Operation of the Magnetic Pump
• The magnetic pump should only be used if it is in good
technical condition.
• Defects and faults which may impair its operation and
safety must be remedied immediately.
• The reservoir must be refilled in due time with clean oil.
• Should you need more information than is given in this
User Manual, please contact our company (see address
below).
• The PMA-2 magnetic pump is exclusively designed for
use in centralized oil lubrication systems.
• The limiting values specified in the Technical Data,
particularly in the maximum operating pressure and the
maximum frequency, must on no account be exceeded.
• Any other use is not in accordance with the specified
instructions.
• The manufacturer is not liable for damages resulting
from improper use.
Maintenance and Repairs
• Before any maintenance or repair on the magnetic pump
is done, the User Manual and the Safety Instructions
must be read.
• The User Manual must be available on the site where the
pump is in operation.
• Alteration or modifications of the magnetic pump are only
allowed if approved by the manufacturer.
• For repairs use only original Lincoln spare parts.
• If other spare parts are used, the manufacturer may be
released from its liability for the resulting consequences.

Fig. 1 - Magnetic pump for chain lubrication via spray nozzle
• The magnetic pump is designed to be used as an oil
supply pump, preferably in chain lubrication systems.
• It can be used in a centralized lubrication system either
- as a splash lubrication device for the accurate lubricati-
on of chain studs and rollers, if used in connection with
nozzles,
or
- as a drop lubrication or brush lubrication device, if used
with progressive divider valves.
• Due to the high pulse frequency the pump is also suita-
ble for high-speed chains.
• the pump is driven by an electromagnet (2, fig. 2).
• The movement of the drive pinion (teeth or chain) is
sensored by the proximity switch (7, fig. 1) which, in this
way, controls the electromagnet for splash lubrication.

Start-up
Connection of the tube lines and filling of the pump
* connect the pressure line(s) and the filling line to the
corresponding connections on the pump.
Take care that no dirt or other foreign
particles enter the pump housing.
* Clean the tube lines before connecting them.
* Avoid contamination of the environment.
* Fill the reservoir with clean oil.
* Open the shut-off valve in the oil supply line to the pump.
Venting
* Unscrew the venting screw (E, Fig. 11) until oil emerges.
Then re-tighten the venting screw.
* Let the pump run until all connected nozzles operate
properly.
Operation
• The armature of the electric solenoid (2, Fig. 2) receives
an electrical pulse (energizing) from the proximity switch
(6, Fig. 1). It contacts the piston support (4, Fig. 2) via a
tappet (3). The piston support causes the pistons (6) to
move.
ErectionandInstallation
• even, solid and vibration-free installation surface
• protected from dust and dirt
• safe from atmospheric influences
• Installation position: horizontal, venting screw
to the left or to the right
• Oil supply: free oil supply from the
reservoir
Tightening torque of the faste-
ning screws 15 Nm 10%
Max. length of tube line
to the nozzles:
Output 60 mm³: steel tube 6 m
plastic tube 3 m
Output 30 mm³: steel tube 3 m
plastic tube 1.5 m
Specifications of the installation site Electrical connection
Before connecting the device,
disconnect the system from the
power supply.
The installation and connection of electric devices must
be carried out only by qualified electrician personnel!
Observe the relevant rules of technology and the respec-
tive work protection legislation (directives, standards).
Electric connection of the electrical solenoid
• in accordance with the electrical wiring diagram and the
switching diagram
Electric connection of the proximity switch
• in accordance with the electrical wiring diagram and the
switching diagram
OperatingInstructions
Maintenance and Repair
Before undertaking any repair on the
pump:
*Disconnect the system from the
power supply and make sure that it
cannot be restarted inadvertently
* Close the shut-off valve in the oil
supply line
* Reduce the pump and system
pressure to zero. Danger due to
splashing oil.
•Repair work may be carried out only by qualified
personnel using original Lincoln spare parts.
• Provided that the pump dispenses only clean oil, it does
not need any particular maintenance.
• The piston of each pump element lies directly in the oil
being dispensed and is therefore lubricated automatical-
ly.
• The pistons eject a dosed quantity of oil to the pressure
connection (P). The return stroke of the pump pistons
and that of the armature are spring activated. During the
return stroke the pistons suck fresh oil from the storage
chamber. The pump is ready for the next lubrication
pulse.
• A proximity switch (optional version) monitors the operati-
on of the pump.

• Fault: Pump does not supply
• Cause: • Remedy:
• Electric solenoid defective * Check the supply voltage, replace the defective
electrical solenoid.
• Fault: Pump does not supply, solenoid receives pulses
• Cause: • Abhilfe:
• No oil in the system * Check the oil supply to the pump. Refill the reservoir.
• Piston damaged * Replace complete pump element
• Suction borehole clogged * Remove pump element, clean it and check for foreign
particles
• Air in the system * Vent the pump and the tube lines (see „Start-up“)
•Any repairs which are beyond the knowledge of the user’s personnel must be carried out by Lincoln experts. For this
purpose, return the defective pup to the repair department of the Walldorf works or call for a specialist who will carry out
the repair on site.

Troubleshooting
NOTE: The following items only describe faults occuring at the pump itself. Faults due to an electric failure or system mal-
function must be looked up in the system description.
• After any replacement or repair the tube lines and the
pump must be vented again.
• The pistons are subject to natural wear, which depends
on the cycle time and pressure setting.
