Before starting talking about this subject, it is important to differentiate a fire truck from a fire engine. The first one is designed to carry the fire equipment and firefighters at the fire scene, while the second one is designed to fight structural fires, as it has incorporated a water tank. This being said, how does a firefighter extinguish the blazes with the help of hoses and the water tank?
Pressure and suction
The primary function of any pumper is to carry a water tank filled with at least 3000 liters of water or to directly suck water from external sources, such as a drop tank, a fire hydrant, a swimming pool, a lake or from the sea. There are two types of hoses, which are produced by fire truck manufacturers: suction hoses and attack hoses. The water pressure depends on the diameter of the hose and the force of the impeller water pump. Sometimes, the water pressure is so high that it requires more than one fireman to keep the hose towards the fire. There is a great risk when he is situated on the aerial platform, because he may lose the balance.

The pump is located behind the jump seat area, exactly where the fire fighter seats. An impeller driven by its own diesel engine spins inside the pump at high rate. Water that comes into the pump is hit on the inner part of the impeller and slung outward. The centrifugal force from the spinning action of the impeller creates water pressure. Later on, a valve will open to allow water to hit the center of the rotating impeller. This is the mechanism inside a pumper. This innovative machine can be found in all Volkan Fire engines, as we are an advanced and qualified fire truck producer.
