50L INOX Pressure Tank Vessel Expansion Domestic Water EPDM-Membrane

Replacement 50-l stainless steel pressure vessel for use in sanitary cold-/hot water systems, suitable for nearly all domestic waterworks, solar- and pressure maintenance systems, and garden pumps. This pressure vessel will be delivered with incl. EPDM membrane and has a 50-l capacity. The vessel is designed for a maximum pressure of 5,4 bar and will be delivered in a horizontal position. The tank is checked for tightness with up to 5,4 bar water pressure by the producer. It has a 32,89–33,25-mm (1″) pump connector. The pressure vessel has additionally an integrated valve for inflating the space between tank and membrane. This vessel series is welded of qualitative steel sheet, according to UNI-EN-standards and is equipped with a heat- and age resistant EPDM-membrane. About Ethylene-Propylene-Diene-Monomer Rubber: This EPDM rubber belongs to the group of elastomers. This synthetic material is characterised by resistance to hot air, weathering, and ozone. The elastomer shows low gas permeability, good resistance to chemicals as well as up to 100 °C very good noise and shock energy absorption qualities. In the low temperature range, the butyl rubber remains elastic up to −70 °C. It is mainly used for air hoses and inner cores of tyres, bladders, steam hoses, and linings for tanks. Further fields of application are foils, membranes, unvulcanised sealants, and bands. About the primary pressure in the pressure vessel: The primary pressure should be set approximately 0,1–0,2 bar lower than the switch-on pressure of the pump and has to be checked at regular intervals. Any failure of observance may cause damage on the EPDM-diaphragm of the pressure vessel. A more accurate calculation results from the pump’s switch-on pressure x 0,9. Example: Switch-on 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 pressure of the vessel should only be inflated or deflated when the pressure to the water system has been released before. Attention: It is absolutely necessary to have released the air and water pressure before the opening of the pressure vessel !
