DiamondFace, the microcrystalline diamond coating from EagleBurgmann, raises the reliability and performance of your mechanical seals several times over.
EagleBurgmann has established the high performance SHF mechanical seal for use in multi-stage high-pressure boiler feed pumps in power stations.
This successful mechanical seal is notable for a low rate of wear, minimal leakage and high availability, even at high peripheral speeds. It is extremely long lasting even in peak load power stations with frequently fluctuating loads. Years of experience in the design and practical use of a multitude of high-pressure feed pumps come out in this mechanical seal.
The reliability of gas seals depends on an adequate flow of clean dry gas at the seal. Gas supply systems take product gas from a higher-pressure stage of the compressor, filter the gas and use it to flush the seal. When the compressor is not running, the flow is interrupted and there is no source of high-pressure gas to protect the seal from contaminated product gas. This can pose a serious risk, because deposits at the seal can cause leakage or even damage the seal. In order to alleviate this problem, piston compressors/boosters driven by compressed air have been deployed in recent years to suck in filtered gas from the compressor, increase the pressure and use the gas to flush the seal.
EagleBurgmann’s newly developed double Cartex GSDN gas seal is the ideal solution for centrifugal pump applications at chemical plants and refineries. Users can install bi-directional gas-lubricated Cartex GSDN seals to standardize their new pumps or to recondition existing pumps which have conventional stuffing box packings or liquid-lubricated mechanical seals.
The EagleBurgmann type DR1 and DR2 Dry running seals are designed for agitators, mixers, reaction vessels, blowers, fans, etc. wherein shaft drive is located at the top of the vessel. The seal and seal faces are exposed to the gases/ vapors of the product and there is no liquid coming in contact with the seal and faces. That is why the Seal is called “Dry Deal”.
The APItex® series developed by EagleBurgmann includes single and double pusher type seals in cartridge design which are fully compliant with API 682 Category 1 Type A. These robust, reliable seals are designed to withstand process fluctuations and shaft deflection. The shrink-fitted seal faces and the floating seat mounting ensure dependable operation.
