Introduction
Refillable autonomous and programmable lubricant dispenser for one or multiple lubrication points
Lubrication is an important part of maintenance. The lubricant dispenser, the lubrication point, the quantity, and
the frequency are the primary elements of effective lubrication, and therefore also of optimal productivity. In
modern factories, the lubrication points are greased by means of centralized systems. These are very efficient
when they are well maintained, regulated and controlled. The remainder is mainly lubricated manually or with
small independent lubricators at low pressure.
MEMOLUB PLCD (PLC) is a powerful (25 bar) and precise electro-mechanical lubricant dispenser with the
purpose of centralizing and automating the lubrication. It functions independently, contains
an oil or grease bellow, and is driven by the PLC control system. A progressive distributor can be used
to lubricate several points simultaneously. It can also (if feasible) be mounted directly at the lubrication
point, or convey the lubricant through lines to the lubrication point.

by inserting up to
Finer programing setting by means of black dosage washers
If a more precise feed rate setting should be necessary, this can be accomplished by inserting up to
five small black dosage washers and a steel clamp ring into the cylinder of the MEMO.

Warranty
A warranty is provided for the mechanical and electronic components for 12 months following the invoice date,
under the condition that the controller's casing has not been opened and the transparent flange is not damaged.
The warranty is limited to the replacement of the lubricator. The inspection of the proper function of the device
lies in the responsibility of the user.
Further information concerning the MEMOLUB can be found at the Internet site www.memolub.com.

Installation regulations for the lubricator 24 V DC-PLC
1. Program the lubrication
amount by inserting the
dosage washers.
General instructions
2. Mount the MEMO directly
on the lubrication point or
the progressive distributor.
3. Screw the
MEMOLUB® onto the
MEMO.
4. Connect the MEMOLUB® 24
V DC-PLCD (PLC) to a PLC.
The PLC regulates the
frequency of the lubrication
cycles.
(PLC is not included)
Maintenance
Operation with an empty cartridge should be avoided. To make the pump suck again, use a grease gun
without grease nipple. One or two strokes are enough.
Stop / Start
Five seconds after being screwed into the lubrication point, the lubricator starts the first lubrication cycle. The
MEMOLUB can be switched off and on (machine standstill, weekends, vacation closedown, etc.) at any time.
The MEMOLUB is simply screwed out and back in by three rotations for this. After being screwed in, the
MEMOLUB runs a self-test and is immediately operational.
Caution! In progressive distributors and/or long lines filled full with lubricant, decompression can occur in these
systems. The MEMO is then filled with lubricant. When screwing the MEMOLUB onto the MEMO, pressures of
up to more than 100 bar can occur, and this may damage the MEMOLUB. Use a "SAFETY-MEMO" for
progressive distributors and/or long lines.
Line lengths for central lubrication
The lengths of the lines depend on the type of grease to be conveyed and the ambient temperature. With
multi-purpose grease and temperatures of over 100 °C, the following line lengths are used. At 4 mm inner
diameter: max. 6 m for single lubrication point, max. 8 x 2.5 m for progressive distributors.
