portable fire pump capable of delivering 275 liters per minute (LPM) with a single delivery outlet

Flow Rate: 275 liters per minute (LPM) –

This indicates the volume of water the pump can deliver per minute.
Engine Type: Typically, portable fire pumps are powered by either gasoline engines or diesel engines.
The engine should be chosen based on factors like fuel availability, ease of maintenance, and environmental considerations.

The pump should be a centrifugal pump, which is commonly used in firefighting applications due to its ability to efficiently move water at high flow rates.

Engine Power- The engine should provide sufficient power to drive the pump and maintain the desired flow rate. The power output is usually measured in horsepower (HP) or kilowatts (kW).

Suction Port: The pump should have a suction port to draw water from a water source such as a lake, river, or static water container.
The size and type of suction port (e.g., threaded or quick-connect) should be specified.

Delivery Outlet: The pump should have at least one delivery outlet for attaching hoses and nozzles. The outlet size is typically measured in inches and should match the diameter of the hoses and nozzles being used.

Construction Material: The pump casing and internal components should be made of durable materials such as aluminum or stainless steel to withstand the rigors of firefighting operations and resist corrosion.

Weight and Portability: Since it’s a portable fire pump, its weight and size should be manageable for transportation and deployment by firefighters.

Considerations like handles or carrying straps may also be included for ease of transport.
Optional Features
Depending on the manufacturer and specific requirements, the pump may include additional features such as a pressure gauge, throttle control, priming system, spark arrestor, and low oil shutdown to enhance performance and safety.
