single conical helical spring, unbalanced seal with '0' ring as secondary sealing member. Various seal face materials and elastomers can be offered for wide service application. As the torque transmission is done by conical helical spring these seals are dependent of the direction of rotation. Direction of rotation is seen from the drive end of the shaft. Clockwise rotating shaft requires right handed spring and anticlockwise rotating shaft requires left-handed spring. For easier fitting, the conical helical spring should be pushed on the shaft with a twisting motion in the sense of the spring unwinding. This movement enlarges the diameter of the spring, enabling easy fitment.

Temperature t : – 20 ... +250O C (API plan 23)
Velocity v : more then 50 m/sec

This is a unique seal developed to meet stringent technical requirements of Boiler feed water pumps.

Rotating mating ring design makes it suitable for high speed application and avoids critical requirments of stuffing box face squareness.

Both the faces are having strong positive drive and locking arrangment which make seal very strong and sturdy.

Thermodynamic circulation grooves inscribed on the rotating faces boost the cooling of the sliding faces by reducing the coefficient of friction and protecting the seal against thermal over loading.

Increased collent flow effected by the pumping screws and the fluid guiding channel combine to force the cold water into the gap between seal ring and mating ring, blowing out gas bubbles and dirt praticles and picking up frictional heat.

In view of risk of dynamic distortion because of high sliding velocity of over 25 m/sec the springs are located in the stationary part.

Dry Seals

  /> </div>
<div class=

Function:

The shaft seal type SPE is a single-acting bidirectional mechanical seal. It was specially designed for sealing against abrasive products and is used for flooded side entering applications. The seal rings are surrounded, lubricated and cooled by the product. The hydraulic design and the preload of the springs are arranged in such a way that the seal gap of the highly wear-resistant pair of seal rings (Silicon carbide) is reliably lubricated. This makes any hydraulic installation superfluous, i.e. in the plant no additional seal liquid supply systems need be used. The temperature in the seal gap is so low that no evaporation of the fluid in the seal gap occurs. Springs, drive pin and o-rings are protected against caking.

Application:

The SPE is the most used mechanical seal in FGD-agitators worldwide. Special metallic materials for product-wetted components give reliable protection against corrosion, also in the use of aggressive media. If highly aggressive media are used and the highest safety conditions are necessary, the product-wetted components can be manufactured in a special plastic which is highly corrosion-proved.

The main areas of application are:

  • Flue gas desulfurization (FGD)
  • Hydrometallurgy
  • Pharmacy
  • Biotechnology

 

Materials:

Housing: Stainless steel 
Product-wetted parts: Stainless steel, Hastelloy, Titanium, special materials
Seal rings: Carbon, Silicon Carbide, Tungsten Carbide, etc
O-rings: Viton, EPDM, Perfluor elastomers, special elastic materials
FDA-approval: Possible for all product-wetted parts

Application Limits :

Vessel pressure: Vacuum ...16 bar (abs.) 
Vessel temperature:-50 … +200° C
Shaft size: 40 ... 300 mm
Sliding speed: 5 m/s

Quality :

SEAL PROOF is supplied ready for installation as a cartridge unit. Prior to delivery every mechanical seal is dynamically tested under process conditions according to an internal QM System and receives a test certificate. The seal type SPE is designed to optimum GMP requirements and is TÜV certified for applications in hazardous.

QUALITY:

Seal Proof keeps a very keen eye on Quality control at every stage during the manufacturing of each and every product.

Seal Proof seal less Magnetic Driven Pump :

Seal Proof centrifugal Magnetic pump Comes in PVDF , P.P. & Stainless Steel, is now introduced in response to the process industry's growing concern for the environment, the safety of plant personnel, and the high ongoing cost of mechanical seal maintenance. It is an ideal pump for use in installations handling toxic, noxious, inflammable or corrosive liquids such as NOx or freon gas where leakage to atmosphere cannot be tolerated

Seal less :

Pump age is hermetically sealed in a thick, rugged stainless steel pump casing. magnetically driven, seal less pump- construction assures you of leak freeness. The Pump never soils surroundings, but maintains safe and clean environment.

Drastically saves Maintenance Costs :

Silicon Carbide wet bearings, the core of pump, extensively reduce wear and corrosion, and provide extremely long life ( interchangeable front and rear). It allows customers to hold a minimum number of parts, and spares them many a maintenance work for a long period of time.

Seal - less features make these pumps perfect for environments subject to federal regulations
