MEMOLUB HPS - No Lubricant Output; Cartridge Not Emptying Correctly

MEMOLUB

HPS User’s Guide Page 19 of 39 PLI, LLC
 Is there a plastic ring inside the ring-holder? If not, no switch will be activated and
the MEMOLUB
®
HPS will not work.
8.2 No lubricant is coming out of the MEMOLUB
®
HPS
If the MEMOLUB
®
HPS does function, and no grease comes out of the unit when doing a
manual test, consider the following:
 Is there a lubricant cartridge installed? If not, recharge the unit with a cartridge as
described in Section 6.3.
 Were the spring and compression plate inserted correctly inside the transparent
housing dome? (See Section 6.3)
 Is the pump of the MEMOLUB
®
HPS primed? If the MEMOLUB
®
HPS cartridge
was completely emptied before replacement, some air could have been sucked into
the system and the pump would be pumping air for a certain number of cycles.
Place a hand grease gun on the inlet of the red housing and pump grease through
the unit (See Section 6.3). If a grease gun is not available, prime the pump by
manually cycling the MEMOLUB
®
approximately 10 times while the new
cartridge is in place (see Section 6.5).
8.3 The lubricant cartridge does not empty correctly
If the MEMOLUB
®
HPS functions and lubricant is ejected, however, the lubricant
cartridge does not empty or not in the predicted timing, check the following:
 Is the tubing clogged? Use a hand grease gun to clear tubing.
 Is one of the outlets of the distributor block obstructed? Use a hand grease gun and
maintenance adapter (available through PLI) to flush the distribution block until
grease runs freely from all ports in equal amounts.
 Is tubing damaged? Replace tubing.
 Is counter-pressure higher than 290psi? Only use tubing with ¼” (6mm) inner
diameter or more, fittings with 1/8” NPT threads or higher, and a maximum 12-
point distribution block. When counter-pressure is between 290psi and 350psi, the
MEMOLUB
®
HPS will empty at a slower pace.
 At working temperature, the base-oil viscosity of the grease is higher than what’s
described in 5.2 Table of pipe and tubing lengths. Use a grease appropriate for
your application.
 The constant temperature where the MEMOLUB
®
HPS is used is too cold for the
standard alkaline battery pack. Use cold weather (Lithium) battery packs in
extreme cold situations (refer to section 1.4.2: Battery Packs).
