BIMEX Hydropneumatic Surge Vessel, Expansion Tank, or Blaader Type is expertly designed to manage pressure surges with an internal rubber bladder. This innovative approach ensures the vessel’s elasticity effectively pushes water back into the system following a pump trip. A critical aspect of this system’s efficiency is the accurate calculation of the pre-charge pressure, which is vital for optimal performance.

By preventing contact between compressed air and water, the vessel eliminates the risk of air dissolution into the water. This design feature negates the need for a permanent regulation system, such as compressors, thereby simplifying the system and reducing maintenance requirements.

Once the vessel is correctly pre-charged and stimulated, it operates automatically. The vessel depressurizes as needed and refills with return waves until it naturally reaches a steady-state balance. This automatic operation ensures consistent performance and reliability in surge control.

The internal bladder is typically made from high-tensile rubber, which may include reinforcements and is available in various materials such as Neoprene, Nitrile (Buna-N), Food Grade Butyl, or Hypalon rubber. The bladder is designed to expand to fit the entire vessel and is securely attached with a flange at the top, tailored to the specific vessel details provided by the client.

This advanced design not only ensures efficient surge control but also extends the lifespan of the vessel and associated system components. Trust BIMEX to deliver high-quality, reliable solutions for your surge control needs, backed by our commitment to innovation and excellence.
