  • Features of Water Pump Mechanical Seal


    Mechanical seal is a device used to solve the seal between the rotating shaft and the body. It is composed of at least a pair of end faces perpendicular to the axis of rotation under the action of the fluid pressure and the elastic force (or magnetic force) of the compensation mechanism and the auxi Read More

  • How to Install the Double Mechanical Seal


    The double-end mechanical seal has the characteristics of short seal axial size and compact structure, so it is especially suitable for occasions where the axial size is restricted. Due to the complex structure of the double mechanical seal, high technical requirements, and strict sealing performanc Read More

  • Basic Knowledge of Metal Bellows Mechanical Seal


    The metal bellows mechanical seal is a single-end, balanced, and arbitrary-rotation metal bellows seal. Since the moving ring O-ring and flexible graphite ring can not compensate, there is no resistance to the movement of the bellows, which is suitable for high temperature and high viscosity media. Read More

  • Performance Requirements and Technical Requirements of Mechanical Seals


    This requirement applies to centrifugal pumps and other similar rotary mechanical seals. The working parameters are: working pressure is 0---1.5691MPa (referring to the actual pressure in the sealed cavity); working temperature is -20--80℃ (referring to the actual internal temperature of the sealed Read More

  • What is Double Mechanical Seals


    Compared with the single end face mechanical seal, the double mechanical seal has a better sealing performance. It is suitable for the sealing of strong corrosion, high temperature, suspended particles and fiber media, gas media, flammable, explosive, volatile, and low viscosity media, and high vacu Read More
