Did you mean Jockey Pump which is a small pump connected to a fire sprinkler system and intended to maintain pressure in a fire protection piping system to an artificially high level so the operation of a single fire sprinkler will cause a drop in pressure that will be sensed by the fire pumps automatic controller, causing the fire pump to start. The Jockey Pump is essentially a portion of the fire pumps control system.

The fire pump churn test, is when an operator runs the fire pump without the flow of water
The best way to maintain and improve the efficiency of a septic system with an aerator pump is to regularly inspect and clean the pump, ensure proper ventilation, and avoid flushing harmful chemicals or materials into the system. Regular maintenance and proper usage can help extend the lifespan and effectiveness of the aerator pump in the septic system.
Not a lot. A fire fighting pump found on most fire engines is the centrifugal type. Other than the amount of water it may flow and the number of discharges it can supply, there is no difference (although I'm not sure what "ordinary centrifugal pump" refers to unless it is a trash or sump pump). Centrifugal type pumps weren't always used in the fire service, but they are the standard now because they can spin (they can pump or maintain pressure) even when there is no water actually flowing.
Tarrif Advisory Committee guidelines for pump manufacturing
The purpose of the jockey pump is to keep the water pressure in the pipes within a specific range when there's not a fire, so that the sprinklers won't go off randomly. Since pipes leak, over time, the water pressure inside them automatically goes down. The jockey pump senses this, and then fills them back up to normal pressure. If a fire happens and the pressure drops dramatically, the jockey pump won't be able to keep up, and the drop in pressure will trigger the large fire pump to start sending water. Secondarily, this pump prevents sprinkler systems from being damaged when the fire pump begins sending water. If a system does not have a jockey pump keeping it pressurized, it may have a relatively low pressure. When the fire pump starts sending highly pressurized water through the pipes, the sudden change in pressure can damage or destroy the system.
A "fire department connection" (FDC) is often required on a sprinkler or standpipe system in case the ordinary supply of water fails to provide enough pressure for any reason. That way, a fire engine's pump can be used to pressurize the system with water from other sources.

There is no such thing. The pump runs off a relay. There is a fuel pump shut off relay. If the ecm sees a fault in the system, it will shut off the pump to prevent damage or fire.
No. it is a single cock spring system. You only need to break the barrel once to cock it and fire it.
it is in the fuse block and is used to protect the fuel pump and wiring to the fuel pump from being overloaded and melting or catching fire by detecting to much current and blowing (melting) before the wire harness or pump does.
When choosing a well water pump for your house, consider factors such as the depth of your well, the water usage needs of your household, the pump's flow rate and horsepower, the pump's efficiency and durability, and whether you need additional features like a pressure tank or water filtration system.
