Freeflow underground hydrant "height adjustable"

The height adjustable freeflow underground hydrant features a telescopic medium pipe of stainless steel and a telescopic operating unit. Thus the underground hydrant can be adapted to the level of the road and/or of the surrounding terrain even when installed. Depending on the version, it can be adjusted between 300 to 550 mm. The medium pipe is locked via a gripping mechanism, with the telescopic operating tube being safely held via the coupling plate.

Analogous to the standard version of the freeflow underground hydrant shutting off is effected via a shut-off blade of stainless steel.

Q = 153 m³/h at 1 bar pressure difference
Min. cross section: 70 mm
Outlet: BAIO®, flange or PE
Opening/closing: 15 revolutions
Drain-off system:

For hydrants with BAIO® spigot end outlet the dirt cover and locking ring (see supplementary products) shall be used.
