Upotuspumppu

Upotuspumppu, also known as a submersible pump, is a device designed to be fully submerged in the fluid it is intended to pump. These pumps are commonly used for applications such as draining flooded areas, emptying wells, removing wastewater, and circulating water in aquariums or fountains. The motor and the pump body are sealed together, preventing water from entering the motor housing and causing damage. This design allows the pump to operate efficiently underwater and also helps to cool the motor.

The principle of operation for an upotuspumppu is similar to that of other centrifugal pumps. A rotating impeller within the pump casing draws fluid into the inlet and expels it through the discharge outlet at a higher pressure. The submerged nature of the pump means that it does not require a priming process, as it is always surrounded by the fluid it is pumping. This makes them particularly convenient for automatic operation, often controlled by a float switch that activates the pump when the water level rises to a certain point and deactivates it when the level drops.

Upotuspumppuja are manufactured from various materials, including stainless steel, cast iron, and plastic, depending on the intended application and the type of fluid being pumped. They come in a range of sizes and capacities to suit different needs, from small domestic units to large industrial pumps. Safety features, such as thermal overload protection for the motor, are often incorporated into their design. Their reliability and ability to operate unattended make them a popular choice for a wide array of dewatering and fluid transfer tasks.
