What is the difference between pumping in the parallel position and the
series position? (P.301) Correct Answer-When the pump transfer valve
is in the volume position, each of the impellers takes water from a
source and delivers it to the discharge.
Setting the transfer valve to series (pressure) greatly increases the
maximum pressure that may be attained. Increasing the pressure results
in a corresponding loss in volume.
Switching from volume to pressure can result in the immediate doubling
of the previous discharge pressure. This change may result in damage to
the pump and hoselines as well as injury to firefighters.
If there is any question as to the correct position for the transfer valve, it
is best to operate in parallel (volume) rather than series (pressure).
