Featuring a food-safe, replaceable EPDM membrane and a max operating pressure of 5.4 bar, it ensures hygienic, efficient pressure management. Built to UNI-EN standards with integrated Schrader valve control, this tank offers professional-grade reliability and easy maintenance for millennial homeowners who demand both performance and peace of mind. ## Description Replacement 50-litre 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 stainless-steel pressure vessel (type 50 LVS) will be delivered including the EPDM rubber membrane. The vessel is designed for a maximum pressure of 5.4 bar and will be delivered for a vertical positioning. The vessel is checked for tightness with up to 5.4 bar water pressure by the producer. It has a 32.89–33.25-mm (1β€³) pump connector. The pressure vessel additionally has an integrated valve (Schrader valve/car tyre valve) to regulate the counter-pressure in the space between tank and membrane. These vessels are made of quality-steel sheets and are welded according to UNI-EN standards and equipped with a heat and ageing resistant EPDM rubber membrane. The membrane can easily be exchanged. About the pre-charge in the pressurised vessel: The pre-charge pressure should be set approximately 0.1–0.2 bar lower than the switch-on pressure of the pump and has to be checked regularly. Any failure of observance may cause damage on the EPDM rubber diaphragm of the pressure vessel. A more accurate calculation results from the formula β€œswitch-on pressure of the pump x 0.9.” Example: Switch-on pressure of the pressure switch of the domestic waterworks is set to 1.5 bar: 1.5 bar x 0.9 = 1.35 bar. This means that the pressure can be set from 1.3–1.4 bar. Important: The pressure of the vessel should only be inflated or deflated after the pressure to the water system has been released beforehand. Attention: It is necessary to have released the air and water pressure before opening of the pressure vessel! ## Features - Advantages of the expansion vessels - Pressue vessels can be used for all types of water. - The water only comes into contact with the membrane. - Easily replace the membrane, EPDM is suitable for drinking water. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004BEJA5W | | Batteries Required? | No | | Batteries included? | No | | Best Sellers Rank | 190,173 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 23 in Hydraulic Tanks & Reservoirs | | Colour | Grey | | Customer Reviews | 4.6 4.6 out of 5 stars (58) | | Date First Available | 14 Dec. 2016 | | Guaranteed software updates until | unknown | | Item Package Quantity | 1 | | Item Weight | 6.34 kg | | Item model number | 50643 | | Manufacturer | WilTec | | Material | stainless steel 304 | | Part Number | 50643 | | Power Source | Solar Powered | | Product Dimensions | 36.8 x 36.8 x 72.5 cm; 6.34 kg | | Style | Vertical, 50 L | | Usage | Domestic water systems, garden, solar systems, pressure maintenance | ## Product Details - **Brand:** WilTec - **Colour:** Grey - **Material:** Stainless Steel - **Style:** Diaphragm - **Power source:** Solar Powered - **Item weight:** 7.22 kg - **Manufacturer:** WilTec ## Images ![Wiltec Stainless Steel Expansion Tank 50 litres, Vertical Diaphragm Tank for Domestic waterworks and Pressure Booster Systems with EPDM Diaphragm - Image 1](https://m.media-amazon.com/images/I/61e1u5Z3k-L.jpg) ![Wiltec Stainless Steel Expansion Tank 50 litres, Vertical Diaphragm Tank for Domestic waterworks and Pressure Booster Systems with EPDM Diaphragm - Image 2](https://m.media-amazon.com/images/I/31NXZdIJ9SL.jpg) ![Wiltec Stainless Steel Expansion Tank 50 litres, Vertical Diaphragm Tank for Domestic waterworks and Pressure Booster Systems with EPDM Diaphragm - Image 3](https://m.media-amazon.com/images/I/51Rfjl-sCzL.jpg) ![Wiltec Stainless Steel Expansion Tank 50 litres, Vertical Diaphragm Tank for Domestic waterworks and Pressure Booster Systems with EPDM Diaphragm - Image 4](https://m.media-amazon.com/images/I/41k2sycqGZL.jpg) ![Wiltec Stainless Steel Expansion Tank 50 litres, Vertical Diaphragm Tank for Domestic waterworks and Pressure Booster Systems with EPDM Diaphragm - Image 5](https://m.media-amazon.com/images/I/41TOgJfFjCL.jpg) ## Available Options This product comes in different **Style** options. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/127754830-wiltec-stainless-steel-expansion-tank-50-litres-vertical-diaphragm-tank](https://www.desertcart.sn/products/127754830-wiltec-stainless-steel-expansion-tank-50-litres-vertical-diaphragm-tank) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-10-09*
