Large PE underground chamber with adjustable height and flexible connections
The GreenLife 900-liter underground chamber is a robust and versatile chamber solution for underground technical applications. With its large usable volume, it offers ample space for pipes, connections, or technical components and can be used as a distribution, inspection, pump, or drainage chamber, depending on the application.
Made of low-density polyethylene (PE-LLD), the underground chamber is durable, resilient, and designed for long-term use in the ground. The monolithic, seamless construction ensures a stable and leak-proof chamber design. The height, which can be customized to fit specific needs, is particularly practical: The shaft can be shortened by up to 350 mm to adapt to the specific ground level. The included child-safe, walkable cover in the form of a slip-on lid protects the shaft and keeps it accessible for inspection, maintenance, or future adjustments.
The product is delivered by a freight carrier. Please note the delivery process.

Material & Quality
The underground manhole is made of low-density polyethylene (PE-LLD). The material is corrosion-resistant and suitable for long-term use underground. The manhole is manufactured using a rotational sintering process. This results in a monolithic, seamless, and dimensionally stable construction.
The material used is 100% recyclable. Further information on GreenLife and sustainability can be found here.
Notes
Before installation, the building site, groundwater level, soil permeability, and potential loads should be checked.
Please follow the installation instructions in full before installation, connection, and commissioning. In the event of improper installation or failure to follow the installation instructions, warranty or guarantee claims may be limited if a detected defect is attributable to faulty installation.
The warranty for underground chambers is 15 years. Further information can be found in the warranty certificates: DE | EN.

The TPV 200A is the version with a float switch—this provides dry-run protection. Applications:mobile drainagedomestic drainagerainwater drainagedrainage of flooded basementscirculating pond water or oxygenation for fish pondsWater features and waterfallsWastewater drainage from shafts, pits, tanks, and cisternsSolid particles in the wastewater should not exceed 19 millimeters in size. Functionality / Performance: This pump conveys wastewater using vortex impellers. The motor is continuously cooled by the medium being transported, which significantly reduces the motor’s operating temperature. This pump model features an integrated thermal protection switch: The wastewater pump stops as soon as an overload occurs—the motor restarts automatically after the pump has cooled down. The TPV 200A has a maximum flow rate of 140 liters per minute, a maximum head of 7 meters, and builds up a pressure of up to 0.7 bar. The power consumption (P1) is 0.31 kW. Quality: The TPV-200 series is made of high-quality plastic. The bearings and mechanical seal are designed for a long service life and guarantee continuous operation. The pump is very easy to clean and maintain thanks to its simple disassembly. The pump has a low weight of 5.1 kg. With protection class IP 68, the wastewater pump is dust- and watertight. Conclusion: The reliable and durable TPV 200A transfer pump is suitable for transporting contaminated water and wastewater containing solids with a particle size of up to 19 millimeters. Additional features & notes: Larger particles—with a particle size exceeding 19 millimeters—will cause the suction strainer to clog: Failure to observe this will reduce the pump’s service life or cause it to malfunction. The pump must not be used for seawater, flammable, corrosive, explosive, or hazardous liquids. The maximum temperature of the medium to be pumped must not exceed 40°C. Maintenance and Installation Instructions: The pump is maintenance-free and must be installed in a frost-proof location. When used in above-ground tanks, it must be drained in winter and stored in a frost-proof location. Please follow the installation and operating instructions.
