The water pump is a machine that transforms electrical energy into hydraulic power by transmitting it to water. It is this energy that causes the movement of the water itself. Each pump is made up of two main elements: the hydraulic part and the electric motor. The support is used to fix the pump to the base. Based on these characteristics, water pumps can be used to lift water from a lower level to a higher level by pushing and are used both for civil and domestic use as well as for industrial use.

Flow and power of the pump

But what do the flow and power of a water pump indicate? The flow rate of the pump is the volume of water, expressed in liters or cubic meters, moved by the pump itself. To raise a water flow, the pump must perform a lifting effort that requires power, ie the energy transmitted by a motor. The choice of the pump depends fundamentally on several factors, such as: the flow rate, the prevalence, the type of liquid to be pumped, since, for example, corrosive liquids require special pumps, and the available energy, important for the choice of engine organ.

Types of water pumps

Depending on the fluid, pressure, temperature or type of system, water pumps can be classified as: kinetic, volumetric and special. The kinetic pumps are the most used and, thanks to their centrifugal force, the liquid increases its kinetic energy which immediately becomes pressure energy. Volumetric pumps move constant volumes of water and are divided into alternatives and rotary presses. In this type of water pump the flow does not depend on the head, but on the amount of cycles performed in a unit of time. The special pumps are all those that do not fall into the other two previous categories but have special functions and meet specific needs.

Our pumping systems for water, at fixed or variable speed, are made to meet any need and can be used both for domestic and industrial use. Less consumption of water, noiselessness, safety, protection, reliability and resistance are the main advantages guaranteed by us at Fourgroup.
