Storm gate for external drainage – protection against flooding and rodents

The KARMAT ZB200 storm gate with a diameter of 200 mm is a reliable protection of the sewage system against the effects of floods, heavy rainfall or sewage backflow. The device protects rooms located on the lowest floors from flooding, and also prevents rodents and unpleasant odors from entering the building. It is a key element to ensure comfort and safety in every home, company or public utility facility.

Construction and application

The gate is designed for mounting on horizontal drain pipes, both before exiting the building and in inspection chambers. Its construction based on polypropylene (PP) ensures durability and resistance to corrosion, negative temperatures and the action of chemical compounds. Made of PP-R, the gate is resistant to sewage temperatures up to 95°C. Thanks to its automatic operation, it does not require an external power supply or frequent maintenance. Complete flap deflection ensures unhindered flow of sewage, and careful workmanship and smooth internal surface prevent sediment accumulation.
