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
