Above-ground external hydrant HN3 DN80 H=2150mm, PN16, GJS-ductile iron, double shut-off - mushroom valve, stainless steel column 11.080.550.1500.2

Outdoor Hydrant – Reliable Fire Protection and Water Access

The above-ground outdoor hydrant HN3 DN80 is a key element of water supply and fire protection infrastructure. It serves for reliable water intake for both municipal purposes and in the event of a fire hazard. The construction made of spheroidal graphite cast iron (GJS) guarantees durability and corrosion resistance, and the double closure – mushroom and stainless steel column – ensures safety and tightness. This model, with a height of 2150 mm and a nominal pressure of PN16, is designed for effective operation in demanding conditions.

Solid Construction and High-Quality Materials

The HN3 hydrant is characterized by a solid construction based on spheroidal graphite cast iron (EN-GJS 500-7), which ensures long-term operation even in difficult environmental conditions. The use of stainless steel in the column and vulcanized sealing mushroom further increases resistance to corrosion and mechanical damage. All hydrant elements are protected with an anti-corrosion powder coating (epoxy + polyester), which extends its lifespan and minimizes maintenance costs. Thanks to this, the hydrant retains its properties for a long time, regardless of the prevailing weather conditions.

Functionality and Safety of Use

The hydrant's design is designed with ease of use and maintenance in mind. Automatic drainage after closing prevents water from freezing inside, which is particularly important in winter. The ability to replace the gasket without disassembling the hydrant significantly simplifies service work and minimizes downtime. Additionally, the rotating flange allows you to adjust the position of the hydrant to the specifics of the installation, and the reflector increases its visibility in the dark, improving safety. The hydrant's performance is 10 dm³/s at a pressure of 0.2 MPa, ensuring quick access to the necessary amount of water in emergency situations.
