Backflow Preventer
Hydrant Meter with Backflow Preventer
Hand Hydrotest Pump
Reduced pressure principle backflow preventer is designed to give maximum protection
against backflow caused by either back-pressure or back-siphonage from a cross-connection
wherein a contaminant hazard exists (i.e. a
health hazard
), or a pollutant hazard exists (i.e. a
non-hazard). The assembly is composed of two spring-loaded poppet type check valves and a
mechanically independent, hydraulically dependent pressure differential relief valve. Three of
the testcocks are mounted at the top to assure easy access during repair and maintenance
when unit is installed in tight places.
You can create a Fire Hydrant Backflow Preventer by using a
RSMSA25F20T
and a
DMH2025F
.
Suitable for supply pressure up to 175 psig and water temperatures from
33° F
to
180° F
.
The backflow preventer meets the requirements of the following standards:
USC’s FCCC & HR Manual, Sec. 10, ASSE 1015, AWWA C-510 and CSA B64.4. .
Working pressure:
175 PSI
