Operation of Magnetic pump
 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 Instructions
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.
 If other spare parts are used, the manufacturer may be
released from its liability for the resulting consequences.
Appropiate Use
Safety Instructions
 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.
 If you need more information than is given in this Users
Manual, please contact our company (see address below).

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.
 It can be used in a centralised 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 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.
CAUTION 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 (item 4, 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.
Operation
 The armature of the electromagnet (2, Fig. 2) receives an
electrical pulse (energizing) from the proximity switch (7
Fig. 1; ). It 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.
 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 cham-
ber. 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,optio-
nal version).
Erection and Installation
Specifications of the installation site
 even, solid and vibration - free installation surface
 protected from dust and dirt
 safe from atmospheric influences
Installation position:...........horizontal, venting screw upward
Oil supply.............................free oil supply from the reservoir
Max. tube length
to the nozzles.....................6 m
Electric Connection
The installation and connection of electric devices
should be carried out only by qualified personnel!
Observe the relevant rules of technology and the re-
spective industrial protection legislation (instructions,
standards).
Electric connection of the electromagnet
 In accordance with the electric wiring diagram
Electric connection of the proximity switch
 In accordance with the electric wiring diagram
Befor connecting the device, discon-
nect the system from the power
supply.
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 inadvertent-
ly
* 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.
 It is subject to natural wear and tear which depends on the
cycle time and pressure setting.

Troubleshooting
NOTE: The following items only describe faults occurring at the pump itself. Faults due to an electric failure or system mal-
function are mentioned in the system description.
 The pump elements are screwed in on the outside and,
therefore, they can be replaced without difficulty.
 When replacing pump elements, observe the instructions
given above.
 After any replacement or repair the pump must be vented.
