What are the advantages of a Dual-Line parallel Automated Lubrication System?

Groeneveld Twin Dual Line Parallel Automatic Lubrication SystemA Duel-Line Parallel (also called a 'Twin Line' parallel or 'Two-Line' parallel) Automated Lubrication System is your go-to ALS when you're faced with long pumping distances, as well as extreme temperatures.

How does the Dual-Line Parallel Automatic Lubrication System work?

The dual-line parallel ALS provides high pressure —up to 5,000 PSI for those who're wondering! One of the biggest assets of the two-line parallel is that it is specifically designed to work with numerous lubrication points over wide areas.

The system's pump provides high pressure to its metering device through one side of a reversing value that features a four-way, duel positioned reversing valve and the first supply line. The control piston of the meter takes on the job of shifting and directing lubricant to the main piston, which in turn, sends the specified amount of lubricant to the bearing.

On the other side of the control piston, lubricant is vented back to the lubrication reservoir via the second supply line (hence, 'dual-line') and the opposite side of the reversing valve. Finally, the reversing valve will shift so that the pump will then pressurize supply line number 2 and ultimate repeat the cycle, this time in reverse.

What are the advantages of a Twin-Line parallel Automated Lubrication System?

  • Heavy greases are a non-issue —the dual-line parallel ALS handles it easily.
  • Accommodates long pumping distances when when a long supply line runs between the pump and meter.
  • Designed to work with many lubrication points spread over a wide area.
  • Easily adjustable to meet specific bearing requirements.

What are the disadvantages of a Dual-Line parallel Automated Lubrication System?

  • Not always the most cost effective option when working with smaller systems.
  • Because it is a two-line supply system, you have the added cost of having a second line.
