Mechanical seals - Import export

Designing pumps, compressors and other equipment, the aim is to prevent leakage into that can emerge at any point by liquids or gases. To solve this problem very often are used mechanical seals. To obtain the desired sealing function and an adequate lifetime of the mechanical seal,the preconditions must be fulfilled within the permitted tolerances at any time: parallelism of the sealing surfaces perpendicularity of the seal faces to the rotation axis elastic contact of the sealing surfaces existence of a lubricating film between the two sealing surfaces Usually the sealing capability of the mechanical seal against shaft or housing is obtained with the secondary seals, as O-rings, bellows or boots In conjunction with the International Organization for Standardization (ISO) and their standards (ISO 3069), the German Industrial Standard (DIN) published proposals for standard mechanical seals with DIN EN 12756 (24960).

Heavy Duty Grease Description Castrol Molub-Alloy 3136 has been developed for use in applications with high loads, adverse environmental influences and low movement speeds. It is successfully used in all known heavy industries such as steel, mining or construction. Castrol Molub-Alloy 3136 is a mineral oil-based lithium soap grease. It has a good sealing effect against contamination if mechanical seals are damaged or missing (sealing grease collar on the bearing). Castrol Molub-Alloy 3136 provides effective protection against corrosion and is resistant to aging. It is free of heavy metals such as antimony and lead. Light-colored solid lubricants offer excellent emergency running properties in the event of a lack of lubricant.

Castrol Molub-Alloy 777 NG series (05/20/2021) High-duty lubricating greases Description Castrol Molub-Alloy 777 NG high-duty lubricating grease was developed for high loads in unfavorable environmental conditions . It is manufactured and additived in such a way that it can withstand shock and heavy loads such as those found in the steel industry or in the construction industry, mining and forestry. To produce Castrol Molub-Alloy 777 NG, a mixture of high viscosity mineral oils and polymers are used, which form a tough lubricating film that can withstand shock loads and vibrations. The shear-stable thickener has a very good sealing effect against contamination if mechanical seals are damaged or missing (sealing grease collar on the bearing). The grease contains solid lubricants whose structure has been selected to meet the requirements of harsh operation in heavy industry . It shows a good affinity for metallic surfaces.
