peration 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.
 f you need more information than is given in this Owner
Manual, please contact our company (see address
below).
 The PMA-1 magnetic pump is exclusively designed for
use in centralized oil lubrication systems.
 The limiting values specified in the Technical Data,
particularly 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 Owner Manual and the Safety nstructions
must be read.
 The Owner 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 spare parts.
 f other spare parts are used, the manufacturer may be
released from its liability for the resulting consequences.

Fields of Application
4112a97
Fig. 1 - Magnetic pump for chain lubrication via spray nozzles
 The magnetic pump is designed to be used as an oil
supply pump, preferably in chain lubrication systems.
 t can be used in a centralised lubrication system either
- as a splash lubrication device for the accurate lubrication
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 frequency of 3 / s the pump is also
suitable for high-speed chains.
 The pump is driven by an electromagnet.
 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.
CAUTI N 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. 2), until oil emerges.
Then re-tighten the venting screw.
* Let the pump run, until the oil flows out of all outlets
without air bubbles.
* Connect and vent tube lines.
Operation
 The armature of the electromagnet (2, Fig. 2) receives an
electrical pulse (energizing) from the proximity switch (7
Fig. 1; ). t contacts the pressure plate (4, Fig. 2) via a
tappet (3). The pressure plate causes the movement of
the pistons in the pump elements (5)to move.
Erection and Installation
 even, solid and vibration - free installation surface
 protected from dust and dirt
 safe from atmospheric influences
 nstallation position: horizontal, venting screw
upward
 Oil supply: free oil supply from the
reservoir
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 personnel!
bserve the relevant rules of technology and the respec-
tive protection legislation (instructions, 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.
Operating Instructions
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 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
which is dispensed and is therefore lubricated automati-
cally.
 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.
 The movement of the magnet and thus the operation of
the pump are monitored via the proximity switch (6, fig.2
optional version).

 Fault: Pump does not supply
 Cause:  Remedy:
 Electromagnet defective * Check the supply voltage, replace the defective
electromagnet.
 Fault: Pump does not supply, magnet receives pulses
 Cause:  Remedy:
 No oil in the system * Check the oil supply to the pump. Refill the reservoir.
Check the filter.
 Pump element damaged or defective * Replace pump element
 Suction borehole of the pump element is 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)
 All the repairs which are beyond the knowledge of the users personnel must be carried out by L NCOLN experts. For
this, return the defective pump 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 occurring at the pump itself. Faults due to an electric failure or system
malfunction are mentioned in the system description.
 The pump elements are screwed in on the outside and
can, therefore, be replaced without difficulty. When
replacing pump elements, observe the instructions given
above.
 After any replacement or repair the pump must be vented.
 The pump element is subject to natural wear and tear
which depends on the cycle time and pressure setting.
