SHV
Features
- Single seal in cartridge design
- Balanced
- Multiple springs
- Stationary spring loaded unit
- Shrink-fitted seal face
- Rugged mating ring
Advantages
- Deformation-optimized seal for high sliding velocities and high pressures
- Economical due to standardized inner components
- High flexibility due to adaptation of the connection parts to the pump seal chamber
- Insensitive to shaft deflections due to stationary design
- Pre-assembled unit for quick and easy installation
- Suitable for use in compliance with API 682, type ES
- Version with loose-fitted seal face available, for extreme applications
- Only small number of components
