MEMOLUB HPS Installation Instructions

General
The MEMOLUB® HPS (High Pressure System) is both an
advanced design, highly accurate, single point automatic
lubricator and a low cost miniature central lubricating system.
It operates as a battery powered self-contained lubricator.
Models are also available that use an external 4.5, 12 or 24DC
volt power source. MEMOLUB® can operate under its own
program control, under control of the machine being
lubricated or a PLC.
The MEMOLUB® Multi-Point System can be used to lubricate
between 2 and 12 lubrication points. Using pipe or tubing, the
MEMOLUB® HPS can be mounted remote from the bearing
being lubricated (see page 4 for details). This feature is
valuable when it is necessary to lubricate hard to reach
bearings, to avoid extremely high temperatures, harsh or
hazardous environments or when mounting the MEMOLUB®
HPS away from excessive vibration.
When operating as a self-contained lubricator the MEMO
programming system controls the frequency of lubricant
ejection cycles. The MEMO also controls the volume of
lubricant ejected on each output cycle when the MEMOLUB®
is operating as either a self contained lubricator or under
external control.
Installation
On first installation, use a hand grease gun and the same type
of lubricant to pre-charge all fittings, lines, the bearings. The
MEMOLUB® HPS positive displacement pump has been
primed before shipment and is ready for use. If, however, the
pump becomes unprimed due to running the lubricator
without an empty lubricant cartridge, or operating the
lubricator without a cartridge in place, it should be primed

before installing the new lubricant cartridge. This step does
not need to be repeated when changing the MEMOLUB® HPS
lubricant cartridge. To prime the pump, using a hand grease
gun, pump grease through the upper valve of the MEMOLUB®
HPS until grease comes out of the bottom outlet. Two pumps
of grease is generally sufficient. The "Check Function" (page
2) can be used to insure that the pump is primed.
The MEMO has a ¼" NPT thread. It can be adapted to other
thread sizes using standard adapters.
adapters are listed on the Installation Parts and Accessories
sheet.
Batteries
MEMOLUB® HPS will operate successfully at temperatures up
to 120°F (49°C). Areas of high temperatures can often be
serviced by remote mounting the MEMOLUB® HPS using
pipe or tubing. If constant low temperatures (i.e. -4°F (-20°C)
or lower) are encountered, low temperature approved greases
and MEMOLUB Cold Weather Battery Packs should be used.
The Cold Weather Battery Pack should always be used when
using the MEMOLUB® HPS Giga (Model 480) at temperatures
lower than 32°F (0°C).
The test function should be used on a regular basis when
working under extreme temperature conditions. The shelf life
of a battery pack stored at 68°F is 2 years. Only MEMOLUB®
battery packs should be used in the MEMOLUB® HPS
lubricator.
External Power Source
MEMOLUB® lubricators using an external power source are
described in detail on separate product sheets.
How MEMOLUB® HPS Works
MEMOLUB® HPS is a fully self-contained electro-
mechanical lubricator utilizing a patented positive
displacement pump.
The main components are a motor, gearbox, piston
pump, microprocessor. A cam fitted to the outlet
gear drives a lever which lifts the hollow piston and
simultaneously compresses a spring.
piston reaches the top of its stroke, the lever is freed
from the cam and the piston begins its downward
(working) stroke, driven by the spring. Lubricant is
drawn into the chamber formed above the piston
during its downward ejection stroke preparing it for
the next cycle.
