Which components are included in a fire pump of a sprinkler system?

In a fire pump of a sprinkler system, the components that ensure effective operation and monitoring include the pump itself, the driver which powers the pump (this could be an electric motor or a diesel engine), the controller that manages the operation of the pump (including starting and stopping the pump based on system pressure or flow demands), and the pressure gauge which allows for monitoring of the pressure within the system to ensure it is functioning properly.

This assembly is critical because the pump's primary function is to provide the necessary water flow and pressure to the sprinkler system during a fire event. The driver ensures the pump operates adequately, while the controller integrates the system for operational efficiency and safety. The pressure gauge is vital for checking that the system maintains the required pressure levels to deliver water effectively.

The other options contain components that are either not typically part of a fire pump system or mix systems together incorrectly, which would lead to confusion about their roles within a fire protection system.
