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

This 24-liter pressure tank (tank type WPT 24L) is supplied with an EPDM membrane. The tank is designed for a maximum pressure of 5.4 bar, comes in a horizontal version with a mounting plate for a household waterworks, and is suitable for wall mounting. 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 to 33.25 mm. Additionally, the pressure tank features an integrated valve (Schrader valve/automobile tire valve) to control and regulate the counter pressure for the membrane. The hole diameter of the mounting feet is 8 mm, and the elongated holes of the pump plate are 10 mm. The pressure tank is equipped with a pump mounting plate.

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.

Regarding the pre-pressure in the membrane tank: The pre-pressure should be about 0.1 to 0.2 bar below the pump's cut-in pressure and must be checked regularly. Failure to do so may cause damage to the EPDM membrane of the pressure membrane tank. A more precise calculation can be derived from the formula "Pump cut-in pressure x 0.9". For example: If the cut-in pressure at the pressure switch of the household waterworks is set to 1.5 bar, the result is 1.5 bar x 0.9 = 1.3 to 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!.
