German speck pumpen seals, speck pumpen models, speck pumpen prices

speck pumpen seals are sealing devices installed to prevent leakage between the pump shaft and the housing. Common shaft seal types include packing seals, mechanical seals, and dynamic seals. The shaft seal of a reciprocating pump is usually a packing seal. When transporting media where leakage is not permitted, a diaphragm reciprocating pump can be used. The shaft seals of rotary pumps (including vane pumps, rotor pumps, etc.) mainly include packing seals, mechanical seals, and dynamic seals.

speck pumpen seal principle

A mechanical seal is a shaft sealing device that achieves leak prevention by keeping one or several pairs of end faces, which slide relative to each other perpendicular to the shaft, in contact under the action of fluid pressure and the elastic force (or magnetic force) of the compensation mechanism, supplemented by auxiliary seals. A common mechanical seal structure consists of components such as the stationary ring (static ring), rotating ring (dynamic ring), elastic element spring seat, set screws, rotating ring auxiliary O-ring, and stationary ring auxiliary O-ring. Anti-rotation pins are fixed on the gland to prevent the stationary ring from rotating. The rotating ring and stationary ring can also be referred to as compensation rings or non-compensation rings depending on whether they have axial compensation capability.

speck pumpen seal system composition

1) Gland housing: In the past, gland housings for mechanical seals were stuffing boxes designed for soft packing seals. They are unsuitable for mechanical seals, not only because they are too small and have too narrow clearances, but also because their simple cylindrical shape is inappropriate. Standards for enlarged gland housings for mechanical seals have been established abroad. Furthermore, Durametallic Corporation in the United States and the Fluid Sealing Association (formerly the British Hydromechanics Research Group) are researching rational gland housings for mechanical seals. Their shapes should not only facilitate fluid flow and heat dissipation but also help remove solid particles, thereby creating a favorable environment for the seal. 2) Volatile emission control system: In the past, attention was focused only on eliminating visible fluid leaks, while neglecting the control of invisible volatile emissions. This has led to environmental pollution and poses hazards to equipment and personnel. Abroad, committees such as the Sealing Technology Committee of the Society of Tribologists and Lubrication Engineers (STLE) in the United States have developed guidelines for controlling volatile emissions from rotating machinery, compressors, and screw systems equipped with mechanical seals, including SP-30 (1994), SP-32 (1990), and SP-33 (1991). SP-30 is implemented in three stages. It clearly defines barrier fluids and buffer fluids, clarifying erroneous and confusing concepts. A barrier fluid is introduced between dual seals to completely block process fluid from leaking into the surrounding environment. The pressure of the barrier fluid is always higher than that of the sealed process fluid. A buffer fluid serves as a lubricant or cushioning agent between dual seals, and its pressure is always lower than that of the sealed process fluid. 3) Integration of auxiliary systems: Auxiliary systems for mechanical seals require integration, including cooling, heating, and flushing systems. Pump circulation needs optimization, and issues such as condition monitoring systems are being studied and resolved. The integration of auxiliary systems is specified in the API-682 standard. 4) Gas barrier seal system: In the past, liquid-blocking-liquid or liquid-blocking-gas configurations were commonly used in barrier seal systems. To simplify bulky barrier liquid systems, barrier gases are now used to block liquids or gases. In gas barrier seal systems, spiral groove gas seals with barrier gas, floating bushings with barrier gas, and other methods can be employed to seal both gases and liquids.

speck pumpen seal functions and applications

Engine: Crankshaft - front and rear crankshaft oil seals; Valve - valve oil seals (engine repair kit o O-rings) (distributor oil seal, water pump oil seal, balance shaft oil seal, oil pump oil seal...); Camshaft - camshaft oil seal; Transmission: Transmission - front and rear transmission oil seals; Shift lever oil seal (transmission repair kit o O-rings) (Transfer case - front and rear transfer case oil seals); Rear axle: Half shaft - rear half shaft oil seal; Differential - (front/rear) pinion oil seal; Rear wheel oil seal; Front wheel oil seal; Steering gear oil seal (steering gear repair kit o O-rings); Power steering booster oil seal (front half shaft oil seal). Oil seals are required wherever rotating housings contain liquid lubricants and connect to the exterior. Some are made of rubber, some of metal, but most are steel-cased rubber, such as rear crankshaft oil seals, front and rear transmission oil seals, left and right half shaft oil seals, final drive front oil seals, and air compressor crankshaft oil seals.
