## Long description

Membrane pressure tank GRUNDFOS GT-H 35 L is designed for domestic and small commercial water systems. The 35-litre bladder tank stores pressurised water to reduce pump cycling, stabilise system pressure and provide a reserve of ready-to-use water. It connects to pumps and pressure systems via a 1" port and is suitable for boosting, circulation and pressure stabilisation in wells, booster sets or closed water circuits.
Advantages
The GRUNDFOS GT-H 35 L features a replaceable internal membrane that separates the water chamber from the air cushion, which helps maintain consistent pressure and reduces the frequency of pump start-stop cycles. Its compact, cylindrical design allows for straightforward installation in confined spaces and near existing pumps. Durable materials and attention to sealing reduce the risk of leaks and minimise maintenance needs over time.
Suitable for
 Household water supply systems to reduce pump wear and noise
 Small commercial booster sets and circulation systems
 Well water installations and shallow boreholes with booster pumps
 Systems requiring short-term reserve water and pressure stabilisation
Key specifications
 Nominal volume: 35 litres of usable water storage
 Connection size: 1" threaded inlet suitable for standard pump fittings
 Internal type: pre-charged membrane/bladder separation for air and water
 Application: potable and non-potable water systems for pressure boosting and circulation
 Typical operating pressure range: designed to support common domestic booster pressures (pre-charge pressure adjustable before commissioning)
 Installation orientation: vertical mounting recommended for optimal membrane operation
How to use
Install the GRUNDFOS GT-H 35 L on a stable, level surface close to the pump or pressure system. Connect the 1" port to the system piping using appropriate seals and fittings. Before first use, check and adjust the air pre-charge in the tank to match the pump cut-in pressure according to system design. Commission the system by slowly filling the tank and checking for leaks. Routine checks of the pre-charge pressure and visual inspection of connections help maintain performance.
Usage recommendations
Set the tank pre-charge to approximately 2 psi below the pump cut-in pressure for optimal cycling reduction. Avoid exposing the tank to freezing temperatures and protect it from direct sunlight or corrosive environments. If the membrane shows signs of wear or loss of separation between air and water, replace the membrane according to maintenance instructions to restore correct operation.
