    Drinking water separation stations prevent the medium from flowing back from service water lines connected behind it into the drinking water line and are used in fire extinguishing systems, sprinkler systems, laboratory water systems and in agriculture. As a manufacturer of drinking water separation stations, SPECK guarantees hygiene by separating the drinking and service water using a pre-tank, which generally has a DVGW certificate for safe connection in accordance with W 540 and is also tested by DEKRA in the area of ​​fire-fighting water systems. Our systems offer comfort with motorized ball valves, which prevent pressure surges in the lines by opening and closing as required, and can also easily comply with the specifications for flushing according to the latest DIN 1988 Part 600 with flow rates of max. 2 m/sec. In extinguishing water systems according to DIN 14462, flushing takes place once a week according to DIN 1988-600. In the case of drinking water separation stations for the water supply, this takes place at the latest every 72 hours according to VDI 6023. In both cases with safety devices according to DIN EN 1717 type AB, with a free outlet and a controlled emergency overflow to protect the drinking water, with the aim of maximum safety to guarantee. For this purpose, systems are used that are tailored to the entire system down to the smallest detail, for a long service life of your drinking water separation station. To control the system, we have developed a simple but well thought-out principle based on decades of experience. All information can easily be called up via the display. By installing standardized branded products as part of the control, it can be easily repaired anywhere in the world. That saves time and money. We guarantee a 100% final test for every drinking water separation station. All products go through a standardized testing process that is documented for our customers. This ensures that the commissioning of Speck drinking water separation stations will be a complete success.
