Stationary Pumping

What is stationary pumping in ARFF vehicles? How does it work?

Stationary pumping is similar to the function of a municipal apparatus. The vehicle is parked and stationary. Water can be discharged from the tank or from a draft or hydrant. Discharge can occur through regulated discharges (crash mode) or un-regulated discharges when the truck is configured for a structural panel.

What is the difference between stationary pumping and pump and roll functions?

Stationary pumping is a simpler operational state. Pump and roll adds the complexity of supporting full fire pump discharge capability while using power from the drivetrain to also power the vehicle’s drive. The vehicle’s engine is operated at the required output for the firefighting operation.

Are both functions critical in ARFF emergency scenarios?

Yes, depending on the scenario. If the vehicle is configured with the structural panel it can operate like a municipal apparatus for a fire in the terminal or other airport or adjacent structures. For an airplane crash scenario, it could be necessary to pump water for a long duration depending on the incident.

What are the differences in stationary pumping on a Striker® Volterra™ electric ARFF?

For the Striker Volterra EV versus a conventional ARFF truck, there is an advantage that the vehicle can reduce some noise and fuel consumption on the fire scene because the Striker Volterra electric ARFF allows the firefighter to operate the engine at a more optimal range while pumping and shut down the engine when there is not an active pumping scene.

The Striker Volterra EV can pump at full capacity as long as the incident requires. At no time does the state of charge (SOC) of the battery limit the pump output.

Are there any other safety benefits? 

The Striker Volterra electric ARFF has the capability to pump water at full capacity as long as required regardless of SOC or system state.

How does Command Zone support stationary pumping on the Striker® Volterra™ electric ARFF?

Command Zone automatically manages the vehicle’s powertrain and firefighting systems to simplify operations. It manages all safety interlocks and operator notifications to ensure safe and consistent pumping operations in all scenarios.

Are there any specifics/stats on stationary pumping with the Striker® Volterra™ electric ARFF related to reduced emissions? 

The pumping system on the Striker Volterra EV can reduce emissions by utilizing an optional pressure governed system which optimizes the power required to run the water pump.
