Cartridge mechanical seal is assembled by the rotary ring, stationary ring, spring, secondary seal( o rings, PTFE), gland and other mechanical seal parts together as a collection, known as the cartridge seal, sometimes also called the cartridge mechanical seal.
Advantage of Single Cartridge Seals
- ready-to-install: components include rotating components, bushings and glands
- gage bolts applied for the most gland box
- easy to replace the packing or bearing
- easy to install in uneasy install place
- Used for longer time than non-cartridge mechanical seal
- Features of Single Cartridge Seals
- faster and easier replacement of pump shaft seals
- less downtime
- reliable start-up after a sealing change
- Material of Single Cartridge SealsWhen a single cartridge seals used in the oil-filled motor, it is not only necessary to prevent the machine outside the impurities, sand and water to enter, but also to prevent the leakage of oil within the machine ,So sealing requirements is higher, sealing ring material requirements need to be good, its sealing face material is made of tungsten carbide or silicon carbide. If it is installed on the shaft of the water-filled motor shaft, it only requires sand control. The sealing ring can be made of alumina ceramic, silicon nitride or other harder materials, so the cost is relatively low.
Recommended applications of Single Cartridge SealsGeneral industrial applications including chemical processing, food and beverage, petrochemical processing, pharmaceutical, wastewater and power generation.
Centrifugal pump, Chemical pump, Slurry pump, Mixer, Agitator, Circulation pump, Submersible electric pump, Reactor, Oil pump etc.
Difference between Cartridge mechanical seal and non-cartridge mechanical seal
- Cartridge mechanical seal has a sleeve and gland; non-cartridge seals only have the rotary and stationary ring.
- The installation error rate of the Common non-cartridge mechanical sea is higher than the cartridge mechanical seal. Therefore, use cartridge shaft seal can greatly reduce the occurrence of mechanical seal failure.
- Since the cartridge mechanical seal does not require any adjustment of the mechanical seal by the installer (such as spring, sealing surface, etc.), only the bolts need to be tightened, which greatly improves the reliability of the mechanical seal installation.
