  • brass hydrant valve 25 manufactured by Supron 3
  • fire hose reel in RAL 3000 color hinged for 180°, with water axis and brake for controlling the unwind force
  • φ25 mm semi-rigid fire hose 20 m or 30 m length according to PN-EN 694, fixed connection to water axis by crimping the hose with aluminum sleeve
  • hydrant nozzle type PWh-25 according to PN-EN-671-1, fixed connection to fire hose by crimping the nozzle with aluminum sleeve
  • valve and water axis connection hose; all thread connections without hose clamps
  • hydrant cabinet insulated by material with thermal conductivity 0.0359 [W/m*K]
  • 150W heating element with thermostat, 230V
  • buckle lock
  • marking: sign “Hydrant” according to PN-EN ISO 7010:2012 + information plate according to PN-EN 671-1

Attention! The dependence of the flow rate Q on the pressure P is given by the equation: Q = K√10P, where Q is expressed in liters / minute and P in megapascals.

Possibility of implementation

52 valve with slant reduction

Hydrant can be connected to DN52 water supply due to 52 valve with slant reduction
