Operations

Pump Panel gauges

Power transfer from engine to pump

1. Auxiliary engine driven

2. Power-take-off (PTO)

3. Cross-mounted engine

4. Front mounted

5. Mid-ship transfer drive

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.

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

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.

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.
