In oil production
Multiphase pumps for the oil industry pump mixtures of crude oil, formation water and natural gas, in vastly differing concentrations and compositions. The pumps’ sensitive components include the mechanical seals. These are generally equipped with sophisticated flushing and lubricating systems to allow them to work without interruption. They prevent overheating due to dry running or erosion of the seal faces by abrasive media. DiamondFace mechanical seals for booster pumps also make things easier, as EagleBurgmann has demonstrated with its seals that are in use successfully under extreme conditions.
In power plant technology
With DiamondFace coated high-performance seals there is no possibility for electrochemical corrosion in feed water pumps. The technology not only makes dosing systems superfluous, but it also impresses with outstanding operating times. DiamondFace mechanical seals are the perfect match for high performance feed water pumps and are available for both conventional and nuclear power plants.
Numerous conventional and nuclear power plant operators already rely on this innovative sealing technology with DiamondFace.
On the high seas
Four booster pumps on each of five cruise liners were equipped with DiamondFace mechanical seals to guarantee safe and reliable alternation between the various grades of fuel used.
The initial situation was marked by the mechanical seals frequently running dry, resulting in overloading of the seal faces and secondary seals. The result of applying DiamondFace technology is clearly improved dry running and much longer service periods of up to 10,000 hours.
In microelectronics components production
The production of microelectronics components is a complex and demanding cleanroom process that requires a supply of totally pure process water.
With DiamondFace coating the mechanical seals, the contamination limits were easily undershot as the facing is subject to practically no wear, thus guaranteeing fault-free operation.
In ceramic production
Ceramic mold casting is one of the traditional ceramic molding processes. The mixing and dispersing process causes a sharp temperature rise in the machine and at the seal faces, causing the dispersion to adhere.
The low friction coefficient of the DiamondFace coating greatly reduces the rise in temperature, preventing adhesions and guaranteeing an interruption-free process.
In oil sand extraction
The exploitation of oil sand fields exposes the equipment used to the harshest conditions. The pumping equipment must be able to withstand an extremely abrasive mixture of oil, sand, water and steam. As a consequence, the service life of conventional mechanical seals is shortened due to insufficient lubrication and dry running caused by the abrasive solids content.
The application of mechanical seals with DiamondFace coating optimizes the dry running capability and extends operating periods several times over.
