DN25 recessed hydrant, 30m semi-rigid hose, padlock coupling, red RAL3000 color S-25-W30-P-3000

Internal fire hydrant – reliable fire protection

This recessed internal fire hydrant DN25 is a key element of fire protection equipment in public buildings, industrial plants and other facilities requiring quick access to a fire extinguishing water source. Designed for easy installation and reliable operation, it provides effective protection against the effects of fire. The set includes a 30-meter semi-rigid hose, allowing access to hard-to-reach places.

Design and application

The hydrant is designed for recessed mounting, providing an aesthetic appearance and protection against mechanical damage. Made of high-quality materials, it guarantees long-lasting and trouble-free operation. The versatility of this model allows connection to a supply installation with a diameter of 1” or 2”, offering six different connection options – from the side, from the back or from the top. The Supron 3 brass hydrant valve ensures durability and corrosion resistance. The lack of clamping bands and the use of only threaded connections facilitate installation and maintenance.

Advantages and benefits

• Versatility: The ability to connect to 1” and 2” installations and six different connection configurations make the hydrant suitable for most existing installations.
• Durability: The brass hydrant valve and the solid construction of the powder-coated steel sheet cabinet ensure long-term operation.
• Safety: Equipped with a patent lock that protects against unauthorized access to the hose and nozzle.
• Easy installation: Threaded connections eliminate the need for clamping bands, which significantly speeds up the installation process.
• Compliance with standards: The product meets the requirements of PN-EN 694 (hose) and PN-EN 671-1 (nozzle) standards, guaranteeing safety of use.
• Efficiency: Provides adequate water flow at a pressure of 0.2 to 1.2 MPa – with an equivalent diameter of 10 mm, a flow rate of up to 104 l/min is obtained at a pressure of 0.6 MPa.
• Practical solutions: The semi-rigid hose makes it easier to maneuver during fire fighting, and the hose reel with adjustable winding force ensures smooth and controlled winding.

Remember to perform regular hydrant maintenance according to the manufacturer's instructions to ensure its reliable operation when needed. Technical drawings and BIM models are also available to facilitate installation design. At a pressure of 0.2 MPa, the flow rate of the diffused stream is about 61 l/min, and the solid stream about 60 l/min; at a pressure of 0.4 MPa, respectively, about 86 l/min and 85 l/min; and at a pressure of 0.6 MPa, about 104 l/min for the diffused stream and about 103 l/min for the solid stream. The effective range of the water jet using a 30 m long hose exceeds 15 meters at a pressure of 0.2 MPa, over 18 meters at a pressure of 0.4 MPa and over 21 meters at a pressure of 0.6 MPa.
