Warning Read and follow the safety precautions and general instructions in this manual and
also in the SKF manual "Safety and general instructions for lubrication systems." Failure to follow
these instructions could result in serious injury or damage to the lubrication system or the equip-
ment that is lubricated.
2 General description
SKF-EPB-Pump-ECO is an electro-pneumatic barrel pump, in which the traditional mechanical valve control has been
replaced with an electronic control. The main purpose of the pump is to feed lubricant into a centralized lubrication
system. The pump can also be used as a separate transfer or filling pump. In such a case, it must be connected to a
separate 24 V power supply and a pressure air supply.
The pump is connected to a follower plate placed inside the lubricant barrel. This allows the pump to follow the lubri-
cant level. A complete pumping set consists of a pump, a lid set and a pressure air regulator. A separate installation kit
is required for installing the pump in an existing system. The installation kit contains components to adapt the existing
pneumatic and electrical connections to the EPB-pump.
Note! The SKF-EPB-Pump-ECO is intended for use with ECO lid sets, which are suitable for greases in NLGI
grades 1 and 2.

4 Operation
The pump is operational when the power supply is connected and the green LED-signal is lit. The pump's operation is
controlled by an internal circuit board. Signals sent by inductive sensors control the operation of the pneumatic valve.
The sensors identify the direction of movement of the air motor piston. The pump is equipped with an integrated low
level switch. The pump must be connected to a pressure air supply and a 24 VDC power supply. If the pump is used in
a centralized lubrication system, power is fed through the M12 connector, either from the internal control unit of the
hydraulic part or from an external control unit.
The pump can also be used as a separate transfer or filling pump. In such a case, it must be connected to a separate
24 V power supply through the M12 connector and to a pressure air supply. See section 7.2 Connections
(→page 15).

4.1 Start-up
4.1.1 Start-up – in a centralized lubrication system
Warning Electrical connections must only be made by qualified electricians. To minimize risk
of electric shock or electrocution, ensure that the pumping center is turned off before making any
connections. Operating voltage must be shut off before touching electrically conductive parts or
opening any parts of the system or component.
Warning Ensure that there is no pressure in the system. Before opening the grease filter,
remove pressure by opening the venting screw (15) in the filter plug. Turn off the pressure air sup-
ply by lifting up the shut-off valve button (17) or set the air pressure to 0 bar using the pressure
regulator (18) and the pressure gauge (19). Detach the M12 cable (12) from the pump. If the sys-
tem is under pressure when the components are being disconnected or opened, the components or
lubricant might be flung in the air causing injury to people or damage to the environment
Note! Ensure that the surroundings are clean. Make sure that no impurities enter the pump, the follower
plate or the barrel. Impurities may cause damage to the lubrication system or to the machine or device
it lubricates.
Note! The numbers in brackets indicate position numbers in Figures 1, 2 and 3 (→pages 2 and 3) .
1Check the condition of the lubricant barrel. Damage in the barrel will prevent the follower plate (9) from lowering.
2Remove the barrel's original lid and press the follower plate closely on top of the lubricant in the barrel. Ensure
that air is removed from below the follower plate and that the central unit of the follower plate is filled with lubri-
cant.
3Fasten the lid (8) onto the lubricant barrel with wing screws.
4Place the pump through the lid into the central unit of the follower plate. Ensure that the pump is firmly attached
to the follower plate.
5Connect the pump to a power supply through the M12 connector (6). See sections 7.2 Connections (→page 15)
and 7.3. Electrical connections to SKF pumping centers
(→page 17).If connected to other centers, confirm that
the connections comply with the center's electrical drawings.
6Connect the pressure air hose (11) to the pressure air regulator (18) and to the pump's inlet A.
7Using the pressure regulator (18) and the pressure gauge (19), set air pressure to 3.5–4.5 bar.
8Connect the tank hose (10) to the pump's pressure connection (P), and the other end of the hose to the grease
filter (14).
9Start the pump at the control or pumping center.
10 Remove air from the tank hose by opening the venting screw (15) of the grease filter.
11 Stop the pump at the control or pumping center.
12 Move the tank hose to the pump's tank connection (T), and the other end of the hose to the pumping center's tank
connection (T). Before attaching the hose, make sure that only grease is coming out of the hose (not air).

REPBECO1CEN.doc 07.03.2013 Rev. 1C 6 (30)
13 Connect the pressure hose (13) to the pump's pressure connection (P) and the other end of the hose to the grease
filter (14).
14 Start the pump at the control or pumping center.
15 Remove air from the pressure hose by opening the venting screw (15) of the grease filter.
16 Stop the pump at the control or pumping center.
17 Fill the header piping with lubricant by starting the pump at the control or pumping center.
18 Stop the pump when the header piping is filled and air is removed.
19 Check the header piping for leaks by pressurizing it. Make sure that the pressure is suitable for the system and for
the used piping material.
20 Using the pressure regulator (18) and the pressure gauge (19), set the air pressure of the pumping center to
3.5–4.5 bar. At this pressure, the pump feeds lubricant through its pressure connection P at a pressure of 220–
290 bar (3200–4200 psi / 22–29 MPa).
4.1.2 Start-up – as a transfer or filling pump
Warning Electrical connections must only be made by qualified electricians. Operating volt-
age must be shut off before touching electrically conductive parts or opening any parts of the sys-
tem or component.
Warning Ensure that there is no pressure in the system. Before opening the grease filter,
remove pressure by opening the venting screw (15) in the filter plug. Turn off the pressure air sup-
ply by lifting up the shut-off valve button (17) or set the air pressure to 0 bar using the pressure
regulator (18) and the pressure gauge (19). Detach the M12 cable (12) from the pump. If the sys-
tem is under pressure when the components are being disconnected or opened, the components or
lubricant might be flung in the air causing injury to people or damage to the environment
Note! The tank connection (T) and the tank hose (10) are not normally used when the pump is used as a
transfer or filling pump. A separate power supply is required (24 VDC / min 0.2 A, e.g. SKF code
12381505).
Note! Ensure that the surroundings are clean. Make sure that no impurities enter the pump, the follower
plate or the barrel. Impurities may cause damage to the lubrication system or to the machine or device
it lubricates.
Note! The numbers in brackets indicate position numbers in Figures 1, 2 and 3 (→pages 2 and 3) .
1Check the condition of the lubricant barrel. Damage in the barrel will prevent the follower plate (9) from lowering.
2Remove the barrel's original lid and press the follower plate closely on top of the lubricant in the barrel. Ensure
that air is removed from below the follower plate and that the central unit of the follower plate is filled with lubri-
cant.
3Fasten the lid (8) onto the lubricant barrel with wing screws.

REPBECO1CEN.doc 07.03.2013 Rev. 1C 7 (30)
4Place the pump through the lid into the central unit of the follower plate. Ensure that the pump is firmly attached
to the follower plate.
5Connect the pump to a power supply through the M12 connector (6). See section 7.2 Connections (→page 15).
6Connect the pressure air hose (11) to the pressure regulator (18) and to the pump's inlet A.
7Using the pressure regulator (18) and the pressure gauge (19), set air pressure to 3.5–4.5 bar.
8Connect the pressure hose (13) to the pump's pressure connection (P) and the other end of the hose to the grease
filter (14).
9Start the pump by turning on the power.
10 Remove air from the pressure hose by opening the venting screw (15) of the grease filter.
11 Stop the pump by turning off the power.

6 Troubleshooting
6.1 LED-signals for self-diagnostics
Self-diagnostics is an automatic function. During the first working stroke, the system checks that the piston works cor-
rectly:
•Both inductive sensors confirm movement within 5 seconds →green LED-signal is lit
•Only one of the sensors sends a confirmation →yellow LED-signal is lit. Replace the inductive sensors.
•Neither of the inductive sensors sends a confirmation →red LED-signal starts blinking. First, check the pressure
of the pressure air supply. If the fault is not cleared, replace the inductive sensors.
