inch NPT threaded connection on the Hale
mini manifold, a pipe tee or a 1 inch NPT
weld fitting installed in the discharge piping
of the fire pump (see figure 2-17). The inlet
connection of the check valve/injector
fitting has ½ inch NPT female threads.
FOAM CONCENTRATE INJECTION HOSE
Connect hose from the foam pump inject
port (see figure 2-18) to the inlet of the
check valve injector fitting. The hose and
fittings from the INJECT port to the check
valve injector fitting should have minimum
½ inch (13 mm) inside diameter and be
rated at 500 PSI (34 BAR) working pressure
(Aeroquip 2580-10 or equal).
BYPASS HOSE CONNECTION
A bypass port is provided on the discharge
side of the Hale ADT or a 1/4 turn bypass
valve is mounted on the discharge of the
foam pump when the ADT option is not
installed. The bypass handle shall be
accessible by the pump operator during
normal operations.
The bypass valve is a 3-way directional
valve that selects where the output of the
foam pump will go. Determine which port is
the INJECT port (see figure 2-18) and which
port is the BYPASS port. The INJECT port is
identified on the bypass valve placard.
Look at the ports as you move the handle,
the flow should go from the center port to
each of the other ports. The bypass port on
the ADT is identified by a label above the
port.
Bypass hose connections are ½ inch NPT
threads. Hose fittings compatible with all
foam concentrates to be used must be
provided. The hose from the BYPASS port is
plumbed to the atmosphere and should not
receive high pressures. This hose is used for
calibrating the foam pump, pumping the
concentrate into a container to empty the
