100L Diaphragm Pressure Vessel GEKO G81522
A horizontal 100-litre diaphragm pressure vessel designed for storing potable water in systems with submersible pumps and pressure sets. The carbon steel construction with a rubber diaphragm removes the need for air top-ups and protects against internal corrosion.
Technical features
Diaphragm design
The rubber diaphragm inside the vessel separates the water from the air cushion. This keeps the pressure in the system constant, prevents the water from coming into contact with the vessel walls and removes the need for periodic air top-ups, as is the case with tanks that have no diaphragm.
Horizontal orientation
Mounted horizontally, the vessel takes up less vertical space, which makes installation easier in rooms with limited headroom, such as cellars or plant rooms. The horizontal design provides stability without the need for additional fixing.
Construction material
The body is made from carbon steel with a powder-coated finish, giving resistance to weather and moisture. Powder coating is more durable than liquid paint, which extends the service life of the vessel.
1-inch connection
A 1" thread is the standard size in pressure systems, compatible with most domestic pumps and plumbing fittings. This makes it easier to select system components and to install them without reducers.

Applications
- Pressure systems in single-family homes supplied from private wells
- Water supply systems in holiday homes and allotment plots
- Water supply for farms and livestock buildings
- Irrigation systems in gardens and greenhouses
- Operation with submersible and surface pumps
- Pressure boosting systems in water installations
- Protection against frequent pump cycling (buffer function)
How a diaphragm pressure vessel works
The rubber diaphragm divides the vessel into two chambers: water and air. As it fills, the water compresses the air cushion, increasing the pressure in the system. Once the pressure reaches the pump cut-out point, filling stops. Drawing water allows the air to expand and the pressure to drop, which starts the pump again. As a result, the pump does not run every time a tap is opened, which extends its service life.
Installation and maintenance
The vessel should be installed horizontally on a stable surface or support structure. The 1" connection is joined to the system using standard threaded fittings. Before commissioning, check the pre-charge pressure in the air chamber (typically 0.2-0.3 bar below the pump cut-in pressure) and top it up through the air valve if necessary.
Maintenance involves periodically checking the pre-charge pressure (every 6-12 months) and checking the connections for leaks. Do not exceed the maximum working pressure stated by the manufacturer. If the diaphragm is damaged, it must be replaced – this is indicated by the pump cycling frequently and water escaping from the air valve.
