Balance ratio Sliding pressure pG The balance ratio is a non-dimensional factor of the The term “sliding pressure” is understood to be the surface sealing gap geometries which converge in leakage mechanical seal and is defined as pressure on the two sealing faces which remains after direction – V-gap for externally pressurized seals – the subtracting all those forces that act on the seal face and value of k1 is > 0.5, while for sealing gap geometries which are balanced by hydraulic pressures. The sliding which diverge in leakage direction – A-gap for externally pressure is conditional on the pressure differential to be pressurized seals – the value of k1 < 0.5. For simplified sealed, the balance ratio, the pressure conditions inside calculations the value of k1 is generally taken to be 0.5. the sealing gap i.e.gap between the seal faces (pressure Under unfavourable conditions the sliding pressure can gradient factor) and the spring pressure.

Titanium nitride coatings are used as start-up protection for metallic seal faces on compressor seals (e. g. MDGS).

Leakage rate Q Calculated rates of leakage and power losses are not guaranteed values. They are statistical and calculated Formula for externally pressurized mechanical seals mean values which are determined on the basis of experience and extensive testing. The leakage rates and power losses which actually arise in a particular seal can be several times higher on account of factors that are impossible to quantify theoretically. As can be seen from formula, the leakage rate is mainly conditional on the actual gap width during operation. This depends in turn on many factors (see also gap width). Example calculation for a H7N/48 seal Factors influencing leakage The major factors with an influence on a mechanical seal’s leakage rate, correct functioning and reliability include:
• Machined finish of the sliding faces • Flatness of the sliding faces and flatness deviations caused by thermal or pressure-induced deformations • Machine vibrations or stability • Mode of operation of the plant • Characteristics of the medium to be sealed • Correct installation of the mechanical seal

You can benefit from our many years of experience Maintenance and expertise in all areas of seal technology, and our major store of practical knowledge. In the plant or in the service center, qualified Technical analysis & support fitters and technicians look after all the aspects of seal maintenance: installation, startup, servicing, A team of seal specialists is responsible for conversion, overhaul and repair. We record and rectifying process malfunctions or “bad actors”. document functionally relevant data (fault causes, The latest methods such as thermography or data measures for repair, costs). This means it is logging are used for diagnosing positions that are possible to assess seal operating times and critical for the operation of the system and for maintenance costs on a continuous basis, thereby working out measures to rectify them. In our defining measures for extending service intervals. research and development centers, we perform 2 realistic tests on test rigs or in original pumps. The objective is to extend the MTBF and to 6increase system serviceability by individual and On-site service constructive solutions. Our on-site service includes the components of an overhaul service, conversions and service container. We deploy a service unit directly on Service agreements your premises: equipped with the basic suite of seals or a stock of seals discussed with you in We offer our customers specific agreements advance, and staffed by qualified personnel. that can be combined from the six service On-site, our work includes producing the necessary modules. Whether for individual seal systems, gaskets, ensuring that the documentation is critical process elements, specific system areas complete and advising our customers on selecting or an extensive seal service for complete plants: 3and installing seals.
