Gland packing
design
Many industrial type materials (sealants,
adhesives, inks, etc.) display a tendency to
dry out and build up on pump plunger rod.
Hard, dried out materials cause gland
packing to wear rapidly, resulting in leakage
and pump failure. Also problematic is gland
seal exposure to high pressure and in
particular, to pressure fluctuation during
pump operation (stroke change over).
The gland packing design of Pile Driver III
pumps addresses both problems.
Externally, a special spring-type metal
wiper (5) scrapes built-up and dried material
from pump plunger before it is pulled
through gland packing on down stroke. In
order to help metal wiper work longer and
more efficiently, lubrication well of pump
should be filled with a fluid compatible with
material being pumped.
Do not fill lubrication well to full capacity,
as reciprocating movement of pump may
draw fluid into airmotor.
Internally, a special protection sleeve (9)
with concentric grooves creates a labyrinth
path that reduces effects of internal pressure
and stroke change over fluctuation on gland
seal. In addition, a second internal wiper
limits gland seal exposure to pumped
material.
The combination of metal wipers and
protection sleeve results in longer gland seal
life and helps to prevent leakage.

Attach airmotor to
pump tube
1 Tightly attach tie rods to airmotor
(use short threaded end of tie rods).
2 Mount airmotor on top of pump tube
outlet and tightly connect
coupling nut (2) to airmotor piston rod.
3 Hand tighten tie rods to pump tube with
four nuts supplied with airmotor.
4 Slowly cycle pump several times, using
just enough air pressure to operate
pump without stalling.
5 Stop pump on an “up” stroke and tighten
four nuts to securely fasten airmotor to
pump tube.
Operation
precautions
• Use Lincoln replacement parts to assure
compatible pressure rating.
• Heed all warnings.
• Material hoses and other components
must be able to withstand fluid pressures
developed by pump.
• Do not operate pump continuously at
speeds in excess of 75 cycles per minute.
• Disconnect air line from pump airmotor
when system sits idle for long
periods of time.
• Do not service or clean pump, or remove
fluid hose or gun from unit without first
disconnecting air lines and bleeding
pressure from system.
• Check static wire connection with
ohmmeter. Place one probe on one
hose fitting and other probe on other
hose fitting. Proper grounding through
hose is good when reading is obtained
on ohmmeter.
• Do not pump, flush or recirculate volatile
solvents without adequate ventilation.
Failure to comply may result in fire.
• Keep solvents away from heat, sparks and
open flames. Keep containers closed when
not in use.
NOTE
Install pump in upright position.
Use model 83727 stand pipe for bulk
material dispensing.
Locate pump as close to tank as possible
with minimum 3 in (76 mm) ID inlet hose
or pipe.
WARNING
Do not exceed stated maximum working
pressure of pump or of lowest rated
component in system.
Do not alter or modify any part
of equipment.
Do not operate equipment with
combustible gas or fuel, gasoline, diesel fuel,
kerosene, etc.
Do not attempt to repair or disassemble
the equipment while the system is
pressurized.
Securely tighten all fluid connections
before using equipment.
Read and follow fluid manufacturer’s
recommendations regarding fluid
compatibility, and use of protective clothing
and equipment.
Check all equipment regularly and
repair or replace worn or damaged
parts immediately.
Check equipment for proper operation
before each use. Safety devices should be in
place and operating properly.
Failure to comply may result in equipment
damage and/or serious personal injury, fire,
explosion or property damage.
WARNING
Do not operate pump without proper
grounding. Pump, dispensing valve and
containers must be grounded when handling
inflammable fluids, such as petroleum
products, paints, lacquers, etc. and wherever
discharge of static electricity is a hazard.
Failure to comply may result in fire or
explosion.
NOTE
Do not allow pump to operate when out of
material.

Pump prime
To begin operation, pump has to be primed
with pumped material. Pile Driver III pump is
a double acting (pumps material on “up” and
“down” stroke) positive displacement
reciprocating pump and intakes material
only on the “up” stroke.
To prime pump:
1 Open output line (material valve) and
slowly open air supply valve until
pump starts.
2 Allow pump to cycle very slowly until all
air is pushed out of lines and material
fills up pump and lines.
3 Close output line (material shut-off
valve). Pump should stall against
pressure.
4 If pump fails to prime properly, open
bleeder valve (12) slightly to expel
trapped air. Tightly close valve at first
sign of material coming out of valve.
When repairing pump, reassemble in
vertical position to achieve optimum life of
seals and packings.
Outlet position
adjustment
Position of pump outlet may be adjusted by
loosening three set screws (30) and rotating
pump tube outlet into position desired.
Tighten screws to 25 lbf-ft (18,4 Nm).

Troubleshooting
Condition Possible cause Corrective action
Pump does not operate. Restricted or inadequate air supply. Check air supply pressure and air hose
diameter for minimum air supply
hose diameter.
Obstructed material output. Check output line for restrictions.
Pump speeds up or runs erratically. Pump is not primed. Prime pump (†Pump prime, page 6).
Insufficient material supply. Refill material supply.
Material is too heavy for priming. Decrease output with material valve
Increase pressure to pressure primer
(if in use). Check for inlet restrictions.
Pump operates on “down” stroke only
(missing “up” stroke).
Worn or damaged piston U-cup (23)
or piston check (20, 24).
Check and replace if needed.
Pump operates on “up” stroke only
(missing “down” stroke).
Worn or damaged inlet check (20, 27). Check and replace if needed.
Insufficient material supply. Pump is not
taking in enough material to dispense on
both strokes.
Check inlet for restrictions.
Decrease output with material valve.
Pump is operating but not
dispensing material.
