John Crane FBD Pump Single Spring Seal 16mm 100mm Rubber Bellows

Features:

FBD mechanical seal series is uneasy to be blocked due to its single spring structure. It has advanced rotating ring floatability so that reduced compensational resistance. This series is suitable for oil, water and other weak corrosive medium.

With full enclosed elastomer bellows design
Insensitive to shaft play and run out
Bellows should not twist due to bi-directional and robust drive
Single seal and single spring
Conform with DIN24960 standard.

Operating Limited:

Material:

Advantages:

• Spring unit averted from the product so no sticking and clogging of the springs
• Safe operation (no fractures) because of seal face locking by square pin
• Suitable for pressure reversals
• Operation in vacuum without additional seat locking possible
• No damage of the shaft by a dynamically loaded O-Ring
• Small installation sizes
• Best suitable for conversions, no adaptations of the pump
• Insensitive to solid containing and abrasive media
• Advantages of a balanced seal even with plain shafts
• Insensitive to shaft movements because of the stationary design

Application:

• Water and waste water technology
• Chemical industry
• Refining technology
• Dirty, abrasive and solid containing media
• Fugitive hydrocarbons (no API seal!)
• Sticky and stringy media
• Chemical standard pumps
• Sewage pumps

Fixing and Applying Directions of Mechanical Seals

1. Select Appropriate mechanical seal to match the materials according to work conditions and host machine equipment.
2. The radial acting deviation for the shaft(shaft sleeve) of the installed mechanical seal shall be 0.04mm by maximum
while the axial movement value of the rotor shall be no more than 0.1mm.
3. The seal cover (or shaft cover) of the stationary ring of the installed mechanical seals,the vertical degree of the seal
face should be 0.04mm by maximum.
4. When installing the mechanical seals,the shaft(shaft sleeve),seal chamber,seal face as well as the mechanical seal
must be cleaned in order to keep from any medium to sealing part.
5. When conveying medium of over high or low temperature,with medium which are easy catch fire,easy for explosion.
Related mechanical seal standards must be referred to take appropriate measures such as quench,rinsing,coolong and
filtrating.
6. Appropricate lubrication must be choosen when mechanical seal is installed.The installment size of the mechanical
seal must be guaranteed to the installment instruction.
7. Before the machine starts running,the hermetic compartment shall be full of medium and well lubricated.Dry friction
which may lead to the damage of the air-tightness is strict forbidden.
