Centrifugal canned pump

The centrifugal canned pump is a special centrifugal pump that plays an important and unique role in many fields.

1. Structural features

Shielded motor

One of the core components of the centrifugal canned pump is the shielded motor. The stator and rotor of the motor are completely enclosed by the shielding sleeve. This design completely isolates the motor from the medium being transported, preventing the medium from leaking to the outside world, and also preventing foreign substances from entering the motor and affecting its operation. The shielding sleeve is generally made of highly corrosion-resistant and high-permeability materials, such as stainless steel, to ensure good sealing and motor performance.

Centrifugal impeller

The impeller adopts a centrifugal design. The impeller is usually made of high-quality metal materials with special blade shapes. When the impeller rotates, the centrifugal force is used to transfer energy to the medium, so that the medium generates pressure and flows. The efficient design of the impeller ensures that the pump can achieve a large flow and head with low energy consumption during operation.

No shaft seal design

Due to the use of a shielded motor, the centrifugal canned pump does not have the shaft seal structure of a traditional centrifugal pump. The shaft seal is the part of the traditional centrifugal pump that is prone to leakage problems, and the shaft seal-free design fundamentally eliminates this hidden danger, making the centrifugal canned pump particularly suitable for conveying some special media with corrosive, flammable, explosive, toxic and harmful properties.

2. Performance advantages

Good sealing

In the chemical, pharmaceutical and other industries, the requirements for preventing media leakage are extremely high. With its unique shielded motor and shaft seal-free design, the centrifugal canned pump can achieve a nearly zero leakage operation effect. This not only protects the surrounding environment, but also ensures the safety of the production process and product quality.

Stable and reliable operation

Its structure is compact, and the coordination between parts is carefully designed. The shielded motor runs smoothly and the centrifugal force of the impeller is stable, so that the pump can maintain a stable flow and pressure output during long-term operation. And because there is no problem of shaft seal wear, the maintenance frequency is reduced and the overall reliability of the equipment is improved.

Strong corrosion resistance

Since it is often used to convey corrosive media, the centrifugal canned pump fully considers this demand in material selection. In addition to the corrosion-resistant materials of the shielding sleeve, the pump body, impeller and other parts can also use suitable corrosion-resistant materials according to different media, such as various stainless steel alloys, engineering plastics, etc., thereby extending the service life of the pump.

3. Application fields

Chemical industry

Used to transport various corrosive chemical raw materials and intermediate products such as acids, alkalis, and salt solutions. For example, in the production process of sulfuric acid, the centrifugal canned pump can stably transport sulfuric acid from one process to another.

Pharmaceutical industry

Transport various liquid medicines, pharmaceutical raw materials, etc. Due to its good sealing performance, it can prevent the medicines from being contaminated and ensure the quality of the medicines.

Nuclear energy industry

In the cooling system of the nuclear reactor, the centrifugal canned pump can safely and reliably transport coolants to ensure the normal operation of the nuclear reactor.

With its unique structure and excellent performance, the centrifugal canned pump has become an indispensable fluid transportation equipment in many industries with high requirements for sealing, stability and corrosion resistance.
