Extinguishing water suction connections

Safety and reliability at every moment

Extinguishing water suction connections are an indispensable component for any professional fire extinguishing system. Developed in accordance with the strict DIN 14244 standards, this connection guarantees maximum reliability and efficiency in critical situations. Our products offer you the necessary safety and performance to be able to act quickly and effectively in an emergency.

Suction connections for extinguishing water can be connected to various water sources:

  • to an extinguishing water well for suction/pressure operation
  • to the suction pipes of underground extinguishing water tanks
  • to the suction pipe of an extinguishing water pond

In the normal state, the outlet side of the suction connection is closed with an A cover capsule. In an emergency, the A suction line is connected here to extract water.

In the case of an extinguishing water well for suction or pressure operation, the water level in the well can be determined by opening the dipstick nozzle.

High-quality construction for maximum durability

Robust housing

The housing of our extinguishing water suction connection is made of high-quality cast iron with spheroidal graphite. This material is characterized by exceptional stability and durability, so that the connection functions reliably even under demanding conditions.

Protective coating

An epoxy plastic coating (RAL 3000 red) provides additional protection against corrosion and mechanical damage, further increasing the service life of the product.

Standardized connections

The DN 100 flange connection complies with the DIN EN 1092-2 PN 16 standard and guarantees simple and safe integration into existing systems.

A-fixed coupling and cover capsule with chain

The extinguishing water suction connections are each equipped with an A-fixed coupling and a cover capsule including chain. These components enable a quick and uncomplicated connection, which saves valuable time in an emergency.
