Applications

Water Supply and Drainage Systems: Widely used in municipal water supply pipelines, industrial water circulation systems, and sewage treatment lines to filter impurities such as sediment, rust, and particles, protecting downstream equipment like pumps, valves, and meters from wear or blockage.
Heating and Ventilation Systems: Applied in district heating networks, boiler feed water pipelines, and HVAC systems to remove debris in the water or heat transfer medium, ensuring efficient heat exchange and preventing clogging of radiators or heat exchangers.
Industrial Circulation Systems: Utilized in industrial production lines (such as chemical, metallurgical, and textile industries) for filtering cooling water, process water, or low-corrosive industrial fluids, maintaining the cleanliness of the medium and reducing equipment failure risks.
Irrigation and Agricultural Systems: Installed in agricultural irrigation pipelines to filter sand, soil particles, and organic residues, protecting sprinklers, drip irrigation emitters, and other irrigation equipment from blockage and ensuring stable water supply.
General Fluid Transport Pipelines: Suitable for various non-aggressive fluid transport scenarios (e.g., water, oil, and neutral liquids) where impurity filtration is required, serving as a pre-treatment component to enhance system reliability.

Their robust cast iron construction and compliance with German standards make them ideal for medium-pressure, moderate-temperature, and general industrial or civil applications requiring durable filtration solutions.
