- Replaces Bell & Gossett and Armstrong seal/bearing assemblies
- Made from die cast aluminum or cast iron
- Ensures correct alignment with motor shaft for longer life
Specifications
-
Compatible Lubricant: Grease
-
Item Model Number: BRG-F-200
-
Engineered for Durability
Built to ASME standards with a rugged steel shell and butyl rubber diaphragm to ensure long-lasting separation of air and water, reducing the risk of corrosion and waterlogging.
-
Ideal for Hydronic Systems
With a 79-gallon capacity and 125 PSI pressure rating, it's perfect for commercial or mid-sized institutional heating applications needing reliable thermal expansion management.
-
Space-Saving Vertical Design
Vertical configuration allows for easier installation in tight mechanical rooms while maintaining performance and code compliance.
-
Low Maintenance, High Reliability
Factory pre-charged and sealed—requires minimal upkeep when properly sized and installed. Non-serviceable diaphragm means fewer failure points over time.
-
Smart Value for Performance
Offers a balanced solution between full acceptance and limited acceptance tanks—great choice when moderate expansion volume is expected without overspending.

Maintenance Tips
-
Check air pre-charge annually – Shut off system, drain tank, and verify air pressure matches system fill pressure.
-
Inspect diaphragm integrity – If water exits the air valve or tank won’t hold pressure, the diaphragm may be compromised.
-
Remove air from piping – Bleed system air regularly to prevent pressure imbalance and tank failure.
-
Examine tank exterior – Look for rust, leaks, or damage; ensure the tank is properly supported and aligned.
-
Test safety controls – Confirm relief valves, gauges, and controls operate within rated pressure (up to 125 psi).
-
Monitor temperature – Keep system temperature within manufacturer-recommended limits to avoid stress on components.
-
Log maintenance checks – Track pressure readings, issues, and service dates for preventative care.
