GRAPHALLOY® Introduces NSF® Certified Grades For Pumps

Used in Pump Bushings and Bearings for Vertical and Horizontal Pumps

Graphite Metallizing Corporation, the manufacturer of self-lubricating GRAPHALLOY® bushing materials, is pleased to announce that NSF® International, has just certified two grades of GRAPHALLOY material for use in municipal well pumps and water treatment plant applications.

The two newly certified GRAPHALLOY Grades are certified to NSF/ANSI Standard 61 - “Drinking Water System Components/Health Effects” - and approved in the category for Multiple Water Contact Materials (MLTPL) up to 180˚F.

NSF certification is the result of Graphite Metallizing’s rigorous product testing to ensure the highest quality GRAPHALLOY products for the market. These newly certified grades are used in the manufacture of pump bushings and bearings for both vertical and horizontal pumps.

GRAPHALLOY is currently the product of choice for many deep well water pump applications in the western U.S., Hawaii and around the world.

NSF International is the independent, not-for-profit/non-governmental organization that provides materials evaluation, standards testing and product certification services involving public health and safety issues.

Graphite Metallizing Corporation, a global leader in the manufacture of self-lubricating bushings and bearings for almost a century, produces GRAPHALLOY, a graphite/metal alloy bearing material used in the manufacture of self-lubricating bearings and components for pumps, machinery, and process systems.

GRAPHALLOY® Bearings FDA Accepted for Food Processing Applications

Graphite Metallizing Corporation, the manufacturer of GRAPHALLOY^® bearings and bushings, announces that FDA accepted grades are available for food processing and commercial baking applications.

GRAPHALLOY, a graphite/metal alloy, is formed from molten metal, graphite and carbon. It is a uniform, solid, self-lubricating bushing and bearing material. GRAPHALLOY is widely used in bakery ovens, dryers, roasters, mixers, conveyors, freezers, sterilizers, grills, pumps, bottling plants and packaging equipment — anywhere grease/oil lubricated bearings or plastic bearings might fail.

Self-lubricating GRAPHALLOY bearings and bushings perform in temperature extremes of -450˚F to +750˚F and above (-240˚C to +400˚C and above) where conventional materials often fail. GRAPHALLOY bearings require minimal maintenance and can reduce downtime, resulting in uninterrupted production of food contact equipment. With a low coefficient of friction and high strength, GRAPHALLOY bearings deliver long life and are not subject to seizures, binding or sudden failure.

Equally important, GRAPHALLOY does not contain oil or grease and can be immersed in liquids without causing contamination of equipment or packaging. GRAPHALLOY bearings also withstand steam cleaning and pressure washing operations without any loss of lubrication or bearing performance.

GRAPHALLOY bushings are also used in municipal water systems, refineries, paper mills, waste-to-energy plants, glass plants, steel mills and power plants. Many grades are suitable for temperatures to 750˚F (400˚C) in air and special grades provide reliable service up to 1000˚F (538˚C) and higher in non-oxidizing atmospheres.
