Metal Bellow Seal
The "LE-CON designed various types of "metal bellow" seals for high temperature moderate pressure applications
pumps. Like chemical, petrochemical and refinery process unit, this seals are independence of direction of rotation
and suitable for process services requiring corrosion resistance.
Edge welded Metal bellow seals are constructed by series of diaphragm together to form a bellow unit. The bellow
unit eliminates the need of springs and provides flexibility to the seal in addition compensates for seal face wear.
This seal is available in two types of elastomer rubber o ring & grafoil to be use in extreme temperature conditions.
The concept is for stock realization, Easy of instillation with strength. Provides firm grip on the rotating element.

Thermosiphon & Cyclon Separator
This system thermosiphon vessel connects and
balances the pressure with agitated kettle, which is
the main elements of mechanical seal circulation
protection system together with mechanical seal.
Cyclon SeparatorCyclone Separator is used for separating solid particles from the liquid. Clean
liquid (about 80%) is sent to seal chamber and solid particles with very little
liquid (about 20%) is sent back to suction of the pump.
Operating Limits :
Density of solid particles has to be more
than liquid.
Maximum solid content > 10% by weight
Max. viscosity of liquid - 20 centistokes.
Pressure differential desired - 2 to 8.5 bar.
Technical Specification :
Size : 1/2", Max. Temp - 125°C,
Max. pressure - 60 bar
Material of Construction :
Hardware - SS 304/SS 316
Packing - Teflon.

Thermosiphon
The vessel is used for the storage, pressure maintenance and cooling of buffer fluid in cartridge mechanical seal.
Through the pressure implement, inputting the nitrogen or compressed air into balance vessel, making the pressure
0.05-0.1 MPA higher than that inside medium and insuring the normal operation of cartridge mechanical seal.
The standard prescribed agitated device-mechanical seal circulation protection system and it's methods, functions,
procedures, preferred principals and technical provision. For the agitated device the applicable design pressure is -
0.1-16 MPA and the temperature is -20°c~+300°c The mechanical seal of agitated shaft, processing the function of
lubrication, temperature control, voltage regulation. The working mode can be classified forced circulation and heat
convection circulation, and mainly composed by storage tank, pressure vessel, circulation pump, valve and control
instrument.
