Description
The BM4L seal is an engineered product particularly suitable for use on vertical pumps and for atmospheric tanks in the absence of liquid between the faces. It is an economical solution due to the absence of flushing and works at atmospheric pressure. The particular design of the rings and the appropriate balancing have led to the development of a single dry seal suitable for working even at high speeds. In case of overpressures the seal allows correct functioning for at least eight hours at stuffing box conditions.
- Single balanced seal and floating containment bush
- Double direction of rotation
- Monolithic sealing rings
- Vent connections and control of physiological losses of the process side seal
- Flange and shaft sleeve designed to customer specifications
- Recommended for API 610 vertical pumps
- Solution developed to provide installations on existing machines
