The short length of hose also allows for a faster priming time and longer
primer life by reducing the volume that must evacuated.
The priming pump motor is push-button operated, 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 push button energizes the priming
pump motor creating a vacuum in the 3/4” (19 mm) ID hose. As sufficient
vacuum is created the diaphragm depresses the spring to OPEN the prim-
ing valve, thus creating 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 to STOP the priming
pump. The SPV then CLOSES for normal pump operation.
Configuration Options
The Hale SPV is available from the factory in four (4) different configura-
tions. A description of each follows, beginning on the next page.
Retrofit Kit Option
The retrofit kit contains the components necessary for installing the Hale
SPV on a midship fire pump. The kit contains a Hale SPV Valve assembly,
panel placard and push button switch.
Universal Mount Installation Kit Option
The Universal Mount Installation Kit contains the components necessary for
installing the Hale SPV on a volute or booster type pump. The kit contains a
Hale SPV Valve assembly, universal mounting adapter, panel placard and
push button switch.
Midship Pump Mounted Option
This option mounts the Hale SPV to the priming flange connection on a
“new” midship pump body. Components 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, the priming
pump must be mounted on the apparatus with the vacuum hose connected
in addition to the push-button switch and panel placard being installed on
the operator panel.
