READ THIS FIRST

Safety precautions

Read this instruction for use fully. Follow all safety

precautions to avoid personal injury or property

damage during equipment operation. SKF cannot

be responsible for damage or injury resulting from

unsafe product use, lack of maintenance or incorrect

equipment operation. In case of any uncertainties as

regards the use of the equipment contact SKF.

Failure to comply with the following could cause

equipment damage and personal injury.

• Do ensure that the equipment is only operated

by trained personnel.

• Do wear proper personal protective gear, such

as eye protection and protective gloves, when

operating the equipment.

• Do inspect the equipment and all accessories

carefully before use.

• Do not use damaged components or modify the

equipment.

• Do use clean recommended hydraulic oils

(SKF LHMF 300, LHDF 900 or similar).

• Do not use glycerin or water based ﬂuids as a

pressure medium. Premature equipment wear

or damage can result.

• Do not use the equipment above the stated

maximum hydraulic pressure.

• Do not adjust safety valves to work at pressures

above the maximum working pressure.

• Do not extend the handle in order to reduce the

required force to reach maximum pressure.

Use hand pressure only.

• Do not use the pumps with accessories, which

are rated below the maximum working pressure

of the pump.

• Do use a pressure gauge to monitor the oil

outlet pressure.

• Do ensure that all the air has been removed

from the hydraulic system before pressurising

the hydraulic system.

• Do prevent the workpiece (e.g. bearing,

gearwheel or similar item) from being forcibly

ejected upon sudden release of pressure

(e.g. by use of retaining nut).

• Do not use damaged hoses. Avoid sharp bends

and kinks when connecting hoses.

Sharp bends and kinks will internally damage

the hose leading to premature failure.

Applying pressure to a damaged hose may

cause it to rupture.

• Do not lift the equipment by the hoses or

couplings.

• Do follow local safety regulations.

• Do service the equipment by a qualiﬁed

hydraulic technician or SKF Repair Centre.

• Do replace worn or damaged parts with

genuine SKF parts.

1. Description

The 728619 E is a two stage pump. The pump

supplies a high rate of ﬂow (20 cm3per stroke)

below the switching pressure. Above the switching

pressure the ﬂow is automatically decreased to

1 cm3per stroke.

A 3 metre long high-pressure hose is supplied

to connect the pump to the workpiece. One end

of the hose has a quick-connection coupling for

the connection to the pump. The other end of the

hose has a G 1/4” quickconnection nipple for the

connection to the workpiece.

The pump comes preﬁlled with SKF mounting ﬂuid

(LHMF 300).

A 1 litre can of mounting ﬂuid is also included.

These items are stored in a sturdy metal box.

PRP

The pump has an oil outlet connection (P).

The pump also has a return connection (R), to

return oil to the oil container.

The return connection can be connected to an

external oil reservoir when the oil container capacity

is not sufﬁcient.

The release valve is in the pump head. The pump

includes a safety valve to prevent high pressure that

can cause damage to the pump.

3. Operating instructions

• Remove the container plug under the pump

handle to check the oil level.

Make sure there is sufﬁcient oil to complete the

operation. Use oil with a viscosity at operating

temperature of 300 mm2/s (1 400 SUS) to

mount bearings with the SKF Oil Injection

Method or a hydraulic nut. Use oil with a

viscosity at operating temperature of 900 mm2/s

(4 100 SUS) for dismounting bearings.

• Hold the pump in a horizontal position and

tilt forward as necessary to make sure the oil

supply is constant.

• Screw the quick connection nipple (G 1/4) tightly

into the workpiece. ABA

4. Maintenance

4.1 Filling the oil container

Set the pump on a ﬂat, level surface to ﬁll the oil

container. Remove the plug from the oil container.

Fill the oil container until the oil level is at the

bottom of the ﬁlling pipe. Do not ﬁll the pump above

the bottom of the ﬁlling pipe. Too much oil in the oil

container can cause a malfunction.

Make sure that there is no air in the oil system.

Check for air in the oil system after the oil is

replaced and after maintenance to the pump is

complete. Operate the pump, and make sure that

only air-free oil is supplied from the hose.

• Connect the hose to the quick connection nipple.

To connect or disconnect the hose you must

retract the collar on the quick connector. Do not

disconnect the hose while the oil is pressurised.

• Move the release valve to the pump position.

Do not tighten the valve too much. The release

valve is found on the side of the pump.

• Operate the pump until the pressure increases

to the level necessary for your application.

When the pressure is more than 150 MPa

(21 750 psi), the safety valve will open.

• Last, open the release valve to let the oil ﬂow

back to the oil container.

Use only clean hydraulic oils such as SKF LHMF 300

or LHDF 900.

4.2 Cleanliness

Do not let metal particles or other contamination

enter the pump or oil.

Contamination will decrease the service life of the

pump.
