprockets that come on
the side across from the coned
sprockets are not used and must
be removed.
(FIGURE 1)

5
Tube tension needs to be put on both rollers, see section 7. Rates of application are the same as
for a single pump and are detailed in the rate chart. Remember, “L” tubes apply twice as much
product as “B” tubes at the same RPM. You must calculate the effect of the sprockets for both.
4. Hose Arrangement
When you do not require all the squeeze tubes to be used, remove the tubes uniformly starting in
the middle taking onetube first from one side then the other. The plugs supplied should be installed
in the manifold in place of the tubes.
5. Plumbing
John Blue Company recommends using 1-1/4” ID hose between the tank and the pump. Smaller lines
may starve the pump reducing the application rate. Filters are recommended, but when rates are
lower than anticipated many times it is a filter that is clogged or the strainer mess is too small.
Aloop at the end of the delivery line will prevent product from draining as it will stop air from entering
the hose to displace product. Since the pump is holding the product all that will drain is the small
amount that can be displaced by air up to the loop in the line. A ball valve should be used to shut
off any system when not in use to ensure no leakage occurs.
Always use Teflon tape or pipe joint compound on all connections. Never over tighten fittings as this
may cause them to crack. Check the squeeze tube screw clamps, as they may need to be retightened.
The screw clamps when installed on new squeeze tubes can cause the tubes to extrude slightly
under pressure of the clamp. As this occurs over time it is best to retighten the screw clamps slightly
before starting a new pump. Only retighten the screw clamps on the inlet side where the tube
is attached to the manifold. Do not retighten the fittings in the manifold; they are sealed at
the factory.
6. Chain Adjustment
The chain between the John Blue Squeeze Tube coned sprockets is adjusted by removing the
master link and moving the chain to the correctposition.
7. Tube Tension Adjustment
The oval-shaped tubes need to be stretched
across the four rollers in order to perform
efficiently. To tighten the tension on the tubes
insert the handle, supplied with the pump, on
the tube tension bar #1 (see drawing). Using
the handle pull forward toward the manifold #2
until the latch #3 engages into the notch on the
frame end plate. When engaged the outlet fitting
rack #4 will have been pushed forward and will
stay in the forward position. There are two
notches on the frame end plate, use only the
minimum tension to stop product from flowing
through the pump. For new pumps this is the
first notch. The pump will not work without tube
tension. When the pump is not being used, the
tension should be taken off the tubes by releasing
the latch #3.

6
Check the filter size to make sure product can flow easily, open the ball valve and check for
leaks. Before going to the field, always check the rates as there can be variables that can cause a
difference between calculated rates and actual rates.
8. Hydraulic Pumps
Tractor hydraulics can be used to power the John Blue Squeeze Tube Pumps. Hydraulic pumps
come with the hydraulic motor and control valve, which is connected with standard hose and
fittings. There are many power take-off options associated with different tractor manufacturers
so it is best to consult your local tractor supplier for proper installation.
MAINTENANCE
When the pump is not in use, always take the tension off the tubes by releasing the latch. See
#7, Tube Tension Adjustment instructions.
DRIVE FACTOR EQUATIONS
The information and charts are provided to assist you in the initial set up of your squeeze tube
pump. The attached information provides the basic calculations for a squeeze pump
installation. This information is also available online at www.johnblue.com under “Calculate your
Rates.” It is highly recommended that you take advantage of the website to assist you in your
rate calculations.
COMPLETE THE FOLLOWING FOR ALL APPLICATIONS
Row Spacing =actual distance in inches between each point of application.
GPA Desired = amount of material to be applied in gallons per acre (GPA).
Wheel Diameter = ground wheel diameter in inches.
(If using a rub wheel measure the rub wheel diameter.)
Speed = the speed you will be traveling in MPH.
Step 1 Finding Pump RPM
.134 for B pump or
xx .067 for Lpump =
Row Spacing GPA Desired RPM of Mainshaft
Example: Row spacing is 12 inches; you want 29 GPA using an “L” pump.
Correct answer: 12 x 29 x.067 = 23 RPM (Round off to whole number)
Never operate the pumps over 100 RPM, this is affected by ground speed; see “Adjustment for
Speed.”
** For Hydraulic Driven Pumps; see “Adjustment for Speed.” **

Step 2 Finding Sprocket Ratio
The sprocket ratio is used to
determine the size sprocket needed
on the ground wheel and pump
jackshaft.
1681 =
RPM Main Shaft x Wheel Diameter Ratio Pump Jackshaft to
Ground Wheel
Example: RPM is 23 (from step 1) and your wheel diameter is 30 inches.
Correct answer:1681 = 2.4: Divide 1681 by 23 then divide the answer 73 by 30 = 2.4
(23)(30)
Step 3 Finding Actual Sprockets to Use
Count the number of teeth on the
driving sprocket you are using. The driving x =
sprocket is the sprocket on the ground
wheel, rub wheel or existing shaft.
Ratio from Step 2Teeth on Driving Teeth on Jack
Sprocket Shaft Sprocket
Example: The number of teeth on your driving sprocket is 10.
Correct Answer: 2.4 x 10 = 24 tooth sprocket on pump’s jackshaft.
Note that you may also use the coned sprockets to adjust the sprocket ratio between the
Jack (input) shaft and Main shaft according to this chart:
Sprocket Pair #
Main shaft speed vs. Jack
1
0.45
2
0.60
3
0.77
4
1.00 (default)
5
1.28
6
1.66

2.20
Direct Couple to Existing Shaft
When you want to turn the pump’s jackshaft directly from an existing shaft, complete Step 1 to
find the main shaft RPM for the desired GPA. At the desired speed of application count the RPM of
the existing shaft and divide that number by the mainshaft RPM to find the sprocket ratio.
RPM of Existing Shaft =
Mainshaft RPM from Step 1Ratio Jackshaft to Existing Shaft
Example: RPM from Step 1 is 40 and your shaft turns 80 RPM’s at 5 MPH.
Correct Answer: 80 divided by 40 =2.0 This is the ratio between the pump’s jackshaftand your
driving shaft. Use this factor in Step 3above to select the correct cone sprocket position.
Adjusting for Speed
All calculations are based on 5 MPH. You need to adjust for the speed you plan to travel for
hydraulic driven pumps to get the right RPM. For ground driven pumps we need to insure that the
pump operates fewer than 100 RPM’s at the speed you travel. Take the RPM from Step 1 or if you
use the coned sprockets the adjusted RPM and multiply as follows:
3 MPH
RPM x 0.6 =
7 MPH
RPM x 1.4 =
4 MPH
RPM x 0.8 =
8 MPH
RPM x 1.6 =
5 MPH
RPM x 1.0 =
9 MPH
RPM x 1.8 =
6 MPH
RPM x1.2 =
10 MPH
RPM x 2.0 =
