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.

GreenLife Biovitor DN 100 for flat tanks

Biological Filter for Rainwater HarvestingAre you looking for a low-maintenance rainwater filter that purifies your water without chemicals and achieves a high yield of top-quality rainwater? Then you’re in good hands with the GreenLife Biovitor. The Biovitor contains no wear parts, so you can count on maintenance intervals of up to ten years. We developed the GreenLife Biovitor to eliminate the need for chemical additives and high-maintenance filters in rainwater purification. Unlike conventional designs, the Biovitor uses the same natural processes for biological self-purification as our local waterways. This ensures consistently high-quality rainwater in your rainwater harvesting system  How our patented BIOVITOR biological rainwater filter works The Biovitor purifies your rainwater 100% chemical-free based on the natural decomposition process of organic material, such as leaf debris. It consists of two optimally sized chambers that guarantee highly efficient biological processes.Here’s how it works: The rainwater enters the gutter through the gutter grate (or other leaf guards) and eventually flows through the downspout into the Biovitor, which is located in the tank or cistern. The first chamber contains marble gravel, which can slightly raise the pH of the water to neutralize slightly acidic rain, if necessary. This also slightly mineralizes the rainwater. From here, the pre-treated water flows into the second chamber, which is equipped with bio-active media. Here, the remaining organic components are decomposed and broken down by oxygen and natural microorganisms in the water. Inorganic components settle at the bottom. The clear and clean water then slowly enters the rainwater tank to prevent turbulence. The Biovitor acts as an inlet stabilizer and achieves 100% rainwater yield, as there are no losses due to contaminated rainwater filters. Applications for the BIOVITOR Rainwater Filter Our biological rainwater filter improves the quality of your rainwater through biological processes. It is suitable for all cisterns and can be retrofitted to almost all rainwater systems. Additionally, the Biovitor is highly suitable for a rainwater system with subsequent infiltration; an additional filter before infiltration is then not necessary. Connection options: DN 100 (dₐ = 110) Connectable area: 170 m² Scope of delivery GreenLife BIOVITOR DN 100 Biological sedimentation filter with DN 100 connection (dₐ = 110): Rainwater inlet (inlet pipe DN 100)Biovitor tank with 1st and 2nd Biovitor chambers and overflows into the tankMarble gravelBio-active media Maintenance and cleaning Since the system does not rely on high-maintenance filter designs or chemical additives and contains no wear parts, maintenance intervals are typically five to ten years. Cleaning of the pre-filter systems, e.g., gutter grates or other leaf-trapping technology, is essential and must be performed regularly. Additional Notes Please refer to the operating instructions for the installation, maintenance, and mounting of the Biovitor.

Aerator and vent with DN 100 emergency overflow

Vent and air release valves for safe pressure equalization & reliable emergency drainage The vent and air release valve with DN 100 emergency overflow ensures reliable air equalization in tanks, pipes, and soakaway systems and effectively protects the system against overpressure or underpressure. If the maximum water level is exceeded, for example during heavy rain, the component also acts as an emergency overflow for safe drainage. The vent is typically installed at the end of an infiltration system and is usually discreetly located outdoors, e.g., in a hedge or flower bed. To ensure that (rain)water can flow smoothly into the system, a controlled air outlet must be provided elsewhere. For this purpose, a DN 100 KG pipe is installed behind the system, which safely guides the air to the surface. The vent is the terminus of this line and is designed to reliably prevent the entry of animals. Product Features & Benefits at a Glance Pressure equalization during water withdrawal or supply – prevents damage caused by overpressure or underpressure Automatic venting and de-airing – ensures trouble-free system operation Integrated emergency overflow – protects against overfilling during heavy rain Standard DN 100 connection – compatible with common KG pipe systems Lightweight & durable – approx. 350 g, made of robust polypropylene Made in Germany – manufactured to high quality standards and DIN EN ISO 14001:2015 Typical applications Rainwater storage tanks & infiltration systems – for ventilation and emergency drainage Wastewater collection pits & infiltration systems in wastewater treatment plants – for pressure equalization and operational reliability Sustainability The product is made of durable, single-grade, and fully recyclable polypropylene. The material is long-lasting, free of harmful substances, environmentally friendly, and chemically inert – it has no impact on the environment.
