The replacement tank for use in sanitary cold/hot water systems is suitable for almost all domestic waterworks, solar and pressure maintenance systems, as well as garden pumps.

This 100-liter pressure tank (tank type 100L pressure tank) is delivered to you with an EPDM membrane included. The tank is designed for a maximum pressure of 5.4 bar and is supplied in a vertical version. The manufacturer tests the container for tightness at up to 5.4 bar water pressure.

The membrane tank has a connection size of 32.89–33.25 mm (old: 1 inch). Additionally, the pressure tank features an integrated valve (Schrader valve/automobile tire valve) to control or regulate the counterpressure for the membrane. These pressure vessels are welded from quality steel sheets according to UNI-EN standards and are equipped with a heat- and aging-resistant EPDM membrane. The EPDM membrane is easily replaceable.

About the pre-pressure in the membrane tank:
The pre-pressure should be approximately 0.1–0.2 bar below the pump's switch-on pressure and must be checked regularly. Failure to do so may result in damage to the EPDM membrane of the pressure membrane tank. A more precise calculation can be derived from the formula "Pump switch-on pressure x 0.9". Example: The switch-on pressure at the pressure switch of the domestic waterworks is set to 1.5 bar: 1.5 bar x 0.9 = 1.3–1.4 bar.

Important: The tank pressure should only be inflated or released when the pressure in the water system has been relieved. Caution: Always release air and water pressure before opening a membrane tank!.
