LINCOLN FlowMaster II Rotary Driven Electric Pump Instruction Manual

Safety

Read 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.

Always disconnect power source (electricity, air or hydraulic) from equipment, if applicable, when it is not being used.

Adequate personal protection must be used to prevent material from contacting the skin or eyes.

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.

• Port shut-off body: 1/2 NPTF

Overview

Model 85859 is a FlowMaster II rotary driven pumping unit designed to operatea Centro-Matic lubrication system.

The pump includes motor speed control and built in circuit protection to prevent control burnout. The pump is double acting, dispensing lubricant on both “up” and “down” strokes. The model 85859 also includes:

• A 2 in. (50,8 mm) follower plate.
• An electric loat switch.
• A vent valve for relieving line pressure to recharge the injectors.
• A mechanical shut-off valve.

This unit is for use with SL-V, SL-1, SL-11, SL-32 and SL-33 series injectors.

Mechanical shut-off valve

The mechanical shut-off valve automatically shuts off the illing of the reservoir withoutpower applied to the system.
As grease lows through the valve and into the reservoir, the follower raises until it contacts the pivot arm. The pivot arm then raises until it contacts the pin on the shut-off valve and closes the valve. When the valve closes, the low of the grease to the reservoir stops.
Shut off the ill pump and relieve pressure between the ill pump and the shut- off valve in order to disconnect the ill line safely.
Keep the pressure relief valve activated until the supply line pressure on the gauge falls below 200 psi (13 bar). The ill line can then be removed at the quick disconnect point.

Installing the pump

Locate unit so that electric power connection is 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 reservoir to the equipment.
3. Connect lubricant outlet of pump to system with suitable hose capable of 3 500 psi (241 bar) working pressure.

Bare pump assembly

Refer to 85738 operation manual 404517 for setting pump speed on 24 V DC motor.

Filling reservoir

To bulk ill reservoir, attach the supply line to port “P” on shut off valve. Refer to igure 3, page 5 and verify system is connected and start ill pump.

When reservoir is full, shut-off valve will close. Grease in ill line will be under high pressure. Relieve grease pressure before disconnecting ill hose by opening pressure relief valve.

WARNING
Do not over-ill reservoir. Extreme pressure can damage reservoir.
Failure to comply can cause death and/or serious personal injury

Refer to Filling reservoir with optional 278552 bypass manifold assembly, page 5.

Maintenance and repair

General maintenance

• Keep area around pump and illing port clean, as lubricants attract dirt and debris.
• Keep lubricants free of contaminants.

WARNING
Do not perform maintenance or service on assembly with any power source connected.
Failure to comply can cause death and/or serious personal injury.

System malfunction

Refer to Troubleshooting, page 6 for determining common problems and solutions.

Outlet check service

Refer to ig. 1. The pump will not build up suficient lubricant pressure if the outlet check assembly (5) is fouled. Foreign material may lodge beneath the steel ball (47) or between check bushing assembly (44) and the seat of pump check disc assembly (43). Sealing surfaces of seat must fully seal.

1. Remove hose assembly (11).

2. Remove entire outlet check bushing (5), street elbow (6) and adapter (4).

3. Remove elbow (6) and adapter (4) from outlet check bushing (5).

4. Remove outlet connector (48) from check bushing assembly (44).

5. Remove pump check disc assembly (43) from outlet connector (48).

6. Inspect all check components (43, 44, 45, 47) for presence of foreign material, scoring and or other damage, that may cause internal leakage. Replace components if damage is found.

7. Replace gaskets (29) and (46) whenever outlet pump check disc assembly (43) is disassembled.

8. For assembly, torque outlet connector (48) and check bushing assembly (44) to 100 ft-lbf (13.5 Nm).

Safety unloader valve

Refer to ig. IPB1, page 7. If pressure switch fails to operate, safety unloader (15) activates at 3 750 to 4 250 psi (259 to 293 bar) lubricant pressure to relieve supply line pressure. Safety unloader (15) is not serviceable and must be replaced if malfunctioning occurs

WARNING
Do not operate without safety unloader installed.
If not installed, install safety unloader before using pump.
Failure to comply may result in death or serious personal injury.

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

Upon reassembly, tighten to 10 ft. lbf. (13.5 Nm). Safety unloader is preset and non-adjustable.

Follower

Refer to († ig. 2) and († ig. IPB 1, page 7). Service unit if follower foam is damaged or fails to wipe sides of reservoir effectively.

1. Remove bolts (17) and lock washers (18) attaching the cover to the reservoir.
2. Lift the entire pump, vent valve and cover assembly out of the reservoir.
3. Remove the entire follower assembly from the reservoir (37).
4. Loosen and remove nuts (56) and weighted follower plate (57) on top of the follower.
5. Remove and replace follower foam (55).
   NOTE
   For assembly, install long bolts staggered with short bolts as shown.

Filling reservoir with optional 278552 bypass manifold assembly

1. Lock out and tag out electrical systems.
2. Relieve pressure from system until gauge is at “0”.
3. Connect pump to quick connect itting.
4. Turn ill pump on until guage reaches maximum and ill pump stalls.
5. Shut off the ill pump.
6.  Activate pressure relief valve.
7. Reduce pressure until the control manifold gauge is under 200 psi (13,8 bar).
8. Disconnect quick connect itting.

DANGER
Do not allow pressure to exceed 6 000 psi (413,6 bar).
Do not operate pump without pressure regulator or pressure relief valve to regulate maximum pressure delivered by pump.
Pressure regulator or relief valve not provided.
Failure to comply may result in serious injury or death.

NOTE
For ease of illing tank, pressure relief valve or pressure regulator (not provided) can be mounted remotely.
Refer to Fig. 3 for proper connection of hoses.

NOTE
Do not ill reservoir until grease level drops at least 1 in (25 mm).
