Memolub EPS Pillow Block

The MEMOLUB® EPS lubricator automatically delivers a small, precise amount of lubricant at regular intervals for an continuous supply of fresh lubricant directly to your lube point. Prevents over and under lubrication problems related to manual lubrication.

  • 120, 240 or 480cc lubricant capacity
  • 350psi max output pressure from start to finish
  • Use with Oil or Grease (up to NLGI #2)
  • Remote mount up to 40 feet from the lube point
  • Use in intermittently used applications

All MEMOLUB® EPS models use the same motor base assembly, making it easy to convert from one lubricant capacity to another by simply purchasing a low cost transparent housing kit.

Connecting Power to the EPS

The MEMOLUB® EPS is supplied with a 12" wire lead that is connected to an external power source. A constant 24VDC power is supplied during periods of machine operation and will continue to follow the program until power is removed. When initial power is supplied to the MEMOLUB® EPS lubricator it will cycle once and then follow the preset MEMO program. When power is turned off the lubrication cycle stops until power is reestablished.

Programming the MEMO System for use with the MEMOLUB® EPS

The MEMOLUB® EPS lubricant output is programmed using the simple MEMO system. It consists of a brass MEMO fitting, a black plastic timing-ring holder, and three plastic timing rings (one white, one red, and one black). The MEMO can be programmed to control both the frequency of lube cycles and the volume of lubricant discharged. Once the MEMO is programmed and installed any MEMOLUB® EPS lubricator will recognize the settings.

Basic Frequency Settings

There are 7 basic frequency settings that are suitable for most industrial applications.  They are programmed by installing one or a combination of the three colored timing rings into the ring holder attached to the brass fitting. When you screw the MEMOLUB® lubricator onto the brass fitting, the timing rings depress the switches on the bottom of the lubricator. This activates the lubricator program.

Note: The "Months to Empty" is based on continuous use of the MEMOLUB® EPS lubricator. The lubricant cartridge will last longer with intermittent use.

Adjusting the Volume of Lubricant

Included in the MEMO kit is eight spacer washers for adjusting the amount of lubricant discharged per lube cycle. Installing one, or a combination of all eight washers, into the brass MEMO fitting will limit the stroke length of the piston inside the lubricator.

  1. Lower temperatures can be achieved by using a low temperature grease and cold-weather battery packs
  2. Splitter Blocks cannot be used with oil, and are limited to 7 lubricant output settings.
  3. Maximum lube line length is dependent on ambient temperature, grease type and application back pressure.

Application Case Study
Case Study No. 403
Industrial Washer
An industrial washer in a truck engine plant has a pump and an orientation gear. The customer was using "gas generator" type lubricators to service the 3 pump bearings and orientation gear. Pump bearings were failing because the lubricant was getting clogged in the lines. The lubricators servicing the orientation gear were neglected because they were located inside the gear's protective cage, making them difficult to access. Months of no lubrication led to premature tooth wear.
All single-use lubricators were replaced with two 3-point lubrication systems. For the orientation gear, the lubrication system was remote-mounted outside the cage, for easy access. This not only made visual inspection of the lubs level easier, but also allowed for quick servicing of the lube system without the need for shutting down the washer.

Motors & Generators
Energy Industry
Our customer needed a solution to automatically lubricate the 250 hp electric motors located on the roof top.
Because these motors were in a very high location, the maintenance personnel had to climb several stories to manually lubricate the bearings.
Drive shaft bearing: Installed a single-point MEMOLUB® Mega lubricators filled with Mobil Polyrex EM grease with a change-out setting of 3 months. Support bearing: Installed a single-point MEMOLUB® HPS Standard filled Mobil Polyrex EM grease with a change-out setting of 3 months.
Streamlined their lubrication program and improved workplace safety.
Worth Mentioning:
Power Lube Industrial recommends the plastic Protective Cover for outdoor applications.
