Ground tank 4700 liters

Product information " Ground tank 4700 liters"

4,700-Liter Underground Tank – A Sturdy Cistern for Underground Rainwater Storage

Large-capacity, durable, and ready for installation: The GreenLIfe underground tank with a 4,700-liter capacity is a reliable solution for the underground storage and use of rainwater in the home and garden. The cistern impresses with its robust design, flexible connection options, and durable construction. Rainwater is ideal for garden irrigation, cleaning tasks, or household applications where drinking water is not required. Depending on your requirements, the cistern is available with the accessories of your choice, pre-installed at the factory. Choose between an inlet flow regulator, a tank-mounted filter, or the Biovitor—a biological, low-maintenance rainwater filter with an integrated inlet flow regulator.

Use our rainwater calculator to determine the appropriate system size for effective rainwater harvesting.

Free shipping within Germany (mainland) – delivered to the curb. Please note our delivery instructions.

Sustainability

The tank is made of durable, fully recyclable polyethylene (PE). Some of the material used comes from our own recycling program. The durable construction saves raw materials and enables environmentally friendly use for decades. The product is fully recyclable.

The material used is environmentally friendly and chemically inert—it has no effect on the quality of the stored water. The production and recycling of plastic containers are relatively resource-efficient and support a responsible, future-oriented circular economy.

Notes

For round tanks, the installation pit is generally dug deeper rather than wider. If groundwater or perched water is present, appropriate protective measures are required (see installation instructions). Alternatively, we recommend the use of flat tanks. 

Please follow the installation instructions :
Read the instructions carefully and in their entirety before installation, connection, and commissioning, and observe all safety instructions. This is the only way to ensure safe and proper operation. Improper installation or failure to follow the instructions may void warranty and guarantee claims, particularly if the defect is attributable to faulty installation.

Specifications at a glance:Max. Delivery rate/flow rate: 100 l/min (6.0 m³/h)Max. Head: 45 m / Pressure: 4.5 barConnection sizes: 1" (inch) F (female thread)Power cord length: 15 mSuitable for: Rainwater harvesting, via side intake: floating extraction of clean water from below the water surfaceMax. immersion depth: 12 mHigh-performance submersible pressure pump for versatile applications Our automatic GreenLife GAP X120 submersible pressure pump is a modern, powerful, and reliable submersible pressure pump. It handles large flow rates with ease and is suitable for a wide range of applications, such as water supply and drainage tasks in clear water. The pump automatically regulates the water flow based on the user’s water demand. Examples of applications:  Extraction of rainwater from rainwater systems, tanks, and cisternsUse of clear water inside or outside a buildingIrrigation of a lawn or gardenOperation of sprinklers or sprayers (on average, three sprinklers can be operated simultaneously)Draining or pumping water, for example from poolsDomestic water supply Operation / Performance: The pump is fully submersible and is immersed in the water. The maximum immersion depth is 12 meters. The pump automatically controls water delivery when the line to the consumer is open (faucet open). When the consumer is closed, the pump switches to standby mode. The pump is then in start/stop mode and maintains pressure in the line. When the consumer is opened again, the pump restarts and delivers water.  The GAP X120 has a maximum flow rate of 100 liters per minute and a maximum head of 45 meters. This extremely high-pressure pump, with a maximum of 4.5 bar, enables effortless and effective irrigation. The power consumption (P1) is 1.15 kW. A built-in thermal motor protection prevents overload and ensures automatic restart after cooling down. Optionally, a pump base with side suction can be mounted for floating intake. This allows clean water to be drawn from below the water surface, not from the bottom. Quality: The use of stainless steel and high-quality plastic ensures a long service life. An integrated dry-run protection shuts off the pump in case of water shortage. A practical handle makes transporting the pump a breeze. With an IP 68 protection rating, the pump is dust- and waterproof. Conclusion: With the GAP X120 submersible pressure pump, you are purchasing a modern, automatic pump that switches on and off automatically according to water demand, features dry-run protection and thermal motor protection, and is suitable for both side and floating suction. Additional Features & Notes: Do not pump saltwater, wastewater, corrosive, highly flammable, or explosive substances (e.g., gasoline, kerosene, nitro thinner), oils such as heating oil and vegetable oils, or food! The water temperature must not exceed 35°C. An integrated, easy-to-clean stainless steel suction filter provides optimal protection against debris.Please note that (as described in the installation and operating instructions) this is a clear water pump that must only pump clean water—ideally pre-filtered with the Biovitor—to remain fully functional.  You also have the option of using the pump base if the pump is placed on a surface rather than suspended (see installation instructions). Maintenance and Installation Instructions: If there is a risk of frost, drain the pump and store it in a frost-free location. Please follow the installation and operating instructions.
