GLAND PACKING DESIGN*
Many industrial type materials (sealants, adhesives, inks, etc.)
display a tendency to dry out and to build up on the pump
plunger rod. These hard dried out materials cause the gland
packing to wear rapidly, resulting in leakage and ultimate pump
failure The second problem is the gland seal exposure to high
pressure and in particular, to pressure uctuation 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 (Item 5) scrapes
built-up and dried material from the pump plunger before it is
pulled through the gland packing on the down stroke. In order
to help the metal wiper work longer and more efciently, the
lube well of the pump should be lled with a uid compatible
with the material being pumped.
Do not ll the lube well to full capacity, as the reciprocat-
ing movement of the pump may draw uid into the
airmotor.
Internally, a special Protection Sleeve (Item 9) with
concentric grooves creates a labyrinth path which reduces the
effects of internal pressure and stroke change over uctuation
on the gland seal. In addition, a second internal wiper limits
gland seal exposure to the pumped material.
The combination of the metal wipers and the protection sleeve
results in longer gland seal life and prevents
leakage.

ATTACHING AIRMOTOR TO PUMPTUBE
1. Tightly attach tie rods to the airmotor (use short threaded
end of the tie rods).
2. Mount airmotor on top of the pumptube outlet and tightly
connect Coupling Nut (Item 2) to airmotor piston rod.
3. Hand tighten tie rods to the outlet with four nuts supplied
with airmotor.
4. Slowly cycle the pump several times, using just enough air
pressure to operate the pump without stalling.
5. Stop the pump on an “up” stroke and tighten the four nuts
to securely fasten the airmotor to the pumptube.
• Check continuity (a good static wire connection) with an
ohmmeter. Place one probe on one hose tting and the
other probe on other hose tting, continuity or proper
grounding through hose is good when a reading is obtained
on the ohmmeter.
• PREVENT FIRES. When pumping, ushing or recirculating
volatile solvents, the area must be adequately ventilated.
• Keep solvents away from heat, sparks and open ames.
Keep containers closed when not in use.
• Use Lincoln replacement parts to assure compatible pres-
sure rating.
• HEED ALL WARNINGS.
• Be sure material hoses and other components are able to
withstand uid pressures developed by this pump.
• Do not operate pump continuously at speeds in excess of
75 cycles per minute.
• Disconnect air line from pump air motor when system sits
idle for long periods of time.
• SERVICING. Before servicing or cleaning pump, or remov-
ing uid hose or gun from a unit that has been used, be
sure to disconnect air lines and carefully bleed pressure off
of the system.
Keep hands away from pump inlet while airline is
connected. Do not operate pump unless it is rmly mounted
on to Pressure Primer or Standpipe and area around pump
inlet is clear of obstructions.
PREVENT STATIC SPARKING.
If static sparking occurs, re or explosion could
result. Pump, dispensing valve, and containers must
be grounded when handling inammable uids, such
as petroleum products, paints, lacquers, etc. and
wherever discharge of static electricity is a hazard.
PUMP PRIMING
To start operating, the pump has to be primed with pumped
materials. The Pile Driver III pump is a double acting (pumps
material on up” & down” stroke) positive displacement recip-
rocating pump and as such intakes material only on the “up”
stroke.
To prime pump, open output line (material valve) and slowly
open air supply valve until pump starts. Allow pump to cycle
very slowly until all air is pushed out of lines and material lls
out pump and lines. Close output line (material valve) - pump
should stall against pressure.
If pump fails to prime properly, open Bleeder Valve (Item 11)
slightly to expel trapped air and at the sign of material coming
out of the valve, close it tightly.
DO NOT allow pump to operate when out of material.
NOTE: Pump should be installed upright for operation.
Use Model 83727 Stand Pipe for bulk material dispensing.
Locate pump as close to tank as possible and use a minimum
of 3 in (76 mm) I.D. inlet hose or pipe.
FAILURE TO HEED THE FOLLOWING WARNINGS INCLUDING MISUSE, OVER PRESSURIZING, MODIFYING PARTS,
USING INCOMPATIBLE CHEMICALS AND FLUIDS, OR USING WORN OR DAMAGED PARTS, MAY RESULT IN
EQUIPMENT DAMAGE AND/OR SERIOUS PERSONAL INJURY, FIRE, EXPLOSION OR PROPERTY DAMAGE.
• Do not exceed the stated maximum working pressure of the pump or of the lowest rated component in your system.
• Do not alter or modify any part of this equipment.
• Do not operate this equipment with combustible gas or fuel, gasoline, diesel fuel, kerosene, etc.
• Do not attempt to repair or disassemble the quipment while the system is pressurized.
• Make sure all uid connections are securely tightened before using this equipment.
• Always read and follow the uid manufacturer’s recommendations regarding uid compatibility, and the use of protective
clothing and equipment.
• Check all equipment regularly and repair or replace worn or damaged parts immediately.
• Always check equipment for proper operation before each use, making sure safety devices are in place and operating
properly.

NOTE: Pumps are factory tested with light oil and some of
it is left in to protect pump parts during storage and
transportation. To prevent contamination of material
to be pumped, ush pump before using.
OUTLET POSITION ADJUSTMENT
The position of the pump outlet may be adjusted by
loosening the three screws (Item 26) and rotating the pump-
tube outlet into the position desired. Retighten the screws to
25 ft/lbs.
©When repairing pump, reassemble in vertical position to
achieve optimum life of seals and packings.

Obstructed material output. Check output line for restrictions.
Erratic or accelerated operation. Pump is not primed. Prime pump (see "Pump Priming"
instructions).
