Function and area of implementation

Can be used in chemical, petrochemical, food and other industries as well as in energetics, heating networks and utility services.

General technical characteristics, essence of invention

Face packing seals are the new generation of stuffing box seals that combine simplicity of radial packing seals with high sealing and durability of mechanical face seals.

Comparison with world analogues, main advantages of invention

Main advantages of the invention:

• reduction of energy losses on friction;
• saving of stuffing box packing;
• increased service life;
• reduced time costs and funds for maintenance (no need to regulate during operation);
• reduced leakages;                         
• friction pair is made from inexpensive materials, there is little sensitive to shaft run out sand misalignments and does not require precision machining;
• easy replacement of stuffing box packing ring without disassembling of aggregate.

Intellectual property protection status

Patent of Ukraine for utility models were obtained.

Market demand

Face packing seals can be used in a wide range of pressures and sliding velocities for sealing of neutral, slightly aggressive mediums for using in general and special industrial pumps in chemical, petrochemical, food and other industries as well as in energetics, heating networks and utility services.

Status of invention

Invention is implemented at industrial enterprises.
