Vertical or Side-Entry, GRAPHALLOY Mixes It Up!

Industrial mixer manufacturers have been using self-lubricating GRAPHALLOY bushings for decades, especially in high-temperature environments.

That’s why when it came to choosing a bearing for a newly designed side-entry tank mixer, a major manufacturer decided to put GRAPHALLOY bushings to the test. Since this mixer was for a brewery application (part of the beer making process), the bushings needed to be oil-free, capable of being submerged and FDA acceptable.

Side-entering mixers work efficiently when a tank is too large for convenient installation of a top-entering mixer or when headroom is severely limited.

The company had been using GRAPHALLOY bushings in their various industrial mixers for many years and were pleased with the long life and low maintenance. Prior to using GRAPHALLOY, they had used a glass-filled Teflon material but their customers complained about the short life of these bushings.

Their new mixer is a high-efficiency, robust side-entry mixer designed for applications from 10,000 to 1,000,000 gallons, speed is 154 RPM, and temperature is 200°F.

Working with Graphite Metallizing engineers, they purchased thirteen pieces of GRAPHALLOY FDA acceptable bushings and installed them in the mixers in their brewery customer’s tanks.

John Warhoover Joins Sales Team at Graphite Metallizing Corporation

Graphite Metallizing Corporation, the manufacturer of self-lubricating GRAPHALLOY® bushing materials for pumps and process equipment, has appointed John Warhoover as Territory Sales Manager for Missouri, Southern Illinois, Kansas, Oklahoma, Nebraska, Western Iowa, and Arkansas.

Warhoover holds a B.S. degree in Industrial Engineering Technology from Southeastern Missouri State University. With nearly thirty years of experience in sales and engineering, he previously served as Regional Director of Sales and Technical Support at Rotating Equipment Repair and Senior Sales Engineer at Weir Minerals. He will be based out of his Missouri office.

“John brings extensive rotating equipment and, particularly, pump experience to our sales team,” said Eben Walker, General Manager of Graphite Metallizing. "He can help our customers use GRAPHALLOY to achieve greater equipment reliability.”

Graphite Metallizing Corporation of Yonkers, NY has been solving tough bearing problems for over 100 years. The company began in 1913 when two engineers developed a method for putting molten metal into carbon to create a new material called GRAPHALLOY, a graphite/metal alloy.

Used in the manufacture of bushings, bearings and other components for machinery and process equipment, GRAPHALLOY can be the solution to the toughest bearing, bushing, thrust washer, cam follower, or pillow block bearing design problem. It is available in over 100 grades with specific properties that meet a wide range of engineering solutions and specifications. FDA accepted grades of GRAPHALLOY are available for use in food service equipment. NSF® International has certified two grades of GRAPHALLOY material for use in municipal well pumps and water treatment plant applications. 
  
GRAPHALLOY bearings have operated for twenty years and longer in some applications. Standard designs are available but most GRAPHALLOY products are custom designed to the unique requirements of the specific application. Graphite Metallizing Corporation is ISO certified.

Coal-Fired Power Plant Slashes Maintenance Time with GRAPHALLOY Bushings

The conditions inside of a coal-fired power plant can place heavy stress on components. The dampers and burners have to deal with high temperatures and the presence of particulate. Bearings functioning in this environment have to be durable and must be able to operate without frequent maintenance.

This was not the case at one North American coal plant. The plant manager and his staff spent too much time maintaining the bearings inside the wind boxes that control the air supply to the combustion process. The bearings still failed regularly despite hours of work each week. Bearing failure meant that the combustion mix had fluctuated, leading to damaged boiler tubes, higher emissions and increased fuel costs.

By switching from lubrication-hungry roller-element bearings to GRAPHALLOY self-lubricating bushings, the plant greatly reduced maintenance demands while achieving a more predictable combustion mix. Click here to read more...

GRAPHALLOY® Solves Frequent Failures in Petrochemical Plants’ Multi-Stage Pumps

GRAPHALLOY self-lubricating bushings and wear rings are non-galling, withstand high temperatures, and are compatible with a variety of harsh chemicals. One petrochemical manufacturing plant greatly improved MTBF by converting two pumps in Tert-Butyl Alcohol service to GRAPHALLOY. These multistage pumps are used to transfer TBA at a temperature of 110°F.

GRAPHALLOY® Exhibiting at the 2015 ACHEMA World Forum

Graphite Metallizing Corporation, the manufacturer of self- lubricating GRAPHALLOY® bushing materials, will be an exhibitor at the ACHEMA World Forum in Frankfort, Germany. This trade show runs from June 15 – June 19 and is considered to be the leading forum for chemical engineering and the process industry.

Graphite Metallizing will be located in Hall 8.0, Stand H84. Representatives will be discussing two exciting new business initiatives. The first is the creation of a new headquarter office in the U.K. to support design applications in the European Union. The second initiative is the introduction of an expanded line of self-lubricating bearings for petrochemical and power pumps along with a full line of bearings for harsh environments.

GRAPHALLOY pump bearings have been granted Water Regulations Advisory Scheme (WRAS) approval. These bearings are used in municipal water system pumps and can operate for more than 10 years.

The Advantages of Nickel GRAPHALLOY®

Nickel GRAPHALLOY^® is a premium grade that provides superior corrosion resistance. It offers excellent long duration run-dry capability and high temperature ratings. Nickel GRAPHALLOY is the best choice for demanding pump applications, especially when yellow metals are not a viable option.

Nickel GRAPHALLOY® Bushings

 Nickel GRAPHALLOY is also:
• self-lubricating
• non-galling
• dimensionally stable

Typical Nickel GRAPHALLOY Grades:

GM 111.3
GM 119.3
GM 616.3

GRAPHALLOY® Self-Lubricating Bushings Will Not Seize

The environment in a rubber curing autoclave is 300ºF (150ºC) and has live high pressure steam. The grease-lubricated roller bearings were failing due to high heat and moisture,  causing interruptions in production. When a bearing failed, production was stopped due to the short shelf life of uncured rubber. 

GRAPHALLOY® bushings were installed and, after more than one year, there has been no production interruptions. If replacement is necessary, it can be done during scheduled outages because self-lubricating GRAPHALLOY will not seize the shaft.

GRAPHALLOY for Bakery Applications

High temperature GRAPHALLOY® bushings have been the choice of oven manufacturers for many years. GRAPHALLOY bushings extend bearing life and reduce maintenance costs for bakeries in temperatures reaching 1000° F (535° C). GRAPHALLOY may be the answer to the most difficult operating problems.

The Food and Drug Administration (FDA) has accepted GRAPHALLOY for "repeat use in food contact equipment" in bakery ovens, pumps, mixers and conveyors. Ovens and conveyors, in particular, undergo high heat and continuous operation that challenge the life and durability of critical components. Self lubricating GRAPHALLOY bushings and bearings perform in temperature extremes...when conventional materials fail.

GRAPHALLOY, a graphite/metal alloy, prevents unnecessary downtime and lost production. It also survives wash down conditions common in many food applications. With its low coefficient of friction and high strength, GRAPHALLOY bearings deliver long life and are not subject to seizures binding or sudden failure. In addition, the high temperature, self lubricating capabilities of GRAPHALLOY bushings reduce maintenance costs
