Wiltec 50L Pressure Tank Vessel Expansion for Domestic Waterworks Pump EPDM-Membrane drinking water

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 50-liter pressure tank (tank type 50 LVS) is delivered to you with an EPDM membrane included. The tank is designed for a maximum pressure of 5.6 bar and is delivered in a vertical design. The manufacturer tests the container for tightness at water pressures of up to 5.6 bar.

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/car 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.

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 at regular intervals. Failure to observe this may cause 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". Example: Switching 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!.
