Expansion tank membrane for hydrophore 50–60 L, VAREM MB060S2P00000000

Replacement expansion tank membrane compatible with VAREM hydrophore tanks of 50–60 litre capacity. This elastomer bladder is designed to separate air and water inside the pressure vessel, preserving system pressure and preventing waterlogging. It is intended for use in domestic and light commercial hydrophore systems where the original membrane requires replacement due to wear, fatigue or damage.

Advantages

The membrane is made from durable elastomer material engineered for repeated flexing and long service life under normal operating pressures. Its shape and dimensions match the original component specification to ensure a proper fit and restore the tank’s ability to maintain pressure. Installation of a new membrane eliminates common issues such as frequent pump cycling and loss of pre-charge, helping the pressure vessel operate as designed.

Suitable for

• Replacement of worn or damaged internal bladders in 50–60 L VAREM hydrophore tanks
• Repair and maintenance of domestic water pressure systems
• Light commercial pressure vessel servicing where compatible with the specified tank size

Key specifications

• Compatible tank capacity: 50–60 litres
• Material: elastomer bladder (rubber-based)
• Function: internal separation of air and water to maintain pressure
• Application: hydrophore/expansion pressure vessels for potable and non-potable water systems
• Replacement type: direct-fit membrane for the corresponding VAREM model range

How to use

Drain and depressurise the hydrophore tank before disassembly. Remove the tank from service, open the tank or access the internal bladder according to the manufacturer’s service instructions, and extract the old membrane. Fit the replacement membrane ensuring correct orientation and seating on the tank collar or connection point. Reassemble the tank, restore system pressure, and set the correct pre-charge according to the hydrophore manufacturer’s recommended value. After installation, check for leaks and verify pump cycling and pressure behaviour under normal operation.

Usage recommendations

Use this membrane only where compatible with the specified 50–60 L VAREM hydrophore tanks. Confirm tank compatibility and pre-charge requirements before installation. Replace the membrane if it shows signs of cracking, deformation, or persistent loss of pre-charge, and follow local regulations for disposal of the removed component.
