Hydraulic Turbo Stream Requirements
HYDRAULIC REQUIREMENTS
FoamPro Hydraulic Turbo Stream systems are
provided with major components and accessories
required for installation, except for the hydraulic pump
and controls. The standard hydraulic motor is a .976
cubic inch per revolution motor. The hydraulic pump
will need to provide 7.6 GPM at a pressure of 2400
PSI for the Turbo Stream to reach full performance.
The volume should not exceed 8.2 GPM and the
pressure should not exceed 2700 PSI. Due to
differences in chassis and apparatus configurations,
the installer must provide hydraulic pump coolers,
fluids, reservoir, pipe, hoses, tubing and fittings to
satisfy installation requirements. Before beginning
system installation, read this section thoroughly
to make sure the proper components are selected.
PUMP/MOTOR BASE ASSEMBLY
The pump/motor base assembly must be mounted
in the horizontal position. The system can be run at
15 degrees on any plane to the horizontal and may
be run intermittently at 30 degrees to the horizontal
plane. The base of the system must be anchored to
a surface or structure that is ridged and of adequate
strength to withstand the vibration and stresses of
apparatus operation. The main pump has a water
drafting capability not to exceed six feet of vertical lift
and should not be subjected to an inlet pressure of
more than 3 PSI to ensure proper operation of the foam
injection system. The drawings on pages 14, 15, and 16
provide the mounting dimensions for the FoamPro High
Pressure pump/motor base assembly. Flexible hose is
required to make the hose connections to the FoamPro
High Pressure System. DO NOT hard pipe the system.
Protect the hoses and wiring to prevent chafing and
abrasion during operation of the foam system. Protect
the foam pump base unit from excessive spray and
debris. See engine manual for allowed engine operating
conditions.
LINE STRAINERS
There are two line strainers provided with the FoamPro
unit. The pump inlet line strainer has 3/4-inch NPT
female threaded ports and is to be installed on the
water inlet of the foam pump. The water supply hose
should have adequate wall stiffness to withstand the
vacuum of the pump while it is in operation [23 in. (584
mm) Hg and 50 PSI (3 BAR)].
The second strainer has 1/2-inch NPT male and 1/4-
inch NPT female-threaded ports and is to be installed
in the foam inlet before the flow meter. The foam supply
hose should be 1/4 to 3/8- inch and able to withstand
23in/Hg of vacuum and 50 psi. Clear foam supply hose
is recommended so that the operator can see the flow
of foam concentrate in the hose.
NOTE: If a pressurized water flush is incorporated, the
pressure should be limited to 100 PSI (7 BAR).
CHECK VALVES
A 3/4-inch check valve is included at pump inlet. A foam
injection check valve is incorporated in the design.
FLUSHING SYSTEM
Depending on the corrosiveness of the foam
concentrates to be used, a flushing system may be
required in the foam concentrate injection system.
Most Class A foam concentrates (per NFPA 1150) are
less corrosive and therefore may not require flushing.
It is important to flush and drain the entire system
before long periods of storage to prevent component
malfunction.
THERMAL RELIEF VALVE
A thermal relief valve is included with the system to
prevent pump overheating during unloading.
ELECTRICAL CONNECTIONS
See engine manual for detailed electrical connections only if engine is equipped with electric start.
