Grounding

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

FIG. 3.

Mounting

Install the pump in a location that will adequately sup-

port 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).

Low Level

For models equipped with a low level switch, connection

is made to pins 1 and 2 for normally closed operation or

pins 1 and 3 for normally open operation. See FIG. 4.

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 break-

down.

FIG. 3

Mount the pump securely so that it cannot move

around during operation. Failure to do so could result

in injury or equipment damage.

FIG. 4

Installation

Air and Fluid Line Accessories

Refer to FIG. 1 and FIG. 2, pages 5 and 6, for the follow-

ing instructions.

Install the air line accessories in the order shown in FIG.

1 and FIG. 2, pages 5 and 6.

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).

a. Install a t-fitting (P) at the pump inlet.

b. Install a hose between the t-fitting and vent

valve.

-Electric Vent Valve

Connect to pump air control valve power.

a. Install a DIN connector into the vent valve.

b. Connect the leads to the controller output that

signals the pump to turn on.

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 pressur-

ized.

Grease Models 17T193 and 17T194; Oil

Models 17T195 and 17T196

1. Stop pump. Relieve pressure. See Pressure Relief

Procedure, page 11.

2. Disconnect air line from pump.

3. Remove plug (57) from pump base (2) (FIG. 5).

4. Install valve cartridge (68) in pump base (FIG. 5).

Torque coil nut (a) to 4 to 5 ft-lbs (5.42 to 6.78 N•m).

Torque cartridge nut (b) to 16 to 20 ft-lbs (21.69 to

27.12 N•m).

Trapped air can cause the pump to cycle unexpect-

edly, which could result in serious injury from splash-

ing 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.

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 com-

ponents connected to a particular pump.

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 (FIG. 6).

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.

2. Slowly add oil (ol) until reservoir is filled to capacity

(FIG. 7). Take care to not fill reservoir too quickly and

overflow the reservoir capacity.

3. Close oil fill cap (32) to prevent contamination and

spillage (FIG. 7).

Grease Models

1. Remove dust cap (42) (FIG. 8) from fill stud (26).

2. Connect the quick connect fitting on the fill pump to

the fill stud (26) on the reservoir.

3. Slowly dispense grease from the fill pump into the

reservoir until the grease in the reservoir lifts the fol-

lower plate (45) above the reservoir vent hole (vh)

and air is expended from under the follower plate

(FIG. 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 reser-

voir 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 FIG. 9.

The approximate location of the vent hole is identified as

vh in the illustration.

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

8).

5. Secure dust cap (42) over fill stud (26) (FIG. 8).

Priming

Refer to FIG. 1 and FIG. 2, pages 5 and 6, for the follow-

ing instructions.

NOTE:

• Prime the pump before connecting the outlet to sup-

ply 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.

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 injec-

tor stem should move when lubricant is discharged.

2. Adjust the injector output if needed to ensure that

the output volume discharged is sufficient.

Over-pressurization can result in equipment rupture

and serious injury. Fill slowly to avoid over pressuriz-

ing reservoir.
