Grounding

Grounding is required if a low level switch and/or an
air valve using voltages above 30 VAC or 42 VDC
are 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.

Secure ground wire to grounding screw (66) as shown in
F

IG. 3.

Mounting

Mount the pump securely so that it cannot move
around during operation. Failure to do so could result
in injury or equipment damage.

Install the pump in a location that will adequately sup­port the weight of the pump when filled with lubricant
and also provides easy operator access to the pump air
controls. See Technical Data, page 35 for pump weight
information and the Dimensions and Mounting layout,
page 28.

1. Secure wall bracket (39) to mounting location. (User
must provide mounting hardware.)

2. Install pump bracket (38) to wall bracket (39).
Secure pump bracket to wall bracket using washers
(60) and nuts (44).

Install the air line accessories in the order shown in F
1 and F

IG. 2, pages 5 and 6.

IG.

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 the 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.

Trapped air can cause the pump to cycle unexpect­edly, which could result in serious injury from splash­ing or moving parts. An air shut off valve (bleed-type
master air valve) is required for the system to protect
you from injury when you are adjusting or repairing
the pump. The air bleed device relieves air trapped
between it and pump after the air supply is shut off.

1. Install an air line filter (B1) to remove harmful dirt
and contaminants from the compressed air supply

2. Install the air regulator (B2) to control pressure.

3. Install an air line lubricator (B3) to lubricate the air
cylinder.

4. 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 and located
downstream of the air regulator.

5. Install the(3-way) air solenoid valve (C) for control of
the pump strokes.

6. Connect the vent valve (M).

- Pneumatic Vent Valve

Connect the air powered vent valve to the pump
supply air (A1).

7. To use the air regulator reading to determine the
fluid output pressure, multiply the ratio of the pump
(40:1) by the air pressure shown on the regulator
gauge; i.e., 40 psi x 40 = 1600 psi (2.75 bar x 40 =
110 bar; 0.27 MPa, x 40 = 10.8 MPa).

8. Limit the air pressure to the pump so that no air line
or fluid line component or accessory is over pressur­ized.

Fill Reservoir

Oil Models

1. Open oil fill cap (32) on the top of the reservoir.

NOTE: A filter (33) is installed at the oil fill cap (32) to
prevent lubricant contamination (F

a. Inspect filter (33) before filling reservoir.

b. When needed, remove filter (33) and clean it

thoroughly.

c. If removed in Step b, install filter (33) prior to

adding lubricant.

Over-pressurization can result in equipment rupture
and serious injury. Fill slowly to avoid over pressuriz­ing reservoir.

3. Slowly dispense grease from the fill pump into the
reservoir until the grease in the reservoir lifts the fol­lower plate (45) above the reservoir vent hole (vh)
and air is expended from under the follower plate
(F

IG. 9). A small amount of grease may come out of

the vent hole at this time.

Care must be taken not to overfill the reservoir. An
over filled reservoir will vent the excess grease out
of the vent hole (vh) until enough grease is expelled
for the follower plate (45) to block the vent hole.
Overfilling the reservoir could also cause the reser­voir to rupture due to over-pressurization.

NOTE: The vent hole (vh) is located toward the back
right side of the reservoir and cannot be seen in F

The approximate location of the vent hole is identified as

vh in the illustration.

IG. 9.

Priming

Refer to FIG. 1 and FIG. 2, pages 5 and 6, for the follow­ing instructions.

NOTE:

• Prime the pump before connecting the outlet to sup­ply line (G).

• Before priming the pump, the reservoir must be filled
with lubricant (see Fill Reservoir instructions, page

8).

Run the pump until lubricant, free of air, comes out of
the pump outlet (E). It may take up to 20 pump strokes
to expel the air from the pump and deliver a continuous
flow of lubricant. This will depend on the viscosity of the
lubricant and temperature.

Supply Lines

1. Run the pump until the oil (ol), free of air, comes out
of the pump outlet (E). Connect the supply line (G)
to the pump outlet (E).

2. If there are multiple pumps on the air line, close the
air regulators and bleed-type master air valves to all
but one of the pumps. If there is only one pump,
open its air regulator and bleed-type master air
valve.

FIG. 9

4. Disconnect the fill pump from the fill stud (26, F

8).

5. Secure dust cap (42) over fill stud (26) (F

IG. 8).

3. Open the master air valve from the compressor.

4. Set the air pressure to each pump at the lowest
pressure needed to get the desired results.

Feeder Lines

Fill each feeder line with lubricant prior to connecting
feeder lines to the injector outlet or divider valve.

Injectors

1. Check each injector for proper operation. The injec­tor stem should move when lubricant is discharged.

2. Adjust the injector output if needed to ensure that
the output volume discharged is sufficient.

Divider Valves

1. Check for valve operation by

- using a performance indicator (shows that the
valve has cycled),

- or, checking for lubricant dispensing at each
lube point.

2. Adjust the injector output if needed to ensure that
the output volume discharged is sufficient.

Pressure Relief Valve
Adjustment

The pressure relief valve is factory set to 4000 psi
(275.8 bar, 27.6 MPa) for grease models and 1000 psi
(68.95 bar, 6.89 MPa) for oil models.

The relief point may require adjustment in systems that
have components that are rated higher or lower than the
factory presets. Do not exceed 4000 psi (275.8 bar,

27.6 MPa) in either grease or oil systems.

Pressure Relief Procedure

Follow the Pressure Relief Procedure whenever
you see this symbol.

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.

1. Close the bleed-type master air valve (F, page 5)
(required in the system).

2. To relieve pressure in the system use a wrench to
slowly loosen the lubrication line fitting (G) until no
lubricant or air is leaking out of the fitting (F

IG. 10).

To adjust the pressure relief
valve, turn the pressure
adjustment screw (a) clock­wise to increase the pres­sure relief point or
counter-clockwise to
decrease the pressure relief
point.

Whenever the valve is
set/adjusted (after the set
point is found) it is important
to ensure that the valve is not bottomed out and there is
at least 1/2 turn of adjustment remaining. This is deter­mined by turning the screw (a) 1/2 turn and then back
turning it out again.

Operation

Refer to FIG. 1 and FIG. 2, pages 5 and 6, for the follow­ing instructions.

Pump

Start Up

1. Verify reservoir is filled with lubricant and system
has been Primed (see Prime System, page 10).

2. Turn on the lubrication controller (J) power switch.

3. Program the lubrication controller to actuate the air
solenoid valve (C).

NOTE: See the lubrication controller instruction
manual included with the system for these instruc­tions.

4. Open air regulators and master air valves.

NOTE: Never allow the pump to run dry of the material
being the pumped.

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 reservoir before it is empty.

Low Level Switch

(Models 17P751 (grease) and 17P753 (oil) only)

Oil Model 17P753

When the oil reservoir is full, the low level float (37) sits
in the high, raised position as shown in F

FIG. 11: Low level float in raised position

As oil is dispensed, the low level float (37) begins to
travel downward. When the oil in the reservoir reaches a
low level, the magnet in the bottom of the float activates
the low level switch (35), changing its state to either
open or closed.

Grease Model 17P751

As the grease is dispensed, the follower plate (45) trav­els down the reservoir. When it gets close to the low
level switch (35), the magnet on the bottom of the fol­lower plate assembly activates the switch, changing its
state to either open or closed.

IG. 11.

At the start of a the pump cycle:

a. The pump is supplied with air through the air

solenoid valve (C) and then to the pump air inlet
(R).

b. Fluid is pumped to the lube metering device

until the air solenoid valve (C) is turned off.

c. After the air solenoid valve (C) shuts off, the

pneumatic vent valve relieves the pressure in
the lubricant lines (A1 and A2).

d. In systems using a vent valve, fluid pressure is

vented to the pump reservoir.

In systems using an electric vent valve, an elec­trical signal to the vent valve is required to build
pressure. The same signal can be used to cycle
the air valve and close the vent valve.
