These are Special mechanical seals having standard design arrangements with less varying sizes. These are usually used in some standard pumps and industries like grundfous pump, textile industries, boiler feed pumps. These seals have some special design and arrangement that fits to particular pump and application to reduce cost, space and time.
Mechanical seal designed is a unique seal developed to meet stringent technical requirements of Boiler feed water pumps. Rotating stationary ring design makes it suitable for high speed application & avoids critical requirement of stuffing box face squareness. Both the faces are having strong positive drive & locking arrangement 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 coolant flow effected by the pumping screw & the fluid guiding channel combine to force the cold water into the gap between dynamic ring & stationary ring, blowing out gas bubbles and dirt particles & picking up frictional heat. In view of risk dynamic distortion because of high sliding velocity of over 25 m/sec the springs are located in the stationary part.
