Above-ground fire hydrant model N7 with traffic break-away design (Type C) - single shut-off for drinking water and neutral liquids to max. 60° C

AVK’s Multi hydrants are available with multiple configurations. The heavy duty materials with extra corrosion protection, the PUR coated disc with high memory effect and the high flow capacity ensure durability and good performance. Series 84/91 is a single shut-off hydrant with traffic break-away design. The flanges connecting the upper and lower barrel are assembled with special stainless steel bushes designed to break if something hits the hydrant. These bushes are the only spare parts to be replaced in case of a breakdown.
