Wiltec 50L INOX / Stainless Steel Pressure Tank Vessel Expansion Domestic Waterworks Pump EPDM-Membrane

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

This 50-liter stainless steel pressure tank (tank type 50 LVS) comes with an EPDM membrane. The tank is designed for a maximum pressure of 5.4 bar and is delivered in a vertical design. 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 (formerly 1 inch). Additionally, the pressure tank features an integrated valve (Schrader valve/automobile tire valve) to control and 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.

Regarding the pre-pressure in the membrane tank: The pre-pressure should be approximately 0.1–0.2 bar below the pump's switching 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 switching pressure x 0.9". For example: If the switching pressure on 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!.
