The hydrant may be perfectly adjusted to the local conditions thanks to its freely rotating upper part and the standard height adjustment in 5 cm increments.
The flange connection meets the requirements of DIN EN 1092-2. The hydrant corresponds to the standards for pillar hydrants DIN 3222, DIN 3321 and EN 14384 as well as the DVGW testing principle VP 325.
The most important elements
- operating cap, connected to the solid stem extension with a stainless steel pin
- aeration and vent valve underneath the cap
- aluminium B couplings according to DIN 14318, attached to the hydrant by a stainless steel chain
- linkage entirely made of stainless steel
- brass linkage safeguarding arrangement
- dual shut-off
Technical properties
The upper part of the pillar hydrant housing is entirely made of EN-JS 1050 ductile cast iron and enamelled on the inside. The outside of the upper part has a base enamel coating and an additional red paint finish in RAL 3001. Standpipe and standpipe cover are enamelled inside and outside.
The hydrant has two upper B outlets.
Linkage, stem and all screws are made of stainless steel. Stem nut, guide piece, support bearing and predetermined breaking coupling are made of brass.
In order to prevent the hydrant from being destroyed by impact such as from a car, the linkage is divided with a brass coupling on the progression to the upper part. This way, only the damaged elements with the predetermined breaking elements need to be replaced.
The type 504 pillar hydrant comes with a dual shut-off. An additional obturator ensures sealing when the linkage is replaced under pressure.
Because of the dual shut-off, the pipe does not need to be pressure-free. The safety clasp, however, which protects the maintenance workers, needs to remain in place until the tightness of the dual shut-off can be guaranteed.
