4. Gardena PTFE sealing tape
The GARDENA PTFE sealing tape is ideal for sealing all threads that do not have a rubber seal or an O-ring. For decades, quality, durability, and continuous innovation have been a top priority. As a leading brand for high-quality pump products for drainage, irrigation, and home use, GARDENA brings efficiency to homes and gardens. GARDENA pumps make everyday life easier and promote resource-saving living. Whether it's flooded basements, pools, ponds, or construction pits, the drainage pumps thoroughly remove water depending on the application. Clear water submersible pumps are used for transferring and draining clean to slightly dirty water. In contrast, dirty water submersible pumps can handle water with dirt particles up to 38 mm in diameter. Those who need both functions can choose the dirty and clear water submersible pumps that combine these features. GARDENA also enables alternative water use around the garden and home, allowing gardens to be irrigated with water from alternative sources. The rain barrel pump utilizes rainwater for garden irrigation, while submersible pressure pumps water directly from wells or cisterns. The quiet garden pumps provide cost-effective water supply. The home and garden automation systems ensure automatic irrigation both indoors and outdoors. At home, alternative water resources can also be used instead of the conventional supply, allowing water from wells and cisterns to be used for toilet flushing, washing machines, or watering plants. This is made possible by the home waterworks, automatic submersible pressure pumps, and home and garden automation systems.
