Power transfer from engine to pump

• Auxiliary engine driven
• Power-take-off (PTO)
• Cross-mounted engine
• Front mounted
• Mid-ship transfer drive

4
Auxiliary engine driven pump

• Uses a separate engine to drive the fire pump
• Used for specialty applications
• 1. Airport crash trucks
• 2. Portable brush pumps
• They can be mounted anywhere on the apparatus it
  will fit.

5
Relay pumping operations

• The process of using two or more pumpers to move
  water through hoselines over long distance by
  operating the pumpers in series

6
Tandem pumping operations

• A short relay operation in which the pumper
  taking water from the supply source pumps into
  the intake of the second pumper.
• The second pumper booster the pressure of the
  water even higher.
• This method is used when pressures higher than
  the capacity of a single pump are required.

7
Dual pumping operations

• An operation where a strong hydrant is used to
  supply two pumpers by connecting the pumper
  intake-to-intake.
• The second pumper receives the excess water not
  being pumped by the first pumper, which is
  directly connected to the water supply source.
