Scope Of This Manual:
This manual describes and
provides instructions and parts list
for the LINC86 Chemical Metering
Pump. These pumps are electri-
cally operated plunger and/or
bellows pumps.
Installation:
This manual assumes that the
motor that drives this pump has
been connected to the power
source by a qualified electrician and
meets all the required electrical
standards of the area where it is
installed.
These pumps require a flooded
suction and must be located lower
than the chemical supply tank.
Horizontal installation of the pump
head assembly is required.
1. Connect the suction line
through a filter or strainer to
the suction check valve .
2. Connect the discharge line
from the discharge check
valve to the desired location.
Note: An inline check valve is
recommended at the point of injec-
tion to prevent back flow to the
pump during shutdown or servicing.
Caution: A pressure relief valve
must be installed in the discharge
line and set at 10 to 20% above the
normal discharge pressure to pre-
vent dead-heading and over pres-
suring the pump. This pump is ca-
pable of producing pressures that
will rupture the discharge line. The
output of the relief valve should be
connected back to the suction line
or the chemical supply tank.
3. Prime the pump by loosen-
ing the bleed screw (fig. 1,
item 24. Allow the liquid
(chemical) to flow into the
pump chamber, venting the
trapped air or gas.
4. Start the pump and run for
sufficient time for the pump
to discharge continuously
and smoothly. Close the bleed
screw.
5. After the pump has been
operating for a period of time
and does not seem to be dis-
charging the proper volume
per stroke, loosen the bleed
screw slightly until all en-
trapped air or gas is evacu-
ated from the pump cham-
ber. Tighten the bleed screw.
6. To vary the volume that the
pump delivers on each stroke,
loosen the set screw (fig. 1
item 4, ) and rotate the stroke
adjustment collet (fig. 1, item
18). Clockwise rotation will
increase the volume and
counterclockwise rotation will
reduce the volume. The
stroke may be adjusted while
the pump is running. The
edge of the collet aligns with
an indicator that shows per
centage of full stroke.
7. After the collet has been
adjusted so that the pump
is delivering the desired vol-
ume, tighten the set screw
to lock the collet in place.
Maintenance:
Refer to all sectional drawing and
parts list in this manual. All repairs
should be performed in a clean en-
vironment.
The following steps must be taken
before proceeding with any main-
tenance operations.
Removing the Pump from Ser-
vice:
1. Turn off the electrical power
to the pump and make sure
it is locked out.
2. Close the upstream and
downstream valves on the
chemical lines.
3. Open the bleed screw to
release the pressure in the
pump.
4. Disconnect the suction and
discharge lines from the
check valves.

1. The entire pump head
assembly may be removed
as a unit.
2. Loosen the set screw (fig. 7,
item 11) on the boss of the
drive housing assembly.
3. Unscrew the pump head
assembly by turning the hex
mounting adapter (fig. 1,
item 19) counterclockwise.

To replace the Plunger:
1. Loosen the four set screws
around the head spacer
(fig. 1, item 4) closest to the
hex mounting adapter (fig. 1,
item 19). The pump head
may now be removed with-
out removing the packing.
2. Pull the assembly straight
out, away from the adapter,
being careful not to damage
the plunger.
3. Drive out the pin and remove
the plunger (fig. 1, items 7
& 8). Replace the new
plunger and pin.
To replace the Power Plunger or
Spring, fig. 1, items 1 & 2:
1. Remove the retaining ring
(fig. 1, item 6).
2. Pull the power plunger out of
the mounting adapter and
collet assembly (fig. 1, items
19 & 18).
3. Screw the collet off of the
mounting and inspect the
seal (fig. 1, item 25). Replace
any of the parts that are worn
or damaged and reassemble.
4. After the parts have been
reassembled, compress the
spring completely and let it
return pulling the retaining
ring up against the collet
making certain there is no binding.
To replace the Seals:
1/4", 3/8" & 1/2" Only
1. Loosen the four cap screws
that attach the end cap to the
seal body (fig. 1, items 11,
12 & 16).
2. Separate the seal body from
the head spacer by remov-
ing the four set screws
(fig. 1, item 4) nearest the
fluid end of the pump head
assembly.
3. Push the old seals, spacer
and split bushing out of the
seal body (fig.1, items 23, 22 & 21).
Note: These seals can either be
uniseals (seal back-up built into the
seal) or seals with separate back-
up rings.
4. Lubricate the new seals to
prevent damage during
installation.
5. Replace the seals by first
placing the split bushing into
the seal body followed by the
spacer and seal (expander
ring side facing out toward
the fluid end of the pump).
If a seal with a backup is
being used, the back-up
goes in first.
6. Place this assembly over the
plunger and reattach to the
heads spacer with the four
set screws.
7. Install a new o-ring (fig. 1,
item 15) in the seal body and
attach the end cap with the
four cap screws.
To Replace the Seals:
3/4" & 1" Only
1. Remove the four screws
that attach the end cap to
the seal body (fig. 4 item 20).
Pull the end cap out of the
seal body.
2. Remove the four screws
that attach the head spacer
to the seal body (fig. 4 item
24). Pull the head spacer
away from the seal body.
3. Pull the center ring (fig. 4
item 23) out of the seal
body.
4. Remove the plunger seals
(one in each end of the seal
body) and the seal backup
(one per seal if used) from
the seal body, being care
ful not to scratch the wall of
the seal gland. The seal
spacer (fig. 4 item 13) can
remain in the seal body.
5. Before reinstalling the
plunger seals, lubricate
them and their glands with
a light grease. Install the
seals with their lips facing
the end of the pump that is
equipped with check
valves. If the seals that are
being installed require seal
backup rings, install the
backup rings behind the
heel of the seal.
6. Using the screws that were
previously removed,
reattach the head spacer
and the end cap to the seal
body.
7. Lubricate the plunger be
fore reinserting it into the
seal body.
8. Remove 1/8" npt lube plug
(fig. 4 item 14). Fill with
30wt motor oil or silicone
grease. Replace plug.

To replace or repair the Suction
and/or Discharge Check Valve:
Two-Piece, fig. 1, items 10 & 13,
fig. 2, items 6 & 17, fig. 5 & 6:
Field repair of check valves
is not recommended. However, if
the checks are to be repaired, the
repairs should be done in a clean
environment that has the necessary
equipment to check the valves for
leakage after they are repaired.
The discharge check valve con-
tains a spring to hold the ball against
the seat. In the suction check valve,
the ball floats freely.
To repair the Check Valves:
1. Separate the two halves for
the check valve (fig. 5 & 6,
items 1 & 4).
2. Replace the o-rings, ball and
spring as required (fig. 5 & 6
items 2, 3, 5 & 6). In the
majority of the check valve
the seat o-ring will be Teflon
(fig. 5 & 6, item 2). This o-
ring may be removed, turned
around and reused if a new
o-ring is not available. During
this procedure, extreme care
should be exercised. The
ball should be "peened" on
the Teflon seat to ensure
proper sealing (fig. 5 & 6,
items 2, 5 & 1).
3. Connect the outlet of the
check valve to an air pres-
sure source and apply 10
psig. Place the inlet of the
check valve into water or
bubble test fluid. If bubbles
appear, reset the ball to the
seat o-ring and retest. In-
crease the air pressure to
100 psig and again check for
leaks as above.
4. Ensure that the proper flow
direction, as marked on the
valve body, is observed
when installing or replacing
the check valve.
5. Install the repaired check
valves into the pump body
and tighten securely.
Optional Bellows Pump Head
86-20 & 86-30
3/8" & 1/2" Plungers:
(figure 2)
To replace the Seals, Split
Bushings & Bellows:
1. Remove the entire bellows
pump head assembly from
the drive housing assembly
as previously described for
the standard pump head
assembly.
2. Loosen the four set screws
(fig. 1, item 4) that mount
the bellows seal body to the
head spacer (fig. 1, items
16 & 17). Pull the head
spacer assembly, with the
plunger attached (fig. 1,
item 8), out of the bellows
seal body. Loosen the six
cap screws (fig. 2, item 13)
that hold the bellows seal
body to the bellows housing
(fig. 2, item 8). Separate
the seal body and housing.
3. The split bushings, the
spacer and seals (fig. 2,
items 14, 15 & 16) can be
removed from the bellows
seal body by pushing the
round shank of a drill bit
through the plunger hole in
the bellows seal body. Use
a 25/64" diameter bit for the
3/8" plunger pump and a
33/64" diameter bit for the
1/2" plunger pump.
Note: Be careful not to scratch
the bore that houses the seals.
4. Remove the bellows (fig. 2
item 10) from the bellows
housing (fig. 2, item 8).
The bellows will be tight in
its housing and may be hard
to remove. Do not dam
age the sealing surfaces
while removing the bellows.
5. To reassemble the pump,
position the bellows hous-
ing in the vertical position,
possibly in a vise. Start by
placing the bellows spring
and bellows (fig. 2, item 9
& 10) in the bellows hous-
ing. Then, install the bel-
lows retainer and o-rings
(fig. 2, items 12, 2, 3, 4, &
5). Lubricate the o-rings be
fore installation.
6. Fill the bellows with 10W-30
or 5W-30 motor oil depend-
ing on temperature condi-
tions using the following
procedure.
7. Slowly fill the bellows cavity
until oil is flush with the top
of the bellows. Air will be
trapped in the bellows con-
volutions.

Note: It is important to remove
this air. Insert a small wire or simi-
lar item into the cavity and gently
stir the oil in the convolutions to
release any air. If necessary, add
additional oil until it is flush with
the top of the bellows.
8. Install the split bushings,
spacer and seals in the bel-
lows seal body as shown in
Figure 2. The lips of both
seals should point toward
the bellows. Lubricate the
parts before installation.
Insert the plunger (with the
head spacer assembly
attached) into the bellows
seal body, through the parts
that have just been installed.
9. Fill the small cavity between
the seal lip that shows in
the end of the bellows seal
body and the plunger with
silicone grease. This will
eliminate an air pocket
when the pump is fully
assembled. Install the
plunger (with the seal body
assembly and the head
spacer assembly attached)
into the bellows housing
and bellows. Oil will oveflow.
10. Install and tighten the six
cap screws (fig. 2, item 13).
The screws will need to be
tightened several times
because of the cold flow of
the bellows flange.
11. Screw this entire assembly
into the drive housing and
tighten the set screw that
holds it in place.
Drive Housing Assembly:
The shaft bearing and cam bear-
ing in the drive housing assembly
(fig. 7, items 5 & 10) are roller bear-
ings which will provide a long,
trouble-free life.
If for some reason the bearings
are to be replaced,:
1. Remove the pump head
assembly or assemblies
from the drive housing.
2. Remove the drive housing
from the pump base and
remove the coupling half
from the drive cam shaft (fig.
7, item 7). Remove the eight
screws and bearing plate
(fig. 7, items 3 & 4) on the
shaft side of the drive hous-
ing.
3. Remove the cam shaft and
bearing mounting plate from
the drive housing.
4. Remove the eight cap screws
from the bearing mounting
on the outside of the drive
housing and remove this
plate from the drive housing.
The bearing in the mounting
plates are pressed in and
may have to be removed
with a bearing puller. The
bearing plate that has the
opening for the shaft, also
has a shaft oil seal (fig. 7,
item 8). Inspect this seal and
replace if needed.
To remove the Bearing from the
Cam Shaft, fig. 7, items 10 & 7:
1. Remove the snap ring (fig.
7, item 9) from one side of
the bearing and pull the
bearing off of the cam.
2. Replace with a new bearing
and snap ring if needed.
3. Scrape the old gaskets
from the drive housing and
bearing mounting plates.
Clean these surfaces with a
solvent to remove the old
gasket compound.
4. Using a new gasket and a
gasket compound (Permatec
Form-A-Gasket #2) replace
the blind bearing plate with
new bearing installed with
the eight cap screws. From
the other side of the drive
housing case, place the
other end of the cam shaft
with new bearing in place
into the inner bearing race.
5. Again, using a new gasket
and gasket compound,
place the other bearing
mounting plate with new
bearing and oil seal over the
shaft and fasten to the drive
housing with the eight cap
screws. This mounting plate
has an 1/8" socket head pipe
plug in it which should be at
the very bottom of the as-
sembly when installed.
6. When in operation, the drive
housing should always be
properly filled with oil. The
oil used in the drive housing
should be high quality 90W
motor oil.

7. Replace oil every 4000
hours by draining the case
through the drain plug (fig. 7,
item 17) and refilling through
the oil fill/vent cup (fig. 7, item
14). Fill housing to the level
that the oil will run out the
1/8" NPT hole in the back
bearing mounting plate
when the socket head plug
is removed. When full to this
point, replace the plug.
Note: See Figure 8 for pumps
that are equipped with more than
two plunger heads.
