Frequently Asked Questions

A Hydropneumatic System (HPN System) is a water pressure boosting system that combines hydraulic (water) pressure with pneumatic (air) pressure to maintain consistent and efficient water supply, especially where water demand fluctuates.

The system uses a pump and a pressure tank that contains compressed air and water separated by a bladder. Water is pumped into the tank and stored under pressure. When water is drawn from the system, the compressed air pushes water out, reducing frequent pump starts and delivering a steady flow.

Key benefits include:

  • Constant water pressure at all outlets. 
  • Energy savings by minimizing frequent pump operation. 
  • Reduced pump wear and longer equipment life. 
  • Compact installation without the need for elevated storage tanks.

They are commonly used in:

  • Residential buildings and apartment complexes. 
  • Commercial buildings like offices and hotels. 
  • Industrial facilities with variable water demand. 
  • Municipal water distribution systems.

Yes. These systems can be designed for different flow capacities, pressure requirements, and applications depending on the site’s specific water supply needs.
