Germany SEEGER seals SEEGER models SEEGER prices

SEEGER seals are typical representatives of oil seals; generally, the term "oil seal" refers to skeleton oil seals. The function of an oil seal is generally to isolate components requiring lubrication within transmission parts from the external environment, preventing lubricating oil leakage. The skeleton acts like rebar in concrete components, providing reinforcement and enabling the oil seal to maintain its shape and tension. Based on structural form, they can be divided into single-lip skeleton oil seals and double-lip skeleton oil seals. The secondary lip of a double-lip skeleton oil seal serves a dust-proof function, preventing external dust, impurities, etc., from entering the machine interior. Based on skeleton type, they can be divided into inner-covered skeleton oil seals, exposed skeleton oil seals, and assembled oil seals. Based on operating conditions, they can be divided into rotary skeleton oil seals and reciprocating skeleton oil seals. Used for gasoline engine crankshafts, diesel engine crankshafts, gearboxes, differentials, shock absorbers, engines, axles, and other locations.

SEEGER seal features

1) No need to measure the seal working length during installation; 2) The shaft can be adjusted at any time; 3) Leakage during startup will not occur because the seal has been pre-tested; 4) During installation, only the clamping seal cover bolts need to be fitted, making assembly quality easy to ensure; 5) Protects the sealing surface from contamination by debris or damage due to operational errors before installation or startup; 6) Can be readjusted after thermal expansion of the machinery; 7) Self-centering via fit; 8) Easy to remove the seal for cleaning and inspection without disassembling the pump equipment. The API682 standard recommends cartridge mechanical seals for all mechanical seals.

SEEGER seal startup preparation

1) Comprehensively check whether the mechanical seal, auxiliary devices, and pipeline installations are complete and comply with technical requirements. 2) Perform a static pressure test before starting the mechanical seal to check for leakage. If there is significant leakage, identify the cause and eliminate it. If still ineffective, disassemble for inspection and reinstall. Generally, the static pressure test pressure is 2~3 kg/cm². 3) Rotate the pump according to its direction of rotation to check if it is light and uniform. If rotation is difficult or stuck, check whether assembly dimensions are incorrect or installation is unreasonable.

SEEGER seal troubleshooting

1) Main factors causing oil seal leakage: Poor sealing of the oil seal is the primary factor causing oil leakage. When the shaft wears and forms grooves, even replacing it with a new oil seal may not achieve proper sealing. This is due to reduced contact pressure between the oil seal lip and the shaft, resulting in insufficient interference fit between the installed oil seal lip diameter and the shaft diameter. Taking the crankshaft oil seal of the S195 diesel engine as an example, the main reasons for poor sealing are analyzed as follows: (1) Poor manufacturing quality of the oil seal; (2) Poor quality of the shaft or bearing; (3) Improper use and maintenance; (4) Improper installation; (5) Improper storage, leading to adverse effects from environmental contamination. 2) Countermeasures for oil leakage due to poor oil seal sealing: Acquire basic knowledge to identify inferior products and purchase high-quality, standard-compliant oil seals. During installation, if the outer surface of the shaft diameter has low roughness or defects such as rust spots, corrosion, or burrs, polish it smooth with fine sandpaper or an oil stone. Apply clean engine oil or lubricating grease to the oil seal lip or the corresponding position on the shaft diameter. Apply sealant to the outer circumference of the oil seal. Wrap the keyway area on the shaft with hard paper to avoid scratching the oil seal lip. Use a special tool to rotate and press the oil seal inward. Never hammer or force it in, to prevent deformation of the oil seal or spring breakage leading to failure. If lip flipping, spring detachment, or oil seal skewing occurs, it must be removed and reinstalled. Note: Do not arbitrarily tighten the inner spring when the shaft diameter is not worn and the oil seal spring tension is sufficient. Oil seals used in machinery generally operate under harsh conditions, with large environmental temperature differences, abundant dust, and frequent vibration causing constantly changing stress on components. Therefore, frequent inspection, maintenance, and servicing are required. If the shaft diameter and bearing are severely worn, or if the oil seal rubber is aged or the spring has failed, repair and replace the corresponding parts promptly. Troubleshoot abnormal heating in components or assemblies immediately. Avoid mechanical overspeeding and overloading to prevent increased oil seal lip temperature, rubber aging, and premature lip wear. Regularly check the engine oil level. If the engine oil contains excessive impurities, such as alloy powder or metal shavings, completely replace it with new oil. The brand and quality of the replacement oil must meet seasonal requirements. It is recommended to add Metraile Super Sealant & Lubricant to the engine oil. It is an excellent gearbox additive that forms an inert material film on components, which can reduce oil seal leakage, extend the service life of oil seal gears, and reduce gearbox noise. The use of this Metraile super sealant lubricant will not contaminate or degrade the oil.
