Submerged pump

The hydraulic pumps are machines that take care of the pumping function of liquids, in general it is, however, water. There are manual, electric or pedal hydraulic pumps. The electric one, of course, is the one that manages to guarantee the greatest movement of liquids both horizontally and upwards. If the fluids are at a certain depth, the ideal device to be able to pump them correctly is a submerged pump. For the correct choice of the correct device, two main characteristics must be taken into consideration: the flow rate and the head. The flow rate is the quantity of liquids that a pump is able to move in a given time. The prevalence, instead, indicates the maximum height that the fluid can reach once it is pushed by the device. Usually increasing the flow reduces the prevalence accordingly.

Features of submersible pumps

Submersible pumps are electrical devices that require the activation of a suitable float. In fact as soon as the liquid reaches a certain level, the float is able to activate the pump which then starts the movement. Once activated, the device is able to transform the electrical energy into kinetic energy, moving the fluid correctly. The impeller inside the machine is able to increase the fluid pressure, thus managing to push it upwards. The motor that supplies the power necessary for pumping the liquid must necessarily have particular characteristics, above all as regards insulation, since the device is submerged. There are different types of submersible pumps depending on use and needs.

Types of submersible pumps

Depending on the use, there can be many submerged pumps, some manage to handle black water, others are used for pumping wells, some for emptying flooded rooms. The one for black water is a particular type of device, given the liquids it must treat. Very often a sewage pump is also supplied with a shredder that is able to prevent the occurrence of blocks that could be caused by solid waste. The submersible pumps for wells can be used both for pumping water from a water table to a tank and for transporting water from a tank to the surface. A 12 Volt pump, on the other hand, is a small device that serves to empty flooded rooms, or to empty the bottom of boats and rafts.

Problems with submersible pumps

The major problems that can be found in the use of these electrical devices could concern above all the sizing of the device. In fact it is essential, for the correct choice of the electrical device, to perfectly calculate the flow rate and the prevalence necessary for it to be used correctly. For an adequate installation of a submersible pump, it is necessary to take into consideration the place where it will be positioned, because depending on the device some precautions must be taken into consideration. In the case of a pressure pump, there are no particular requirements, which are essential if it is an electric one, since the connections must be made, as well as properly isolating every part in which the current flows. It is very important to periodically check the float to ensure perfect device operation.
