Underground external hydrant SMART, DN80, PN16, installation depth Rd=1500mm, height H=1225mm, single shut-off, body: GJS-spherical graphite cast iron AF0654

Underground fire hydrant – a reliable water intake point

The SMART underground external hydrant is a solid and functional solution designed for use in water supply networks and fire protection systems. It enables efficient and safe water intake, and its construction ensures long-lasting and trouble-free operation. Made of high-quality spheroidal graphite cast iron, this hydrant is characterized by corrosion and mechanical damage resistance.

Construction and application

The SMART DN80 hydrant with a single shut-off valve has been designed with ease of installation and maintenance in mind. Its construction allows for self-draining after closing, which minimizes the risk of water freezing in winter. The use of high-quality seals ensures tightness and reliable operation for a long time. This is an ideal solution for both professional installers and end-users looking for a reliable water intake point in water supply and fire protection systems. Use in water supply networks guarantees access to drinking water or other non-aggressive liquids, not containing solid particles.

Key features and benefits

• Durability and resistance: The body made of spheroidal graphite cast iron (GJS) provides high resistance to loads and corrosion, which translates into a long service life.
• Self-draining: The self-draining function after closing protects against water freezing at low temperatures and facilitates maintenance.
• Easy maintenance: The ability to replace the seal without disassembling the hydrant significantly reduces downtime during servicing.
• Compliance with standards: The hydrant meets the requirements of PN-EN 14339, PN-EN 1074-6 and Regulation 305/2011, which guarantees its safety and reliability. It has CPR, CNBOP and PZH certificates.
• Anti-corrosion protection: Electrostatic epoxy coating with a thickness of min. 250 μm provides effective protection against corrosion, even in harsh environmental conditions.
• High tightness: The use of appropriate seals guarantees the tightness of connections and prevents water leaks.
• Mechanical resistance: Withstands a MOT torque of 105Nm and a mST twisting torque of 250Nm, ensuring stable operation even under high loads.

The embedding depth Rd=1500mm and height H=1225mm allow for flexible adaptation of the hydrant to various terrain and installation conditions. The nominal pressure PN16 ensures safe and efficient operation in standard water supply systems.
