Scope Of This Manual:
This manual describes the
LINC82 Chemical Metering Pump,
which is a beam-operated plunger
pump.
Installation:
This pump requires a flooded
suction and must be located lower
than the chemical supply tank.
Vertical installation of the pump
body is required.
1. Bolt or weld the pump
mounting bracket from the
mounting kit to the steel
base of the pumping unit. It
is recommended that the
chemical pump is mounted
so that the cable (wire rope)
is as close to vertical as
possible.
2. Attach the cable assembly
from the mounting kit to the
walking beam near the
fulcrum point of the pumping unit with the beam
clamp provided. Ensure
that the cable does not
interfere with the walking
beam supports.Refer to
Figures 4 or 5 of this manual
for desired stroke length.
3. Attach the cable to the
turnbuckle of the chemical
pump using the cable clamp
provided (fig. 1, item 23).
4. Adjust the cable length to
obtain desired approximate
plunger stroke length. Final
adjustment of the stroke may
be obtained with the turnbuckle.
5. Secure the turnbuckle
position with locknuts (fig. 1,
items 22 & 24).
Caution: Care must be exercised
to assure that the cable is of sufficient length and is attached to the
walking beam at a point so that the
plunger stroke does not exceed 1".
6. Connect the suction line from
the chemical drum through a
filter or strainer to the suction
check valve (fig. 1, item 14).
7. Connect the discharge line
from the discharge check
valve to the desired location
(fig. 1, item 15).
Note: An inline check valve at
the point of injection is recommended to prevent back flow to the
pump during shutdown or servicing.
Start-Up:
1. To prime the pump, loosen
the bleed screw to vent the
trapped air allowing the liquid
(chemical) to flow into the
pump chamber (fig. 1, item
12). Tighten the bleed screw.
2. Start the pump and run for a
minimum of one minute.
Then, open the bleed screw
again to evacuate all the
remaining air or gas from the
pump chamber.
Refer to Figures 4 or 5 for desired
injection rate. Determine the stroke
length by adjusting the cable and
turnbuckle. Stroke length must be
adjusted when changes are made to
the pumping unit cycles per minute
to maintain a fixed rate of flow.
If a drum gauge has been installed, depress test level on drum
gauge to cause the pump suction
to be drawn from the gauge glass.
With a stop watch, note the change
of liquid level on drum gauge glass
for one minute. Most drum gauge
scales are calibrated directly in
quarts per day for one minute of
operation. The liquid level remaining in the drum is displayed on the
gauge with the test level released.
Maintenance:
Pump parts are subject to normal
wear and must be inspected and replaced as necessary. Inspection and
maintenance frequency depends on
severity of service conditions. Instructions are given in this section
for maintaining the pump as units;
i.e. suction check valve, discharge
check valve and plunger packing.
Suction Check Valve,
Figure 1, item 14 & Figure 3:
1. Assure that the pump is
isolated from the rest of the
system.
2. Disconnect the piping from
the check valve.
3. Unscrew the check valve
body (fig. 3, item 1) from the
pump lower housing (fig. 1,
item 13).
4. Remove and discard the
o-rings (fig. 3, items 3 & 4).
5. Inspect the ball for damage
(fig. 3, item 2). Replace if
necessary. Reassemble the
check valve using new o-rings.
If the seat o-ring is Teflon,
install it into the check valve

body (fig. 3, item 1) and "peen"
the ball onto the seat to
ensure proper sealing.
6. Install the repaired suction
check valve into the pump
body. Tighten securely.
7.Reconnect the suction piping.
Discharge Check Valve,
Figure 1, item 15 & Figure 2:
1. Assure that the pump is
isolated from the rest of the
system.
2. Disconnect the piping from
the check valve.
3. Unscrew the check valve
body (fig. 2, item 1) from the
pump lower housing (fig. 1,
item 13).
4. Remove and discard the
o-rings (fig. 2, items 4 & 5).
5. Inspect the ball and spring
(fig. 2, items 2 & 3) for damage. Replace if necessary.
Reassemble the check valve
using new o-rings. If the seat
o-ring is Teflon, install in into
the pump lower housing (fig.
1, item 13) and "peen" the
ball onto the seat to ensure
proper sealing.
6. Install the repaired discharge
check valve into the pump
lower housing. Place the ball
on the o-ring seat followed by
the spring (small end of the
spring toward the ball) and
screw the discharge check
valve body into the pump
lower housing. Tighten
securely.
7. Reconnect the discharge
piping.
Plunger and Plunger Seal,
Figure 1, item 6 & 16:
1. Assure that the pump is
isolated from the rest of the
system.
2. Remove the pin retainer and
pins separating the plunger
assembly from the beam (fig.
1, items 4 & 5). Remove the
retaining ring and loosen the
set screw and separate the
swivel ring (fig. 1, items 7, 9
& 8) from the packing block.
3. Grasp the plunger assembly
(fig. 1, item 6) and pull up out
of the packing block (fig. 1,
item 11) to remove. Inspect
the plunger for wear, especially longitudinal grooves.
Replace the plunger assembly
if necessary.
4. With a pipe or strap wrench
separate the packing block
(fig. 1, item 11) from the lower
housing (fig. 1, item 13).
5.Remove the plunger seal and
seal back-ups, where used,
from the lower housing (fig.
1, items 16 & 13). Carefully
remove the seal back-up and
seal. Inspect for wear or
deterioration from being
attacked by the chemical the
pump is pumping.
6.Replace the plunger seal and
plunger seal back-ups if
needed (see parts lists on
page 9). If the plunger seal
is the o-ring type, it should
be installed with a plunger
seal back-up on each side of
the o-ring. If the plunger seal
is of the Uniseal type, it
should be installed with the
expander ring down toward
the lower housing. Extreme
care should be taken not to
scratch or distort these parts.
7. After the seal has been
replaced, lubricate with a light
oil to protect against possible
damage during assembly.
8.Screw the packing block onto
the lower housing and tighten
securely. Slide the plunger
assembly into the packing
block and down into place.
Install the swivel ring with the
retaining ring and beam with
the pin and pin retainer. See
step 2 above under this section.
9. If the bleed screw has been
removed, install and tighten
securely.
Plunger and Plunger Seal
Lubrication:
1. Remove the plug from the
pump body (fig. 1, item 10).
2. Add silicone base lubricant
(Dow Corning DC-7, part
#10354) or equal into the port
where the plug was removed.
Approximately 0.5cc will be
required for each refill.
Replace the plug.
Note: Do not use a grease gun
or any metal tool to insert the lubricant into the pump to prevent damage to the plunger or plunger seal.
3. Silicone lubricant should be
added every 4 - 6 weeks
depending upon operation
conditions.
