Centrifugal pump advantages are rather obvious in such applications as circulation of water, ventilation systems in houses and office buildings or hotels. As a matter of fact, some of the centrifugal pumps are installed at the end user of some heating systems while some others are sold to original equipment producers who further integrate the centrifugal pumps into huge pumping systems. In most cases, the centrifugal pump is marked by a canned rotor which not only has static sealing but is also designed to minimize the pumping noise with and without automatic regulation.
At the same time, thanks to the automatic regulation of the centrifugal pumps, it is possible to adjust the centrifugal pumps pressure and flow rate to meet the actual need and save energy, which is another remarkable centrifugal pump advantages. What is more, the above mentioned type of centrifugal pump sealing is commonly used when the specific application requires that the pump is sealed completely despite the fact that the rotor and impeller are separated from the centrifugal pump stator and is surrounded by pumping fluids that are capable of lubricating the bearings and the motor. As a result, the pumping fluids around the rotor lead to less friction and thus improve the efficiency of the centrifugal pump.
Some centrifugal pump users are concerned about the possible leak flow yet there is no need to worry about this point any more thanks to the centrifugal pump advantages. In the case of traditional centrifugal pump, this kind of situation may occur in the gap between the rotating impeller and pump housing during centrifugal pump operation and the flow rate mainly depends on the design of the impeller pressure rising components. What is more, the flow will return to the impeller eye through the gap in less than a rotating circle because the centrifugal pump impeller needs to pump both the leak flow and the pumping fluids from the inlet flange to the outlet one. Therefore, to reduce the leak flow as much as possible, the centrifugal pump impeller seal should be mounted even though they come in various designs and are made from different material combinations.
This is because the centrifugal pump seal is typically turned in a direct manner in the pump housing and can be made with a range of floating seal rings or rubber rings as long as they are well suited to deal with fluids that contain such abrasive particles as sand. Last but not least, to play the centrifugal pump advantages to the fullest, centrifugal pump users not only need to choose the right impeller and reduce the leak flow, but also need to carefully consider the type and size of the centrifugal pump.
