Foam Pump Flush System
Dual Tank System
Flushing water must be provided to flush the system of foam concentrate
after each use. This prevents adverse reactions of some foam concentrates
should they mix together. The Hale ADT and MDT II each have provisions
for connecting flushing water to the foam concentrate injection system.
Single Tank System
The Hale MST provides a selector valve and gives the system flush capabil-
ities for NFPA compliance. A fitting provided on the Hale MST simplifies the
flushing water connection.
No Tank Option
The system installer must provide a flushing water supply to comply with
NFPA standards.
The flushing water hose must be a minimum of 1/2” (12 mm) inside diame-
ter and capable of withstanding the maximum fire pump discharge pressure,
500 PSI (34 BAR) minimum. The flush water supply should be provided
from one of the pressure taps on the discharge of the fire pump.
