Their operating principle is based on the conversion of mechanical energy into hydraulic energy by means of the centrifugal force generated by a rotating impeller.

These pumps stand out for their versatile design and wide range of applications in sectors such as water supply, chemical industry, wastewater treatment and power generation.

Over the years, centrifugal pumps have evolved in terms of their construction, shaft arrangement, number of impellers and hydraulic characteristics.

They can be classified into different types according to their suction, impeller shape and casing, thus allowing their adaptation to different operating conditions.

However, with technological advances and increasing demands for energy efficiency, sustainability and reliability, the industry has developed innovations in the design and materials of these pumps.

The most outstanding distinctive features are presented below.

A centrifugal pump is a type of hydraulic pump that uses the principle of centrifugal force to move liquids.

Its design consists of an impeller that rotates inside a casing, creating a flow of liquid.

These pumps are widely used in a variety of industrial applications, from water supply to chemical processes.

These pumps have a design that includes a volute (spiral casing) that converts the kinetic energy of the liquid into pressure.

The most outstanding distinctive features are presented below.

Diffuser pumps use a series of fixed vanes (diffusers) that convert fluid velocity into pressure.

With multiple impellers (stages) in series, these pumps can significantly increase the liquid pressure.

These pumps have an impeller with open blades, which allows solids and particles to pass through.

These pumps have an impeller with closed blades, which improves efficiency and performance.

Designed to prevent the liquid from draining completely from the impeller, these pumps are ideal for applications where cavitation is a problem.

Technological advances have improved the efficiency, durability and versatility of centrifugal pumps.
