Features
- The pumped media never leaks to the atmosphere unless the reservoir pressure is lost.
- A nitrogen source is required for pressurization.
- Provision of cooling coil inside the reservoir or an external water or air cooler takes care of the heat removal.
- Uses an internal circulating device to ensure barrier liquid circulation.
- Barrier liquid enters the process medium through the inner seal faces.
Application
- For services where product dilution is acceptable.
- For services where media is unsuitable for lubricating the inner seal faces.
- For barrier pressures up to16 bar (232 PSI).
Remarks, checkpoints
- Always ensure that the source pressure is higher than the desired barrier pressure.
- Vent the system before start-up. Later ensure that the vent line always remains closed.
- Sense the seal inlet and outlet line temperatures. Difference in the temperatures is an indication of proper flow.
- Decrease in the reservoir level is an indication of inboard or/and outboard seal leakage.
- Ensure that the barrier pressure is always higher than the seal chamber pressure by at least 1.4 bar (20 PSI).
- For barrier pressures above 16 bar (232 PSI) use Plan 53B, 53C or 54.
- Check with the process engineer if product contamination is acceptable.
- Ensure the compatibility of barrier liquid with the pump media.
Pump media characteristics
- Suspended solids
- Polymerizing and contaminated media
- Poor lubrication properties
- Hazardous / environmentally harmful
- Leakage may form solids
- Close to vaporization point
- Can tolerate dilution with barrier media
Location, function
- Between seals
- Barrier system (psealchamber < pbetweenseals)
- Lubrication, flushing and cooling for both inboard as well as outboard seals.
