Underground external hydrant SMART, DN80, PN16, installation depth Rd=1250mm, height H=975mm, single shut-off, body: GJS-spherical graphite cast iron AF0653

Underground fire hydrant – reliable protection for water supply and fire protection networks

This underground external hydrant of the SMART type, with a nominal diameter of DN80 and a pressure of PN16, is a solid solution designed for water intake in both water supply and fire protection networks. Made of durable spheroidal graphite cast iron (GJS), it guarantees long-lasting and trouble-free operation in demanding conditions. An installation depth of 1250 mm (Rd) and a height of 975 mm (H) ensure optimal adaptation to various installations.

The hydrant is characterized by a single shut-off, which simplifies operation and maintenance. The hydrant design enables automatic drainage after complete closure, minimizing the risk of water freezing in winter. This is an important solution to prevent damage to internal components and ensure readiness for action in any situation.

Construction and application

The hydrant body made of spheroidal graphite cast iron (GJS) provides high resistance to corrosion and mechanical damage. This material is widely used in water and sewage infrastructure elements due to its durability and reliability. The hydrant is ideal for installation in places exposed to external loads, such as public areas, parking lots or access roads.

Thanks to its design, the hydrant allows for easy seal replacement without the need to disassemble the entire structure – this significantly reduces downtime during servicing and lowers operating costs. This is particularly important for companies involved in maintaining water infrastructure and for installers who value work efficiency.

Key features and benefits

• Durable material: The body made of spheroidal graphite cast iron (GJS) provides long-term protection against corrosion and mechanical damage.
• Automatic drainage: Eliminates the risk of water freezing inside the hydrant, ensuring reliable operation throughout the year.
• Easy maintenance: The ability to replace the seal without disassembly facilitates and speeds up service work.
• Compliance with standards: Meets the requirements of PN-EN 14339 and PN-EN 1074-6 standards, which guarantees safety and reliability of use.
• Optimal installation depth: Rd=1250mm provides stability and protection against external damage.
• High efficiency: Ensures effective water intake in emergency situations or during water supply network maintenance work.
• Single shut-off: Simplified operation and easy control of water flow.
