SAFETY

IMPORTANT NOTICE: Before attempting installation and maintenance of the Hale SPV

read and follow all safety precautions listed below. The warnings and cautions listed are
necessary for the safe installation or maintenance of the Hale SPV. When developing
departmental apparatus maintenance procedures make sure the warnings and cautions
are incorporated as written.

WARNING: Parts under spring tension can
become projectiles and cause serious
injury. When removing or installing these
parts make sure they are restrained and
spring tension is released slowly.

WARNING: Disconnect or turn-off master
battery switch prior to service of the Hale
SPV electrical components. Make sure
there is no power at the primer solenoid
before starting service procedures.

WARNING: Any electrical system has the
potential to cause sparks during installation,
service or repair. Take care to eliminate
explosive or hazardous environments during
installation, service or repair.

WARNING: Check all hoses for weak or
worn conditions after each use. Ensure that
all connections and fittings are tight and
secure.

WARNING: Use only pipe, hose, and fittings
from the priming pump vacuum connection
to the Hale SPV vacuum connection rated
for 29 in (737 mm) Hg vacuum.

CAUTION: Make sure the Hale SPV is
located higher than the pump body
allowing water to drain from the vacuum
hose.

DESCRIPTION

The Hale Semi-Automatic Priming Valve
(Hale SPV) (shown in figure 1) is a
diaphragm operated type valve that opens
using the vacuum generated by the
priming pump. The Hale SPV mounts
directly to the priming connection of a Hale
midship pump. Additionally, a universal
adapter that bolts to an installer supplied
bracket is available to permit use of the
Hale SPV on booster and volute type
pumps. The installer must also supply hose
connections from the adapter to the pump
priming connection. The Hale SPV operates
from the vacuum generated by the priming
pump when the momentary contact push­button located on the pump operator
panel is depressed. The Hale SPV conforms
to NFPA requirements for priming time and
hydrostatic test when bolted to Hale
midship type pumps. Each valve is factory
tested to 24 in (610 mm) hg vacuum and
600 PSIG (41 BAR).

When used on a midship fire pump, the
valve mounts to the pump body with two
studs and nuts, standard strainer and seal

ring. Mounted on the midship fire pump, in
close proximity to the priming pump, only a
short length of 3/4 inch (19 mm) ID vacuum
hose connects the Hale SPV to the priming
pump, eliminating potential leak points in
the priming hose. The short length of hose
also reduces the volume that the priming
pump must evacuate allowing faster
priming time and longer primer life. The
priming pump motor operates by a sealed
momentary contact push-button located
on the pump operator panel of the
apparatus. There are NO hose connections
at the pump operator panel thus saving
valuable space.

Depressing and holding the PRIME push­button will energize the priming pump
motor creating a vacuum in the 3/4 inch (19
mm) ID hose. As sufficient vacuum is
created the diaphragm will depress the
spring allowing the priming valve to open.
Once the Hale SPV opens, the priming
pump creates a vacuum in the main pump
body, priming the main pump. Once
primed, as indicated by water discharging

to the ground from the priming pump
outlet, the push-button is released. Once
push-button is released, the priming pump
stops running allowing the Hale SPV to close
for normal pump operation.

The Hale SPV is available from the factory in four different configurations. A description of
the different configurations follows.

Hale SPV Retrofit kit: Kit contains the components necessary for installing the Hale SPV on

a midship fire pump with Hale PVG installed. The kit contains a Hale SPV Valve assembly,
Panel Placard, Push-button Switch and Installation Manual.

Hale SPV Universal Mount Installation Kit: Kit contains the components necessary for

installing the Hale SPV on a volute type or booster pump. The kit contains a Hale SPV Valve
assembly, Universal Mounting Adapter, Panel Placard, Push-button Switch and Installation
Manual.

Hale SPV Mounted on Midship Pump: This available option on new midship fire pumps has

the Hale SPV mounted to the priming flange connection on the midship pump body.
Components that are included with this option and shipped with the midship pump are
the Push-button Switch, Panel Placard and Installation Manual. When completing the
apparatus installation of the Hale SPV with this option the priming pump must be mounted
on the apparatus and vacuum hose connected in addition to the push-button switch and
panel placard being installed on the operator panel.

Hale SPV and Primer Mounted on Midship Pump: This available option on new midship fire

pumps has the Hale SPV mounted to the priming flange connection on the midship pump
body and the priming pump mounted to the pump gearbox. When this option is ordered
the vacuum hose is connected from the Hale SPV to the priming pump. Components that
are included with this option and shipped with the midship pump are the Push-button
Switch, Panel Placard and Installation Manual. When completing the apparatus
installation of the Hale SPV with this option the push-button switch and panel placard must
be installed on the operator panel.
