Hydrophores membraan 100 L MB080F2P drinkwater-expansievat

Potable water expansion vessel with 100-liter capacity, engineered for reliable pressure management in domestic and commercial water systems. Its butyl rubber membrane and robust steel construction ensure long-term performance and safety.

Advantages

The fixed diaphragm design separates water from the air cushion, preventing waterlogging and maintaining consistent pressure. The deep-drawn carbon steel shell with epoxy powder coating resists corrosion, while the galvanized steel flange adds durability. Factory pre-charged to 1.5 bar, it's ready for installation and reduces pump cycling, extending system life.
