Explanation of safety signals

Indicates a hazardous situation which,

if not avoided, could result in minor or

moderate injury.

Indicates a hazardous situation which,

if not avoided will result in death or

serious injury.

Indicates a hazardous situation which,

if not avoided, will result in death or

serious injury.

This is the safety alert symbol. It is used

to alert you to potential physical injury

hazards. Obey all safety messages that

follow this symbol to avoid possible

injury or death.

SafetyRead and carefully observe these installation

instructions before installing, operating or

troubleshooting the referenced equipment.

Referenced equipment must be installed,

maintained and repaired exclusively by

persons familiar with the instructions.

Adequate personal protection must be

used to prevent splashing of material on the

skin or in the eyes.

Always disconnect power source

(electricity, air or hydraulic) from equipment,

if applicable, when it is not being used.

If any luid appears to penetrate the skin,

seek medical treatment immediately. Do not

treat injury as a simple cut. Tell attending

physician exactly what luid was injected.

Failure to comply may result in personal

injury and/or damage to equipment.

Any other use not in accordance with

instructions will result in loss of claim for

warranty or liability.

• Never exceed maximum speciication

ratings of the equipment.

• Do not misuse, modify parts, or use worn

and/or damaged parts.

• Always read and follow the manufacturer’s

recommendations regarding the use of

protective clothing and equipment.

OverviewModel 85875 is a pumping unit designed to

operate a Centro-Matic lubrication system.

The unit includes a vent valve to relieve line

pressure to recharge injectors.

FlowMasterII rotary driven hydraulic

pump includes pressure reducing valve, low

control valve and solenoid operated

(24 V DC) “on/off” valve. The pump is double

acting, dispensing lubricant on both “up” and

“down” strokes.

The unit is for use with SL-V, SL-1, SL-11,

SL-32 and SL-33 series injectors.

System Operation

When all bearings have received lubricant,

pressure rises in the system, activating the

pressure switch. When pressure switch

activates, the control is reset to de-energize

the solenoid valve cutting off hydraulic oil

pressure to the pump and vent valve.

Pump stops, pressure vents and pressure

switch deactivates. Control begins timing

toward next lube event.

Installation

Locate unit so that electric and hydraulic

power connections are accessible.

1 Mark center locations of the six holes at

the bottom of the reservoir.

2 Drill six 1/2 in. (13 mm) holes. Use 7/16 in.

(11 mm) bolts for added lexibility in

securing the reservoir to the equipment.

3 Connect lubricant outlet of pump to sys-

tem with suitable hose capable of

3,500 psi (241 bar) working pressure.

Connect hydraulic inlet with at least 3/8 in.

(9 mm) I. D. hose capable of at least3,000 psi

(207 bar) operating pressure. Connect

hydraulic return to tank connection line with 3/4 in. (19 mm) I. D. hose or pipe.

Bare pump assembly

Refer to 85877 operation manual 404693

for setting pump speed on 24 V DC motor.

Filling reservoir

To bulk ill the reservoir, attach model 80933

button head coupler to the button head con-

nector (75) on the lower ill port. Fill reser-

voir until the grease level gauge indicates it is

full or until grease appears at the top high

level port. Remove the button-head coupler.

� WARNING

Do not overpressurize reservoir during illing

process.

Failure to comply can cause damage

to reservoir, death and/or serious per-

sonal injury.

assembly (44) and the seat of pump check

disc assembly (43). Sealing surfaces of seat

must fully seal.

1 Remove hose assembly (15).

2 Remove entire outlet check assembly (13),

street elbow (12) and adapter (14).

3 Remove street elbow (12) and adapter

(14) from outlet check assembly (13).

4 Remove outlet connector (48) from

check bushing assembly (44).

5 Remove ball check (45) from outlet

connector (48).

6 Inspect all check components (43, 44, 45,

47) for presence of foreign material,

scoring and or other damage, which may

cause internal leakage. Replace compo-

nents if damage is found.

7 Replace gaskets (42) and (46) whenever

outlet check assembly (13) is

disassembled.

8 For assembly, torque outlet connector (48)

and check bushing assembly (44) to

100 ft.lbf (13.5 Nm).

Maintenance and repair

General maintenance

• Keep area around pump and illing port

clean, especially prior to illing reservoir,

as lubricants attract dirt and debris.

• Keep lubricants free of contaminants.

� WARNING

Before performing maintenance or ser-

vice, disconnect all hydraulic and electric

power to the pump assembly.

Failure to comply can cause death

and/or serious personal injury.

In case of system malfunction

Refer to Troubleshooting (pg. 5) for deter-

mining common problems and solutions.

Outlet check service

Refer to Fig. 1 and Fig. IPB1, pg. 6. The

pump will not build up suficient lubricant

pressure if the outlet check assembly (13) is

fouled. Foreign material may lodge beneath

the steel ball (47) or between check bushing

Safety unloader valve

Refer to Fig. IPB1, pg. 6. If pressure

switch fails to operate, safety unloader (1)

activates at 3,750 to 4,250 psi (259 to

293 bar) lubricant pressure to relieve supply

line pressure. Safety unloader (1) is not ser-

viceable and must be replaced if malfunc-

tioning occurs.

Upon reassembly, tighten to 10 ft. lbf.

(13.5 Nm). Safety unloader is preset and

non-adjustable.

Vent valve service

1 Refer to fig. 2 and fig. IPB1, pg. 6.

Loosen hose assembly (15) and (vent)

hose assembly (11).

2 Remove hex head cap screws (40) and lock

washers (39) and remove vent valve (26).

3 Position vent valve (26) in vice with vice

jaws gripping lats on vent valve base.

4 Remove elbows (25, 27) and reducer

nipple (16).

5 Remove cylinder (51) with piston and

u-cup assembly (50).

Low level indicator

Refer to Fig. 3 and Fig. IPB1, pg. 6. If indi-

cator pin appears to drop prematurely or

water is noticeable on top of follower indica-

tor, seal may be damaged.

1 Remove bolts (4, 18) and washers (19)

holding the cover on the reservoir.

2 Inspect the reservoir gasket (21) for

damage and replace if necessary.

3 Remove the entire pump, vent valve and

follower assembly from the reservoir.

4 Remove the retaining ring (57) from the

cable assembly (58).

5 Hold the indicator plug (62) with a wrench

while removing the indicator nut (60).

6 Remove and replace the O-ring (59).

7 For assembly, torque the indicator nut

(60) to 20 ft-Ibs.

6 Remove packing assembly(49) from

cylinder (51).

7 Inspect needle (52 and valve seat (53) for

foreign matter that may be lodged and

keeping needle (52) from sealing in valve

seat (53).

8 Clean and inspect again for damage.

Replace if valve seat (53) appears dama-

ged by nicks, grooves or scouring.

9 Remove valve seat (53) from valve body

(54) by placing a 3/4 in. open end wrench

onto the lats. Using an adjustable wrench,

turn open end wrench to loosen seat.

10 Replace valve seat (53) if damaged.

11 Remove and replace the check seat

gasket (55) below the valve seat (53).

12 To ease assembly, coat needle (51) and

cylinder (50) inside diameter with

lubricant.

13 Install valve seat (53) into valve body (54)

to a torque of 25 ft.lbf. (39 Nm).

14 Install cylinder (50) onto valve body (53)

and tighten to a torque of 100 ft.lbf.

(135 Nm).

� WARNING

Do not plug outlet of safety unloader.

Plugging safety unloader outlet will

result in pressure build up.

Failure to comply may result in death

or serious personal injury.

� WARNING

Safety unloader ships with the pump

assembly, but is not pre-installed.

Safety unloader must be installed

before using pump. Do not operate

without safety unloader.
