Above ground hydrant model N7 with breakaway design (Type C), double shut-off, for drinking water to max. 40°C
AVK 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 outstanding performance. Series 84/93 is designed with double shut-off system for a continued sealing of the hydrant during maintenance, and with breakaway design. The flanges connecting the upper and lower barrel are assembled with special stainless-steel bushes designed to break in case of collision. These bushes are the only spare parts to be replaced in case of a breakage.
