Product Applications:
●Applied to tandem or double-face dry-gas seals for pumps.
●Supplies clean, dry gas at specified pressure and flow rate to satisfy operating requirements of dry-gas seals.
●Monitors seal operating status and triggers alarm prompts for shutdown maintenance or seal replacement.
Special Design:
●Custom-designed and manufactured according to user-specified requirements.
Applicable Flushing Scheme:
●Suitable for mechanical-seal auxiliary-system: API-682 Plan 72, Plan 74, Plan 75, Plan 76
Materials and Configuration:
Serial number | Configuration | function |
1 | Filter | Handling particles in the gas meets the operational requirements of the booster pump， |
2 | Self-operated pressure regulating valve | Stabilize the pressure of the gas source to the set value, typically in conjunction with a filter |
3 | Check valve | Prevent the process medium from leaking into the nitrogen pipeline network |
4 | Leakage collection tank | Collect the process medium leaking from the seal |
5 | flow meter | The monitoring system flow is generally integrated with the flow transmitter |
6 | level gauge | Monitor the liquid level of the leakage collection tank |
7 | Pressure switch/pressure transmitter | Monitor the system pressure and sends signals to the central control room |
8 | Flow switch/flow transmitter | Monitor the system flow and transmit it to the central control room |
9 | Liquid level switch/liquid level transmitter | Monitor the liquid level of the leakage collection tank and transmit it to the central control room |
11 | Pressure gauge (optional) | Monitor system pressure |
