Barrier Fluid Systems
Barrier fluid systems are designed to supply barrier fluid (water) to the interseal space of a double mechanical seal at a pressure higher than the pressure inside the reactor. This prevents any product leakage from the reactor into the environment and eliminates seal overheating. Each system is custom-engineered to meet the customer’s requirements.
The system consists of a reservoir filled with barrier fluid and equipped with instrumentation to monitor the fluid’s pressure, temperature and level.
The reservoir incorporates a built-in cooling coil for the barrier fluid. A circulation pump circulates the fluid through the reservoir–mechanical seal circuit.
The reservoir is periodically topped up using a hand pump to compensate for normal barrier fluid leakage.
The maintenance interval depends on the operating conditions of the mechanical seals and is 24,000 hours under constant load or 5 years under intermittent loading.
Advantages
- Conveniently located detachable connections
- Use of flexible high-pressure hoses
- Minimal installation work required for piping reconfiguration
- Maximum accessibility for installation and maintenance of the hydraulic system during test bench operation
- Collection of any leakage during operation
