The need to move fluids and in particular water on the surface or at different heights has very ancient origins. The solution was the invention of the hydraulic pump, a closed device with a suction and a delivery duct, equipped with mechanical moving parts activated by a force. Electricity and modern technologies have led to the creation of different types of electric pumps whose design and construction is optimized for the specific purpose of use.
An electric pump is a device driven by an electric motor that is used to move, lift or collect liquid materials.
An electric pump can be of the industrial or domestic type. In particular this second type is optimized for the purpose of operation.
There are various types of pumps and the choice is mainly dictated by the type of use that will be made. Among the requirements for the choice of the pump it is necessary to consider the type of liquid to be moved, the power that determines the quantity (Q) to be pumped in a given time and determines the flow rate (liters per minute or cubic meters per hour), the height (H) in the column to which it is able to carry the liquid and determines the head (meters).
The centrifugal pump.
The electric pump commonly called "centrifugal" is generally used to give greater pressure to the water; it is generally used to bring or withdraw water from a tank, to feed an autoclave, for pressure washing systems, for filling tanks and swimming pools, for irrigation as well as for all the needs related to simple movement flat or pressurized. It is generally installed at a height similar to that of the withdrawal point and dispensing points.
The submersible pump.
The submersible electric pump is generally used for the extraction and pumping from the subsoil and at the same time gives outlet pressure, in order to feed a column of water vertically. It is equipped with a watertight motor for which it is installed immersed in a well even at considerable depths, therefore in the vicinity of the withdrawal point and at a height lower than that of the dispensing points.
The self-priming pump.
It is an electric pump that combines the function of a centrifugal pump and a submersible pump because it is generally used for extraction and pumping from the subsoil and at the same time confers outlet pressure, in order to feed a column of water vertically. Generally it is installed on the surface near the well from which it will take the water through a pipe and therefore at a height higher than the point of withdrawal; it is also capable of feeding a column of water vertically.
The submersible pump.
The submersible pump is generally used for extraction and pumping from tanks or similar. One of the most common uses is the emptying of garages and cellars following flooding or for emptying cesspools. The submersible pump is equipped with a watertight motor for which it is generally used by immersing it directly in the liquid to be pumped, it is also capable of pushing the sewage vertically. The submersible electric pump can be set up for the suction of clean water (electric pump for clear water) or for dirty water (electric pump for dirty water and electric pump for sewage).
One of the aspects to consider when choosing an electric pump, especially for a centrifugal pump or a self-priming pump, is the noise which is directly influenced by the number of impellers it is equipped with; the greater the number of impellers of the pump, the lower the speed at which they must turn and consequently its noise level will be lower. Another important aspect are the construction materials of the impellers and the pump body; for the former the best is stainless steel (although thanks to modern technologies, technopolymers capable of high resistance and long life are being developed), for the latter, cast iron is generally used, which is particularly resistant to water pressures.
