Fire hose delivery DN52, length 20m flat-folding HV-52/20-ŁA, for fire hydrants, internal lining PVC, aluminum coupling S-WH52-20-V-A

Fire hose for hydrants – reliability and safety

This flat-folded delivery hose, with a diameter of DN52 and a length of 20 meters, is a key element of every fire protection system. Designed for use with hydrants, it provides quick and effective access to water in case of a threat. Made of high-quality materials, it guarantees reliability and durability, and its compact form facilitates storage and transport.

Construction and user parameters

The hose is characterized by a solid construction, based on a round-woven braid made of durable polyester yarn. The inner liner made of PVC provides a smooth surface, minimizing pressure losses and facilitating water flow. Aluminum couplings guarantee tightness and a durable connection to the hydrant or other installation elements. This makes the hose resistant to mechanical damage and weather conditions.

The hose design ensures adequate water flow for extinguishing fires – the inner diameter is 52 mm (with a tolerance of +/- 1.5 mm). The length of 20 meters is optimal for most hydrant applications. The safe working pressure in standard fire protection systems is 1.5 MPa, and the high resistance to sudden pressure surges guarantees a bursting pressure of 4.5 MPa. The ability to use in a wide range of ambient temperatures (-30°C to +60°C) and the relatively low weight of the hose with couplings (5.2 kg) facilitate maneuvering during fire fighting operations.

Application and compliance with standards

This hose is used in public buildings, industrial plants, warehouses and anywhere where effective fire protection is required. It is ideal for quickly distributing water from hydrants during fire fighting or fire drills. It meets the requirements of PN-EN 14540:2005(U) standard, which confirms its high quality and safety of use. Additionally, the innovative hose-to-coupling connection technology (protected by intellectual property right UPRP No. 62999) eliminates the risk of the hose fraying at the end of the coupling sleeve, improving ergonomics and aesthetics of use.
