Submerged Bearings

Many tough applications run completely underwater, partially submerged, or with washdowns. Often in these applications, caustics are also an issue. Therefore, it is important to have a bearing material that is dimensionally stable, can handle caustics, and can provide lubrication in various environments. Graphite-metal alloy bearings can be a solution here. Learn more about submerged bearings here.

Nickel-Impregnated Graphite Bushings

Nickel-impregnated graphite bushings can handle temperatures of up to 750°F/400°C in oxidizing environments and 1700°F/725°C in non-oxidizing/submerged environments, as well as handle low lubricity service and run-dry scenarios. This makes them a good match for pumps in tough services. Learn more here.

Graphite-Metal Alloy Bearings For Ovens

Oven Bearings generally present a two-part problem: high temperatures cook out bearing lubricants, and they are in tough-to-reach locations that make re-greasing difficult. Graphite-metal alloy bearings solve these problems using a maintenance-free, self-lubricating material. There are even FDA Acceptable graphite-metal alloy bearings available. Find out more about high temperature oven bearings here.

Graphite for Mechanical Seals

Typically seals require a harder carbon graphite. Here you can find information on material for seals.

Graphite-Metal Alloy Bushings for CO2 Pumps

Countries such as Brazil are increasingly reinjecting CO2 to meet carbon reduction goals, as can be read about in this Reuters Article. But pumping CO2 is no easy task. It is a low lubricity service, with a high possibility of flashing. Using a wear part material that is self-lubricating and non-galling to allow for low lubricity and flashing is essential. Graphite-metal alloy wear parts are proven in these applications- read more.

Improving Pump Efficiency with Graphite-Metal Alloy Wear Parts

Many metal and plastic wear parts require wide running clearances due to the possibility that touching might cause melting, galling, and even seizure. Graphite-metal alloy bushings and case rings allow tighter running clearances- this material is dimensionally stable, non-galling, and self-lubricating. These tighter running clearances translates into greater efficiency for the pump, leading to greater energy and expenditure savings. Learn more about how Graphite-metal alloy bearings can improve efficiency, including a case history.

Graphite-Metal Alloy Bushings for Fertilizer Pumps

Graphite-metal alloy bushings are a good solution for anyhdrous ammonia and urea pumps, used in the fertilizer process. Learn more about why these tough pump services can benefit from the use of this material versus metals and plastic wear parts. Read more
