Centrifugal Pumps

Centrifugal Pumps Working Principle

Centrifugal pumps are hydraulically operated machines characterised by their ability to transmit energy to fluids (in particular to liquids) through the work of a field of centrifugal forces. Their main purpose is to transfer fluids through an increase in pressure. Centrifugal pumps can have different structures, but their operating principle and fluid dynamic characteristics are always the same.

Schematically, centrifugal pumps are formed of an impeller that rotates inside the casing.
The impeller comprises a series of blades, preferably of a radial design, which transmit kinetic energy to the fluid being pumped.
The casing is equipped with suction and discharge nozzles for the fluid being pumped. The suction nozzle has an axis that corresponds with the impeller’s rotational axis, while the discharge nozzle has a normal axis to the impeller axis, but still lying on the plane passing through the axis itself.

We provide the right pump for every application. For use in various industries such as chemical industry, environmental engineering, analysis technology, food technology, and many other fields. You can choose from a wide range of products, from different pump types and materials.

Centrifugal pumps with magnetic coupling

Centrifugal pumps with magnetic couplings are completely maintenance-free thanks to the use of exclusive static seals. In contrast to conventional centrifugal pumps with mechanical seals or shaft seals, centrifugal pumps with magnetic couplings are permanently protected against leakage. Power transmission from the motor to the pump head is done magnetically. The motor drives an outer magnet, which is passed through its rotational movement by the insulating shell of the magnetic head located inside the pump. The insulating shell located between the magnets is a barrier that safely separates the medium from the outside atmosphere.

Centrifugal pumps with shaft seal

The rotary motion and power from the engine must be transmitted to the pump impeller, without the pumped liquid leaking from the pump head. The separation between the pumped medium and environment takes place on the drive shaft. The seal may be executed as a shaft seal or mechanical seal. Shaft seals must be checked regularly for leaks. The safety and lifetime of these gaskets is extremely inferior to that of magnetic couplings.
