Bladder Vessel

India’s first bladder vessel for sewage-pumping surge protection — no compressors, no instrument piping, effective against positive and negative surge.

Smart Protection. Engineered Reliability.

Bladder Type Surge Vessels are globally recognized for their effectiveness in mitigating both positive and negative pressure surges—ensuring system integrity, operational stability, and long-term asset protection.

Engineered for Performance

Designed to respond instantly to transient conditions such as pump trips and sudden flow variations, bladder vessels offer:

  • Rapid absorption and release of hydraulic energy
  • Complete separation of air and water, preventing air dissolution
  • Stable and consistent pressure control without auxiliary systems

A pre-determined air charge—based on detailed surge analysis—ensures optimal performance across all operating scenarios.

Design Criteria & Sizing Philosophy

Accurate sizing and configuration are critical to achieving effective surge protection. The design of a bladder surge vessel is based on detailed transient analysis and project-specific parameters, including:

  • Pipeline profile and hydraulic characteristics
  • Pump operating conditions and inertia
  • Maximum and minimum allowable system pressures
  • Transient scenarios (e.g., power failure, valve closure)
  • Required surge mitigation performance

The vessel volume, pre-charge pressure, and operating range are optimized through simulation of worst-case conditions to ensure:

  • Effective surge absorption
  • Prevention of vacuum and column separation
  • Smooth system recovery to steady state

This methodology delivers an optimal balance between performance, safety, and cost-efficiency.
