15
Lubricants
6.1 General information
Different lubricants are used in different applications. In order to fulfil their tasks, lubricants must fulfil various
requirements to varying extents. The most important requirements for lubricants are:
•reduction of abrasion and wear
•corrosion protection
•noise minimisation
•protection against contamination and entry of foreign objects
•cooling (primarily for oils)
•longevity (physical/chemical stability)
•compatibility with as wide range of materials as possible
•economic and ecological aspects
6.2 Lubricant selection
SKF considers lubricants to be an element of system design. A suitable lubricant is selected already when
designing the machine and it forms the basis for centralised lubrication system planning.
The selection is made by the manufacturer/end-user of the machine, preferably together with the lubricant
supplier based on a defined requirement profile.
Should you have little or no experience with the selection of lubricants for centralised lubrication systems,
please contact SKF.
If required, we will be glad to support customers in selecting suitable components for feeding the selected
lubricant and planning and designing their centralised lubrication system.
You will avoid possible costly downtimes caused by damage to your machine/system or the centralised
lubrication system.
Only lubricants specified for the product may be used. Unsuitable
lubricants may lead to product failure.
Do not mix lubricants. This may have unforeseeable effects on the
usability and therefore on the function of the centralised lubrication
system.
Due to the multitude of possible additives, it is possible that individual
lubricants, which according to the manufacturer's data sheets match the
system’s specification, might not in fact suitable for use in centralised
lubrication systems (e.g. incompatibility between synthetic lubricants and
materials). To avoid this problem, always use lubricants tested by SKF.

16
6.3 Material compatibility
Lubricants must generally be compatible with the following materials:
•steel, grey iron, brass,
•copper, aluminium
•NBR, FPM, ABS, PA, PU
6.4 Ageing of lubricants
After a prolonged downtime of the machine, the lubricant may no longer be suitable for use due to chemical or
physical ageing and must therefore be inspected before the system is recommissioned. We recommend
inspecting the lubricant already after a week’s downtime.
If you suspect that the lubricant is no longer suitable, replace it prior to recommissioning and, if necessary,
perform initial lubrication manually.
It is possible for lubricants to be tested in the company's laboratory for their suitability for being pumped in
centralised lubrication systems (e.g. no "bleeding").
Please contact SKF if you have further questions regarding lubricants.
An overview of the lubricants tested by SKF is also available upon request.

17
MPB pump general description
The purpose of the pump is to supply lubricant to a centralised lubrication system. The pump is suitable for
greases up to grade 000-2 (NLGI), and it has both an outlet connection (pressure connection, “P”) and a
return connection (tank connection, “T”). Its pressure ratio is 65:1, which means that the pump's maximum
allowable lubricant pressure (≈300 bar, 30 MPa) is achieved at 4.5 bar air pressure. The minimum air
pressure required for operation is 2 bar (0.2 MPa).
SKF-MPB-PUMP is composed of an air motor and a pump unit. The air motor is controlled by a pneumatic
valve, which in turn is controlled by a mechanical valve controller. The mechanical valve controller follows the
motion of the air motor’s air piston. A connecting rod transmits the motion of the air piston to the pump unit's
piston assembly, which pressurises the lubricant. The air motor has been designed to be lubrication-free,
which means that no lubricator is needed in the air filter regulator assembly.
The pump is intended for central lubrication systems consisting of a pump and lid set, air filter regulator and
lubrication system control unit (each sold separately). Installing the MPB pump in an existing system driven by
an SKF-EPB pump requires an additional installation kit, which includes the components required for
connecting the pump in the lubrication system.
ATTENTION
The pump is intended for intermittent use only. If the pump is used continuously at high
pressure, or moist pressurised air is used, the pneumatic valve may freeze, causing a
malfunction.

18
Commissioning
The pump is activated when air (minimum pressure: 2 bar) is supplied to its pressurised air inlet (4). The pump
pressurises the lubricant, transferring it through the lubricant outlet (5) into the lubrication system. The pump
also includes a tank connection (6). During depressurisation, lubricant returns through the tank connection into
the pump pipe and, from there, back to the lubricant barrel. Lubricant pressure can be adjusted from the
pressure air regulator (sold separately). When used in a central lubrication system, the pump's air supply is
controlled by a control centre (sold separately) following user-defined lubrication values.
The pump can be equipped with a low lubricant level alarm (sold separately), which is connected to the
lubrication system’s control centre.

Periodic inspections
Monthly inspections
•Inspect the pressure air regulator and drain it of water.
•Check the pump’s operation.
•Check the pump and lubrication system for leaks.
When replacing the barrel (in addition to the above):
•Clean the grease filter and the filter cartridge and replace them if necessary.
Troubleshooting
WARNING
Before addressing the following malfunctions, turn off the power from the control and
pumping centre, isolate the pressurised air supply and depressurise the lubrication line
connected to the pump outlet. Any residual pressure in the system when opening or
disconnecting components may cause components to be thrown or lubricant to spray,
causing injury to people or damage to the environment.
11.1 Malfunctions
In case of a malfunction:
– Check the air pressure and the condition of the air lines.
– Check that the grease filter and the hydraulic lines connected to the pump outlet are not clogged.
– If the problem persists, contact your Oy SKF Ab representative.
