Overview
A Mechanicalseal B74D is a robust shaft sealing unit designed for high-pressure centrifugal pumps. It features a hard ceramic or tungsten carbide rotating ring paired with a carbon stationary ring, utilizing precision-machined O-ring secondary seals to ensure leak-free operation in abrasive environments.
Application
- Oil & Gas: Centrifugal feed pumps and chemical transfer units.
- Chemical Processing: Agitator drives and acid circulation systems.
- Petrochemical: Boiler feed pumps and refinery crude pumps.
Precautions
- Operating temperature range: -20°C to +180°C.
- Maximum pressure limit: 25 bar.
- Ensure proper lubrication during startup to prevent dry running damage.
- Inspect seal faces for wear every 6 months under heavy load conditions.
