Fire hose delivery DN52, length 20m flat-folding WV-52-20-ŁA, for motor pumps and centrifugal pumps, inner lining PVC, aluminum coupling S-WM52-20-V-A

Universal delivery hose for submersible and centrifugal pumps

This flat-folding fire hose with a diameter of 52 mm and a length of 20 meters is a reliable solution for both professional rescue services and individual users who need an efficient hose for pumping water. Designed to work with submersible and centrifugal pumps, it is suitable for firefighting operations, drainage, as well as agricultural and industrial applications.

Construction and materials

The hose is made of high-quality materials, guaranteeing its durability and reliability. The inner layer of PVC provides a smooth surface, minimizing pressure loss of the flowing liquid and facilitating cleaning. The outer braid made of polyester yarn provides resistance to abrasion, UV radiation and flexibility in a wide temperature range – from -30°C to +80°C. Aluminum quick-release couplings of the STORZ 52 type allow for quick and safe installation without the use of additional tools. This combination of materials translates into a long service life of the hose even with intensive use.

Application and user features

This hose finds wide application in many areas:

• Fire protection: ideal for creating extinguishing lines using submersible and centrifugal pumps.
• Drainage: effective pumping of water from flooded areas, basements or excavations.
• Agriculture and horticulture: transport of water for irrigation of crops or liquid fertilizers.
• Industry: supplying cooling systems or delivering technological water.

A key advantage of this hose is its flat construction, which makes it easy to roll up and store, saving valuable space. Light weight (4.7 kg) makes it easy to transport and deploy the line by one person. The hose meets the requirements of PN-EN 14540 and ISO 1746 standards, confirming its high quality and safety of use – it has a CNBOP-PIB approval certificate. The working pressure of 1.5 MPa ensures safe operation with most medium-pressure pumps available, and the test pressure of 2.25 MPa guarantees the tightness and strength of the structure. Additionally, a high margin of safety provided by the bursting pressure (≥ 4.5 MPa) minimizes the risk of failure in critical situations.
