The high pressures, high speeds, close mechanical tolerances and high operating temperatures of hydraulic equipment mean that oil cleanliness is crucial to the life expectancy of these systems. Yet, while hydraulic-systems engineers now include oil-cleanliness levels in their specifications, only a few manufacturers will install the hardware needed to meet these targets. It generally falls to the end-user or the maintenance contractor to retrofit hydraulic reservoirs with kidney-loop filtration on site.
True kidney-loop filtration functions independently of the designed lubrication system of the machine. Like on-demand oil dialysis, it remains the best form of healthcare for extending the service life of lubricated equipment. Also called off-line filtration, it can be added to most equipment in the field. The fundamentals are simple:
Things have changed.
To add kidney-loop filtration to most lubricated equipment—and quickly begin capturing the benefits it can provide—you’ll need:
OILMISER™ Technology offers a family of tools and accessories to help you do it. Delivering all three prerequisites in a single, easy-to-install component, the OILMISER Off-Line Filtration Kit allows you to replace the original filler/breather on the reservoir without shutting down the hydraulic system. For example, the tank-mounted model shown above can add independent kidney-loop filtration to most hydraulic reservoirs in just minutes. Without any tank modifications, the six screws and the existing filler breather are removed, exposing the 2”-diameter opening. Incorporating the same six-hole footprint, the filtration kit can be almost effortlessly inserted into the reservoir and screwed into place. (A 2” NPT male pipe-mounted version of the kit is also available.)
OILMISER Off-Line Filtration Kits are shipped fully assembled and ready for immediate installation. All of these products can be ordered with the following options: an external oil sampling port with an internal sampling tube; a variety of top-end couplers to accommodate alternative air filters, including desiccant air breathers; and quick disconnects with dust covers.

Gravity lubricators have been a mainstay in industry for decades. The idea is simple: Keep lubricant flowing to gears, chains, bearings and friction points to avoid premature wear and failure. The results can be astounding in terms of machine performance, avoidance of downtime and cost savings. So what’s left
Lubrication technology that goes beyond simple needle-valve controls to deliver a precise amount of fluid is available—now! Does it merit the investment in time and money? Ask yourself these 10 questions:
Answering “yes” to any one of these questions could be reason enough to retool your lubrication program. It still can be a risky move, however, to trade an economical and simple gravity oiler for a “lubrication system” with extensive controls and high-pressure connections.
The simple and cost-effective way to take advantage of technology is to opt for a positive displacement pump, such as PurgeX® by Oil-Rite. This 4” pump is powered by bursts of compressed air. Each cycle dispenses a small, precise amount of fluid. Its operation does not vary with environmental conditions, and it can even pull fluid from a reservoir without the assistance of gravity. A timer (or PLC) and 3-way solenoid are the only controls needed. Typical 120-psi shop air is converted to as much as 1080 psi at the outlet—yet the unit can be installed with flexible tubing and nylon barbed fittings.
The precision and reliability of PurgeX eliminates many of the pitfalls of gravity lubrication. It is not complex to understand or install, and is versatile enough to suit a wide range of applications.
UltraLube® is a complete line of professional-grade greases, oils and spray lubricants and penetrants specifically formulated and packaged for a variety of agricultural, commercial, industrial, manufacturing, marine and transportation uses.
With four times the natural lubricity of petroleum-based oils, UltraLube products instantly penetrate into areas where lubrication is needed most, creating a long-lasting bond to metal and plastic surfaces. Made from crops grown in the U.S., UltraLube has a vegetable-based formula that is eco-safe and non-toxic, making it safer for use in work environments.
UltraLube greases and oils are ideal for environmentally sensitive areas, since they are VOC-free and non-flammable with extremely high flash points.
UltraLube supplies superior lubrication for hundreds of industrial purposes including ball-and-socket joints, bearings, cables, conveyors, cutting tools, drive chains, electric power tools, gears, glides, hinges, hydraulic components, linkages, precision tools, pumps, rollers, valves and many other applications. UltraLube products are also effective rust inhibitors.
Certified by the USDA’s BioPreferred program, UltraLube products can help federal agencies and contractors meet green procurement mandates that require purchases of biobased products within identified categories, such as hydraulic fluids and lubricants. The range of UltraLube products made specifically for heavy-duty applications includes:
