Mounting
Install the pump in a location that will adequately sup-
port the weight of pump when filled with lubricant and
also provides easy operator access to the pump air con-
trols. Pump must be mounted in a vertical position with
the reservoir up.
See Technical Data, page 31 for pump weight informa-
tion and the Dimensions and Mounting layout, page 30.
Grounding
To ground the pump: Remove the ground screw (GS)
located on the back of the pump base and insert it
through the eye of the ring terminal (RT) at end of
ground wire (GW). Fasten the ground screw (GS) back
onto the pump and tighten securely. Connect the other
end of the ground wire to a true earth ground. See FIG.
2.
Mount pump securely so it cannot move around
during operation. Failure to do so could result in per-
sonal injury and/or equipment damage.
Grounding is necessary when voltages above 30
VAC or 42 VDC are used for the low level switch or
for an air valve attached to the pump. Improper
grounding can cause electric shock. Grounding
reduces the risk of electric shock by providing an
escape wire for the electric current in the event of
malfunction or breakdown.

Trapped air can cause the pump to cycle unexpect-
edly, which could result in serious injury from splash-
ing or moving parts.

Installation
3A3169E 7
1. Install a bleed-type master air valve (F) to relieve
air trapped between it and the pump. Install the
valve in a location that is easily accessible from the
pump and located downstream of the air regulator.
2. Install an air line filter (B1) to remove harmful dirt
and contaminants from the compressed air supply
3. Install the air regulator (B2) to control pressure.
4. Install an air line lubricator (B3) to lubricate the air
cylinder.
5. Install the (4-way) air solenoid valve (C) for control
of the pump forward and return strokes.
To use the air regulator reading to determine the fluid
output pressure, multiply the ratio of the pump (19:1) by
the air pressure shown on the regulator gauge or see
Table 1: Lubricant Output - PSI or Table 2: Lubricant
Output - MPa (bar), provided on page 12.
Limit the air to the pump so that no air line or fluid line
component or accessory is over pressurized.
Air Supply Lines (UU)
1. Install two air supply lines (UU) between the air
solenoid valve outlets (C) and the pump (D) as
shown in the Typical Installation, page 4.
2. Install an air supply line (UU) between the air sole-
noid valve inlet (C) and the Filter/Regulator/Lubrica-
tor Assembly (B) as shown in the Typical
Installation, page 4.
Oil Input Supply System
The oil input supply pump/system (DD) must have a
pressure reducing valve (U).
Oil Input Lines
Shut-off Valve (V): Allows isolation of the LubePro
pump from the incoming oil supply line (CC).
Required on the oil input supply pump/system (DD).
Hoses: Use a minimum 3/8 inch supply line (S).
Pressure Reducing Valve (U): circulates excess oil
pressure back to the tank. Install this valve (U) in the
supply line with a drain hose (EE). Limit supply pres-
sure to a maximum 80 psi (0.55 MPa, 5.5 bar)).
Fluid-filled Pressure Gauge (Y): monitors hydraulic
pressure to the LubePro Single Stroke Pump during
startup.
NOTICE
Do not mount the air accessories directly on the sole-
noid valve air inlet. The air inlet and fittings are not
strong enough to support the accessories and may
break. Provide a bracket on which to mount the
accessories.
The maximum working pressure of each component
in the system may not be the same. To reduce the
risk of over-pressurizing any part of your system,
know the maximum working pressure rating of each
component and its connected components. Never
exceed the maximum working pressure of the lowest
rated components connected to a particular pump.
To reduce the risk of over-pressurizing the LubePro
Single Stroke Pump which could cause a rupture and
serious injury, including fluid injection, an oil input
supply system must have a means to limit the incom-
ing fluid pressure to the LubePro Single Stroke Pump
to a maximum of 80 psi (0.55 MPa, 5.5 bar).

Installation
83A3169E
Starting Pump
1. Make sure the supply line (G) is connected and
there are no open lines for oil to leak out of the
pump outlet (E).
2. Close the oil supply shut-off valve (V).
3. Turn on the oil input supply pump/system (DD).
4. Adjust pressure reducing valve (U) to limit the oil
inlet pressure to 80 psi (0.55 MPa, 5.5 bar).
5. Slowly open the oil supply shut-off valve (V).
6. Remove the trapped air in the pump reservoir (K) by
slowly opening the cock valve (BB) until oil can be
seen coming out after all the air is released as
shown in FIG. 6.
7. Close the cock valve (BB).
Supply Lines
1. If there are multiple pumps on the air line, close the
air regulators (B2) and bleed-type master air
valves (F) to all but one the pumps. If there is only
one pump, open its air regulator and bleed-type
master air valve.
2. Open the master air valve (F).
3. Set the air pressure to each pump at the lowest
pressure needed to get the desired results. See
Recommended Pressure provided in Table 1:
Lubricant Output and Pressure - US or Table 2:
Lubricant Output and Pressure - Metric provided
on page 12.
4. Remove trapped air in the supply line (G) by
removing a plug or opening a fitting on the furthest
end of the supply line. Run the pump until oil comes
out. After oil free of air comes out, close the line.
Feeder Lines (S)
Fill each feeder line (S) with lubricant prior to connect-
ing lines to the injector outlet.
Injectors (H)
For the following instructions, refer to Typical Installa-
tions, FIG. 1, page 4, for the following instructions.
1. Check each injector (H) for proper operation. The
injector stem should move when lubricant is dis-
charged.

Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
1. Close the bleed-type master air valve (F) (required
in the system).
2. Close the shut-off valve (V) on the oil input sup-
ply pump/system (DD).
3. Relieve pressure in system using two wrenches
working in opposite directions on the pump outlet
(E) and lubrication line fitting (G) to slowly
loosen the fitting until it is loose and no more lubri-
cant or air is leaking out of the fitting (FIG. 7).
Air Lock Procedure
An air lock occurs when a bubble or pocket of air pre-
vents the normal flow of the lubricant.
If there is an air lock, first:
• Check that input supply oil line (CC) is connected
and that the oil flow is continuous to reservoir (K).
• Loosen the cock valve (BB) from the pump reser-
voir cover (L) to bleed out the air.
If the air lock persists:
1. Relieve pressure. See Pressure Relief Procedure,
page 9.
2. Disconnect the lubricant supply line (G) from the
pump outlet (E) (FIG. 8).
3. Open the bleed-type master air valve (F, page 4).
4. Open the shut-off valve (V).
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as skin injection, splashing
fluid and moving parts, follow the Pressure Relief
Procedure when you stop dispensing and before
cleaning, checking, or servicing the equipment.
FIG. 7

5. Run the pump a few strokes until oil (ol), free of air,
comes out of the pump outlet (E) (FIG. 8).
• It may take up to 20 the pump strokes to expel the
air from the pump and deliver a continuous flow of
oil. This will depend on the viscosity of the lubricant
and temperature.
• Allow a minimum of 5 seconds ON time for the for-
ward stroke and 5 seconds OFF time for the return
stroke.
6. Connect the pump outlet (E) to the lubrication line
(G) (FIG. 9).
Operation
Start Up
1. Verify reservoir is filled with lubricant and system
has been Primed (see Prime System, page 8).
2. Turn on the lubrication controller (J) power switch.
3. Program the lubrication controller to actuate the
solenoid valve (C).
NOTE: See the lubrication controller instruction
manual included with the system for these instruc-
tions.
4. Open air regulators and master air valves.
NOTE: Never allow the pump to run dry of the material
being the pumped.
At the start of a the pump cycle:
a. The air solenoid (C) supplies air to the pump
air inlet (P).
b. On the pump forward stroke, lubricant is dis-
pensed to all the injectors.
c. The pump is supplied with air through the air
inlet (R).
d. The pump makes a return stroke, venting the
system pressure back to the pump and resetting
all of the injector.
FIG. 9

NOTICE
Running the pump dry will cause an air lock. To prevent
an air lock, do not run the pump without lubricant.
Always refill the pump before it is empty.

Operation
3A3169E 11
Low Level Switch
When the oil reservoir is full, the low level float (llf) sits in
the high, raised position as shown in FIG. 10.
As oil is dispensed, the low level float begins to travel
down. When the oil in the reservoir reaches low level,
the fully traveled down float (shown in FIG. 11) closes
the normally open low level switch and a low level signal
is sent to the lubricator controller (J).
To clear the low level fault/error:
• Check that input supply oil line (CC) is connected
and that the oil flow is continuous to reservoir (K).
• Loosen the cock valve (BB) from the pump reser-
voir cover (L) to bleed out the air.
Shut Down
To shut down the system:
a. Close the bleed-type master air valve (F).
b. Turn off electrical supply to the lubrication con-
troller (J).
c. Close the shut-off valve (V) on the oil input
supply pump/system (DD).
