An automatic lubrication system is one that provides your equipment with the right amount of lubricant at the right time and in the right place – usually while the machine is in operation. It replaces a conventional lubrication system such as a grease gun.
Why is it necessary?
“The effects of under-lubrication are well-known: increased component wear, premature failure, higher energy usage, increased operating and maintenance costs,” says Charles Hartl, Global Product Marketing Manager Lubrication Equipment Division at Graco. “But the effects of over-lubrication can be just as harmful. It wastes lubricant, can lead to excess heat build-up, puts stress on lube points, and increases downtime. The solution is obvious: optimal lubrication.”
And that’s exactly where automatic lubrication comes in, because by providing smaller amounts of lubricant at more frequent intervals, you avoid both over- and under-lubrication. Automatic lubrication results in extended equipment life, reduced wear and smaller maintenance bills.
What do you need?
The main components for automatic lubrication are:
"Graco provides a wide portfolio of complete automatic lubrication solutions that contain all the components necessary,” adds Hartl. “Based on pneumatic, hydraulic or electric drives, they are suitable for all types of mobile or industrial application, and we can even tailor a solution for a specific application.”
Following is a brief overview of some of Graco’s leading automatic lubrication solutions.
Electric grease pumps
The super-efficient design of Graco’s electric grease pumps delivers the right amount of grease at the right time – all in a neat, compact system. An example is the Electric Dynastar. Ideal for mining operations, heavy-duty construction, industrial applications, and milling & crushing, the high pressure model is capable of 5,000 psi (344 bar) with a maximum output of 18 cubic inches (295 cc) per minute. This model maintains its high
performance levels even in temperatures as low as -40C. If the application demands high flow, there is an Electric Dynastar model capable of providing 3,500 psi (241 bar) with a maximum output as high as 25 cubic inches (410 cc) per minute.
At the heart of the product is the Graco Advantage Drive™. It consists of high quality, hardened steel helical gears lubricated for life and sealed to keep contaminants out for longer lasting performance. It’s been field-proven for over ten years to be the longest lasting drive in the industry.
What’s your conventional picture of greasing a vehicle such as a truck or tractor? Crawling under the frame and lying on your back to grease the tie rods and lower kingpins? Painfully stretching to reach the spring hangers hidden behind the fuel tank?
With the Graco EZ Greaser these discomforts belong to the past. This single point lube system consists of lubrication lines connected directly to the lube point. Once installed, it just takes a few pumps of the grease gun and your entire chassis is lubricated and ready for the road.
What was a complicated, time-consuming job is now as easy as point and squeeze. And because it is so easy, chances are it will be done when scheduled, leading to less wear and tear from improperly lubricated fittings. As it’s a contained system, sand and dirt are prevented from entering the lines, eliminating a source of wear.
Pneumatic oil and grease pumps
Graco has been making pneumatic oil & grease pumps for over seven decades; ever since the company launched the high-pressure Fire-Ball® lubrication pump in the mid-1950s. Their latest product is the LubePro™ series of pumps, which leverages the proven quality and leading technology of the Fire-Ball®.
These pumps offer a robust solution where high output and fast lubrication cycles and flow rates are needed to optimally lubricate equipment while it’s working. Available for grease or oil, the LubePro™ covers a wide variety of in-plant manufacturing applications. Features include the integrated self-venting pump, which automatically relieves pressure on the return stroke without the need for a pressure switch or wiring, and an optional low level indicator.
The LubePro™ H1900 pump pushes productivity a notch higher. It enables plant maintenance staff to fill it remotely. It is designed to attach to an oil header line from a remote fill station. This eliminates the need to individually fill pump oil reservoirs around the plant.
Electric oil and grease pumps
In the crowded marketplace of electric oil & grease pumps, the G3™ Electric Lubrication Pump stands out. Designed for longer lasting performance and reliability, G3 meets fluctuating temperatures, challenging installation requirements and changing grease types head-on. Specially contoured base funnels grease directly to the pump inlet to significantly reduce stagnant flow areas where soaps and grease fillers can accumulate.
The G3 is the ultimate in flexibility so is at home in multiple markets and applications. It works with both injector-based and series progressive systems. The UV-resistant, high-impact reservoir is available in multiple sizes (2, 4, 8, 12 or 16 liters) for oil and grease to meet the needs of your equipment. You can mix and match up to three cycle or pressure switches for custom installations and feedback. It is delivered with one adjustable pump element – but has room for two more for higher output on large projects. And it has three controller options – Standard, Pro and Max – so you buy only what you need for your application.
Oil and grease dividers
Graco makes a wide range of top quality progressive dividers. They meet the lubrication requirements of bearings and other lubrication points, and are available in carbon steel and stainless steel.
The Trabon MSP Series was the original modular-style series progressive divider valve – and continues to be highly rated. Its quick change valve sections can be removed from the base assembly without disturbing any lube
lines. This minimizes labor cost and maximizes machine uptime.
A built-in outlet check valve ensures accurate lube delivery, every time. An alternative outlet on the face of the valve can be fitted with optional performance indicators, to make troubleshooting so much easier and more reliable.
A controller is essential to provide programmed lubrication cycles for optimal machine performance. A good controller will enable you to customize your lubrication time, pressure, cycle counts and machine counts for maximum precision and productivity.
The Graco GLC 4400 Multi-Purpose Controller does all that and more. It incorporates a simple icon- and menu-based user interface that is easy to setup and operate, saving valuable technician time. Further setup time savings – as well as reduced inspection time – are possible thanks to special operation modes.
Rugged and weatherproof, the GLC 4400 meets the stringent IP 69K protection requirements. It works with single line resistive, single line parallel, series progressive and dual line systems.
Graco offers a comprehensive array of accessories. These include pressure, proximity and cycle switches, which inform immediately if a system is not operational. The optional broken line indicator enables easy monitoring of whether the lubricant has reached the bearing. Further accessories like performance and magnetic visual indicators speed up troubleshooting to decrease machine downtime.
Ideal for any industry
Graco’s automatic lubrication systems can be found in all industries, such as these:
Mining, agriculture and construction equipment operates in the most rugged environments, so depend on reliable automatic lubrication equipment to keep the equipment running. Graco ensures that all these points are automatically lubricated while the equipment is working:
Automatic lubrication of the chassis of trucks and buses while they are running increases uptime and profitability, extends equipment component life, saves maintenance time, and lowers operating costs.
Food and beverage
The last thing that a company operating in the food and beverage sector wants is contamination of their processes with oil and grease. It could cause product spoilage, lost production, and increased operating costs. Graco offers automatic lubrication equipment that provides finely controlled delivery of lubricant without any risk of contamination through atmospheric misting. What’s more, its equipment is resistant to caustic washdowns that are used to clean machines and bottles.
Wind turbines are frequently located in tough environments subject to temperature extremes, salt spray and dust storms. They are also often in remote locations, such as offshore, where the cost of maintenance can be astronomical. For these reasons, efficient automatic lubrication is vital. Graco equipment lubricates the main bearings, blade pitch bearings, yaw bearings, gear tooth flanks and
the open gear teeth to reduce downtime and cut technician intervention to an absolute minimum.
Moving parts in a vessel’s engines, propeller shaft bearings, steering gears, winch drives, deck cranes and other equipment all depend on proper lubrication to function optimally – Contact Graco For more information go to www.graco.com To contact us, mail email@example.com
