WARNING
Do not allow any body part
to be trapped by equipment.
Body parts can be crushed
by subassemblies during
operation.
Failure to comply may result in death
or serious physical injury.
WARNING
Do not allow fluid to leak
onto floor when operating
equipment. If spill occurs,
clean any fluid on floor before continuing
operation.
Failure to comply may result in death
or serious personal injury.
WARNING
Do not use this equipment to supply,
transport, or store hazardous
substances and mixtures in accordance
with annex I part - of the CLP
regulation (EG /) or HCS 

shown:
Safety*
The assembly must be installed, maintained
and repaired exclusively by persons familiar
with the instructions.
Always disconnect power source
(electricity, air or hydraulic) from the
equipment when it is not being used.
This equipment generates high pressure.
Extreme caution should be used when
operating this equipment as material leaks
from loose or ruptured components can
inject fluid through the skin and into the
body. If any fluid appears to penetrate the
skin, seek attention from a doctor
immediately. Do not treat injury as a simple
cut. Tell attending doctor exactly what type of
fluid was injected.
Any other use not in accordance with
instructions will result in loss of claim for
warranty or liability.
• Do not misuse, over-pressurize, modify
parts, use incompatible chemicals, fluids,
or use worn and/or damaged parts.
• Do not exceed the stated maximum
working pressure of the equipment or of
the lowest rated component in your
system.
• Always read and follow the manufacturer’s
recommendations regarding fluid
compatibility, and the use of protective
clothing and equipment.
• Failure to comply may result in personal
injury and/or damage to equipment.

WARNING
Do not operate equipment
without reading and fully
understanding safety
warnings and instructions.
Failure to follow warnings and
instructions may result in serious injury.
NOTE
Do not operate equipment without
wearing personal protective gear.
Wear eye protection. Protective
equipment such as dust mask, non-skid
safety shoes, hard hat, or hearing
protection used for appropriate
conditions will reduce personal injuries.

Overview
Ultra high pressure pump tubes are
designed specifically for oil well services such
as wire line and plug valve applications. In
wire line applications, these pumps are used
to seal against the well head pressure as the
well is being logged or perforated. In plug
valve applications they are used to pump
heavy grease into the valve or “Christmas
tree valves” to seal any gas leaks.
These pump tubes are designed to be
used with Power-Master III air motors
(except  in (254 mm) size). They are
bushing and plunger style pump tubes with
shovel type foot valves. They are designed to
pump grease from a drum or bulk tank.
DANGER
Do not allow static sparking.
Static sparking can cause fire or explosion.
Pump, dispensing valve and containers must
be grounded when handling flammable fluids
such as petroleum products and wherever
discharge of static electricity is a hazard.
Failure to comply will result in death or
serious injury.

Air motor attachment
1 Refer to fig. 3. Tightly attach tie rods to air
motor (use short threaded end of tie rods).
2 Mount air motor on top of pump tube
outlet body and tightly connect coupling
nut (9) to air motor piston rod.
3 Hand tighten tie rods to pump tube with
four nuts supplied with air motor.
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 air
motor to pump tube.
Weep holes
Safety weep holes on the material outlet and
gauge ports allow for visual indication of
leakage and prevention of pressure build-up
in the threads. If leakage is detected, tighten
or replace fittings.
Maintenance and
repair
Relieve pressure from pump and supply lines
and remove or lockout air line to air motor
before servicing or repairing pump tube to
reduce risk of an injury from injection,
spraying fluid or moving parts.
For common issues and suggested
solutions, refer to Troubleshooting, pg. 14. Disassembly
Outlet housing
1 Refer to fig. 3. Unscrew bolt
connector (10) and coupling nut (9)
assembly from plunger rod (5).
2 Unscrew bushing nut (8) from
outlet body (11).
3 Remove v-packing set (7) from
bushing nut (8).
4 Remove six wave washers (6), two flat
washers (12) and o-ring (13) from
outlet body (11).
5 Remove adapter (14) from
outlet body (11).
NOTE
Pumps are factory tested with oil and a
portion is left in to protect pump parts during
storage and transportation. To prevent
contamination of material to be pumped,
flush pump before using.

NOTE
Pump tube disassembly should only be
performed at a service center by a qualified
technician.
Contact a Lincoln service center for more
information.

Priming tube removal
1 Refer to fig. 4.Insert pump tube into a
workbench mounted vise assembly able to
withstand torquing force exceeding
  ft.lbf (1 491 Nm).
2 Using a strap wrench, remove priming
tube (21) from priming tube adapter (22).
3 Remove cotter pin (19) from priming
plunger portion of priming check and
plunger (17) and priming plunger nut (20).
4 Unscrew priming plunger nut (20) from
plunger portion of priming check and
plunger (17).

Pump tube disassembly
In most cases, pump tube repair involves
priming check and plunger (17), bushing and
plunger (1) or plunger rod (5). Repair
procedure in part requires removing adapter
tube (23) and priming tube adapter (22)
from pump tube (25). In these cases, leave
pump tube (25) attached to outlet body (11).
1 Refer to fig. 5. Apply a torch to joint
between pump tube (25) and adapter
tube (23) and heat to approximately
 °F (177 °C).
2 Attach a torque multiplier wrench to
priming tube adapter (22) and loosen
adapter tube (23).
3 After allowing adapter tube (23) to cool,
attach a Parmalee-type strap wrench to
direct resisting torque into
bench top.
4 Heat joint between priming tube
adapter (22) and adapter tube (23) to
approximately  °F (177 °C).
5 With torque multiplier wrench, loosen
priming tube adapter (22) from adapter
tube (23).
Pump/adapter tube
disassembly
1 Remove check seat (18)and o-rings (30)
from adapter tube (23).
2 Remove bushing (1) and o-rings (29) from
pump tube (25)(† Fig. 5),
(†Fig. IPB1, pg. 13).
Fig. 5
NOTE
Pump tube consists of highly torqued tube
sections. Use a torque multiplier wrench (31),
a Parmelee-type strap wrench and a flame
torch to loosen and remove tube sections
from pump tube (25) († Fig. 5).
Free highly torqued parts by application of
the following where necessary:
• Heating joints of tube sections to
° F (117 °C) using flame torch. Monitor
temperature using an infrared laser heat
sensor.
• Torque multiplier wrench.
• Parmelee-type strap wrench attached in
an opposing direction to the torque
multiplier wrench.
NOTE
If torch is not available for heating tube joints,
use a small  lbs. (2.3 kg) sledge hammer to
loosen joints.
To do this, apply hammer blows around
the perimeter where the tube’s internal
threading is located.
This process allows the torque multiplier to
work at a lower force exertion.

Troubleshooting
Problem Possible cause Solution
Pump does not operate. Restricted or inadequate air supply. Check air supply pressure and air hose diameter (see air
motor manual for minimum air supply hose diameter).
Obstructed material output. Check output line for restrictions.
Erratic or accelerated operation. Pump is not primed. Prime pump.
Insufficient material supply. Refill material supply.
Pump operates on “down” stroke only
(missing “up” stroke)
Worn or damaged bushing and plunger (1)
or piston check (2, 4and 1).
Check and replace if needed.
Pump operates on “up” stroke only (missing
“down” stroke).
Worn or damaged priming check and
plunger (17) or check seat (18).
Check and replace if needed.
Insufficient material supply. Pump is not
intaking enough material to dispense on
both strokes.
Check inlet for restrictions. Lower output with material
valve.
Pump is operating but not dispensing
material.
Inlet check (17 and 18) is not seating or is
damaged.
Check and replace if needed.
