The difference between Electrochemical & Electromechanical Lubricators

Electrochemical Lubricators

An “Electrochemical” single-use automatic lubricator dispenses lubricant at a controlled rate by activating an internal gas generator.  The gas is generated by combining two elements in a sealed chamber.  As the amount of gas increases it builds up pressure against the piston which dispenses the lubricant into your lube point.  Once the eletrochemical lubricator has expelled all the lubricant it is disposed of and replaced with a new lubricator.  Because the electrochemical lubricators utilizes a chemical reaction to generate the gas, it is sensitive to high and low temperatures, meaning the gas generation decreases in lower temperatures and increases in higher temperatures.   This product can be used on most plant-wide production equipment and is usually safe for hazardous locations.

Electromechanical Lubricators

An "Electromechanical" lubricator dispenses lubricant by means of a mechanically driven piston or an internal positive displacement pump.  The lubricator is usually battery powered (external power models available) which operates a small motor that cycles or advances the piston to eject lubricant to your bearing.  This pump design can dispense grease at higher output pressures and is not affected by fluctuating temperatures.
