Figure 18: Injection and Bypass Hose Connection
The inlet connection of the check valve/ injector
fitting uses a 1/2” NPT female thread.
Foam Concentrate Injection Hose
Connect a hose from the foam pump inject port
to the inlet of the check valve injector fitting.
(See Figure 18:
“Injection and Bypass Hose
Connection”)
The hose and fittings from the INJECT port to the
check valve injector fitting should have minimum
1/2” (13 mm) outside diameter and be rated at 500
PSI (34 BAR) working pressure (Aeroquip 2580-10
or equal).
Bypass Hose Connection
A bypass valve is mounted on the discharge of the
foam pump. The bypass handle must be accessible
by the pump operator during normal operations.
The bypass is a 3-way directional valve. Determine
which port is the INJECT port and which port is the
BYPASS. (See Figure 18:
“Injection and Bypass
Hose
Connection”)
Bypass hose connections are 1/2”. Hose fittings
compatible with all foam concentrates must be
provided. The hose from the BYPASS port is
plumbed to the atmosphere.
This hose is used for calibrating the foam pump,
pumping the concentrate into a container to empty
the foam tank or to assist in priming of the foam
pump. The hose from the BYPASS port must be
long enough to reach a container outside the truck.
