Stationary mechanical seals

Our company has been manufacturing Stationary Mechanical Seal since 1970, targeting at trouble shooting. We are making improvements while expanding the application of stationary mechanical seal. Today you will find our achievements on a variety of applications mainly in oil refining and petrochemical processes.

Features

The stationary mechanical seal can absorb the distortion that due to high temperature, high pressure and poor stuffing box precision by the spring. It maintains perpendicularity of sliding surface with excellent seal performance.
In addition, because spring is placed at atmosphere side, there will be no clogging due to slurry etc., good working status is realized. Also, there are no wear and tear due to O-ring, shaft and sleeve.
Stationary Mechanical Seal is useful for prolonging the life of the seal, and it has wide range of application.

(1) Slurry Tolerable
As spring does not have liquid contact, the seal quality is retained even for slurry liquid.

(2) Old equipment support
It will not be affected by the distortion of the casing due to aging of the machine, so it is useful for counter-measurement support.

(3) Excellent heat resistance
It will not be affected by the distortion of the casing due to heat. In addition, the heat from shaft does not directly transmitted to floating packing, this thermal structure leads to excellent quality of heat resistance.

(4) Excellent pressure resistance
The pressure will not distort the casing and therefore it has excellent quality of pressure resistance.

(5) Corresponding to high-speed condition
Spring is not affected by the centrifugal forces located at the stationary side, so it is adapted for high-speed rotation use.

Stationary Bellows Seal

It is a kind of stationary type of welded bellows seal which is for high temperature petroleum refining process fluid. By employing stationary structure, there is less susceptible to thermal distortion, it ensures the stable traceability, and delivers outstanding sealing performance.

Inconel 718
By adopting a standard Inconel 718 bellows core high fatigue strength, characteristics of corrosion resistance, heat resistance, and spring loading is excellent.

Damper Spring
By “employing damper spring” standard to supress the resonance of bellows between bellows and baffle, stable seal performance and excellent durability are achieved.

Quenching Efficiency
As quenching seal, it adopts auxiliary seal ‘ABC Ring’ as standard seal according to split floating ring. As quench fluid flows through the baffles which are provided at inner of bellows, near the sliding surface, it has effective cooling, heat insulation and cleaning functions.

Graphite Foil
As an alternative to the synthetic rubber O-rings and PTFE packing, by employing Graphite Foil with excellent heat and chemical resistance feature, it achieves application for a wide rage of temperature. Sliding materials is replaceable because of its Graphite Foil Mount structure and keeps good precision of sliding surface even under high temperature or extremely low temperature.

Sliding Materials
Sliding Materials deliver excellent characteristics of abrasion and blister resistance by adopting SiC and hard-impregnated non-rigid carbon.

Regarding Costs
As the operation is possible even without flushing cooler in high temperature specifications, facilities cost therefore is reduced and maintenance labour-saving is improved.

Dry Seal

To drive the mechanical seal, it is essential to put the lubricant film on the sliding surface, if seal the gas zone of top of the agitator, double mechanical seal system has been widely adopted. However, it is found that by using liquid seal, the product purity decreases due to slightly liquid leakage. In addition, the adverse effect on ancillary equipment setup and management are appointed out. Therefore, the need for dry seals is increasing. The variable dry seals developed by our company have contributed to stable quality of manufacturing processes at user side, simplicity of ancillary equipment and maintenance reduction.

Features

(1) Free from Contamination
Since seal liquid is not employed; there will be no seal liquid contamination in the products. Therefore, it prevents contamination. In addition, the contamination of visible debris in products is significantly reduced when using gland packing. There are several achievements in PL (Product Liability method) solution for pharmaceutical and food, anti-bacteria solution.

(2) Reduced facility costs
It does not require ancillary equipment such as seal pots and circulation system for sealing liquid supply. The facility costs therefore are reduced.

(3) Reduced Maintenance
It does not require maintenance work, like gland packing retightening, and sealing liquid management, therefore, it greatly reduces the burden of daily maintenance.

(4) Response to positive and negative pressure conditions
From vacuum to positive pressure limit, it delivers excellent performance of seal.

(5) Simple Structure
It is a simple structure by deploying spring, for example, outside the machine. It helps to eliminate the jam of distillation in the vessel. In addition, the cleaning is easy to perform.
