Membrane Hydrophore Tanks – ZBOS 10 bar – Internally Coated
Membrane Hydrophore Tanks – ZBOS 10 bar are designed for storing water used to supply residential and utility buildings from private water sources for domestic or industrial purposes. When paired with self-priming or submersible pumps, they form complete hydropneumatic systems. Each tank contains a bag-style membrane made of EPDM rubber. The tanks are protected against corrosion with a coating, and both the interior and exterior are powder-coated. The flexible membrane separates the water and air systems, eliminating the need for continuous air replenishment during operation. The top head of the tank is equipped with a pressure gauge, air vent, and a handle for easy positioning.
Advantages of ZBOS 10 bar Tanks:
- Interior and exterior powder-coated finish,
- Maintenance-free operation,
- Quick and easy installation,
- Longer tank lifespan (water is contained within the membrane),
- High operating pressure,






All Hydrophor Tanks of the Type
ZBOS / ZBOL / ZBOS 10 bar
are also coated on the inside. This provide additional protection for the tank, extending lifespan as well as that of the membrane.

A diaphragm tank has a rubber membrane that separates water from air, making it practically maintenance-free. Additionally, ZBOS/ZBOL/ZBOS 10 bar diaphragm tanks are coated on the inside as well.
A galvanized tank stores water in direct contact with steel, with an air cushion above the water level. It requires periodic air replenishment.
