1 TECHNICAL DESCRIPTION
1.1 PRODUCT NAME AND FEATURES
The subject of this O&MM is:
Break-away fire hydrant with double closure
- With additional protection against flow in the form of ball valve;
placed below poppet
- With automatic water drainage activated by medium flow stoppage;
- With poppet (closure) embedded in 100% pure elastomer;
- Internal parts may be replaced without cutting off flow;
- Valve body with saddle tees may be rotated within the range from 0
o
to 360
o
.
1.2 PURPOSE
Break-away fire hydrants TYPE 8003 with double closure are intended for fire protection systems, for
chemically neutral pure water, free of impurities and for industrial systems. For use on above-ground
installations on pipelines laid horizontally below the freezing zone.
1.3 TECHNICAL SPECIFICATION
Break-away fire hydrants with closure are intended for transport of potable water and industrial
water at temperatures from +1°C to +50°C.
- Available diameters (dimensions) DN80-DN100 [mm]
- Maximum medium flow rate: - liquid up to 4 [m/s]
- driving torque at opening start and closing end are listed below:
DN [mm]
80 100
Mmax [Nm]
80 80
- equipment control: closing direction in the standard version of hydrant:
clockwise closing sense of rotation.
The closing sense of rotation can be opposite on special order.
-connection flanges are manufactured in accordance with PN-EN 1092-2:1999
with the dimensions adequate to the relevant nominal pressure of 1.6 MPa.
-Hydrant's efficiency with nominal pressure 0.2 MPa is:
10 dm
3
/s – above ground DN80
15 dm
3
/s – above ground DN100
In accordance with PN-B-02863: 1997 "Fire water supply"
-Key for controlling valves and taps PN-89/M-74088
-Design in accordance with PN-EN 14384:2009 TYPE C
-Saddle tees B 75 per DIN 14318: 1985
-Saddle tees A 110 per DIN 14319: 1985
2 STRUCTURE
2.1 HYDRANT DESIGN DESCRIPTION
The fire hydrants are made in the form of column with internal structure to enable drawing water from
pipeline and a header with saddle tees for attachment of fire hoses. In the lower part of the hydrant there is a cast-
iron valve chamber with a poppet acting as closing element and a drainage device. The chamber housing is
connected to the ball's (ball return valve) valve chamber finished with a connection flange for installing the
hydrant on the pipeline. Top part of the hydrant is a cast-iron body with outlet openings with saddle tees. The top
body also has a driving element on the end of bolt used for transferring rotational movement to the hydrant's
poppet via distance pipe. The top body of a break-away fire hydrant is connected to the underground part with

thinner bolts. Such a connection enables breakage of hydrant without damaging it and resulting water outflow.
Special flanges enable free rotation of the ground part of the hydrant from 0° to 360°. There is a special
articulation spindle inside the hydrant, in the connection area of the above ground and underground part of the
hydrant. The rotating stem is seated in a stopper with rubber sealing rings. Rotate the hydrant clockwise to close
the flow. Poppet moves during rotation of the stem and flow opens. The poppet's movement closes the water
draining device's outlet opening. When closing a hydrant, the poppet lands in the seat and the water remaining in
the hydrant's column using draining valve.
With this type of hydrant, it is possible to replace the complete internal equipment of a hydrant without cutting
off the supply thanks to a ball valve.

CLOSE OPEN
The order of operations during opening and closing of a hydrant type 8003 configured with a shutoff gate
valve.
- Starting:
1. Open the shutoff gate valve.
2. Open the hydrant.
- Stopping:
3. Close the hydrant.
4. Close the shutoff gate valve.

Caution! It is prohibited to open this type of hydrant with a closed shutoff gate valve because the poppet
sliding down must be able to push a water column in the direction opposite to the flow direction during
the first phase of its movement.
