Description of the liquid ring vacuum pump
A liquid ring vacuum pump is a rotary displacement pump in which an eccentrically mounted rotor with fixed blades pushes a liquid against the wall of the stator (housing). The liquid takes the form of a ring concentric to the stator and forms together with the rotor blades several spaces with changing volumes. The pumps can be manufactured conventionally as well as hermetically sealed with magnetic drive or canned motor drive. The leak tightness of these pumps is particularly important when it comes to pumping highly toxic, carcinogenic or radioactive gases and / or vapours where leakage of operating liquid is unacceptable. The main field of application is in the chemical industry and in process engineering for the extraction and compression of dry and above all moist process vapours.

Description of the Package Unit
Compact, ready-to-connect vacuum systems have proven to be particularly advantageous for research, planning and production. All components, such as vacuum pump / compressor, liquid separator, heat exchanger, gas ejector, valves, fittings, operating and supply lines, etc. housed in a space-saving package unit are easy to operate and maintain. When using sealless vacuum pumps / compressors, these systems are hermetically sealed. The tight ring liquid circuit ensures completely leak-free operation; therefore, no operating liquid can reach either the atmosphere or the disposal facilities. Operating liquid and cooling liquid are in separate circuits to ensure that the cooling liquid is not subject to contamination by process gas components. Aggressive, toxic, foul-smelling gases and vapours can be neutralised using a suitable operating liquid in the ring liquid circuit. Condensable intake mixtures, such as solvent vapours, are condensed through the installation of condensers and immission coolers in the package unit allowing cost-saving recovery of solvent. The hermetically sealed package unit is, therefore, a modern, perfect solution to problems in modern vacuum and process technology characterised by maximum environmental friendliness and cost-effectiveness.

Description of the magnetically coupled pump
Magnetically coupled pumps are a combination of conventional pump hydraulics with a permanent-magnetic drive system and a three-phase motor. This system uses the attraction and repulsion forces between permanent magnets in both coupling halves for contactless and slip-free torque transmission. Between the two coupling halves equipped with magnets is the can separating the product space from the surroundings. The hermetic leak tightness of the magnetically coupled pumps is ensured by a single-acting safety casing. Magnetically coupled pumps are used particularly for toxic, odour-intensive or otherwise hazardous pumped media as the can shields the medium hermetically from the surroundings.

Canned motor pumps to API 685 for reliable and economical use in the petrochemical industry
In refineries and petrochemical plants, centrifugal pumps are among the most common machines. Great importance is attached to their operational reliability and functional efficiency. In view of the difficulties and especially the costs associated with the maintenance of mechanical seals, plant designers and operators have increasingly recognised the advantages of the canned motor pump.
HERMETIC canned motor pump type CNPF 100x25x350
In practice, it has been found that hermetic pumps are generally less susceptible to repairs than conventional chemical pumps with mechanical seals and thus have a longer service life. As such, in addition to absolute leak tightness and high reliability, hermetic pumps offer the further advantage of minimal maintenance combined with high availability. API 685, which was introduced in the year 2000, is a specification that standardises the use of sealless centrifugal pumps in refineries and the petrochemical industry: API 685 - Sealless Centrifugal Pumps for Petroleum, Heavy Duty Chemical and Gas Industry Services.

Requirements for pump technology
Canned motor pumps in accordance with API 685 are used wherever no leakage is allowed and the highest demands are placed on reliability and availability; especially when conveying toxic, explosive and generally environmentally harmful media.

Carbon steel bearings are characterized by low price, the use of bearing requirements are not too high. Hardness, wear resistance, life and so on are worse than conventional bearing steel bearings.
Carbon steel bearing performance description:
First, carbon steel bearings in terms of service life. Their service life is very different, the service life of bearing steel is long, many garbage bearings are carbon steel bearings, mainly hardness and wear resistance are not as good as bearing steel bearings.
Second, in wear resistance. Low carbon steel only in the surface carburizing surface quenching, and not all quenched. Many low-grade carbon steel bearings on the market are not hardened at all, and their wear resistance is very poor.
Third, in the process and use effect. Bearing use effect is related to the use of the environment, not to say that carbon steel bearings are not good, it depends on which machinery to use, because some do not need high-grade, with carbon steel bearings is appropriate. Of course, Luo Steel is better but the cost is much higher. The standard bearing steel is Gcr15.
Fourth, in bearing materials and performance. For example, the bearing ring and the rolling body should repeatedly withstand high contact pressure, and carry out rolling contact with sliding, while maintaining high precision rotation. Therefore, whether the material and performance of bearing ring, rolling body and cage meet the following requirements: high elastic limit; High rolling fatigue strength; To have a high hardness; Good wear resistance; Good toughness against impact load; Good dimensional stability. In addition, but also good processing. It has been proved that bearing steel has the properties required above, but carbon steel bearings cannot be guaranteed.
Fifth, it is not that the advantages of carbon steel bearings are not good enough for bearing steel to be available, it depends on where to use. Carbon steel bearing noise, life is very short, the pressure is very small, but can be used in hardness, limit speed is relatively small.
Surface strengthening technology can be classified into five categories: surface deformation strengthening, surface heat treatment strengthening, chemical heat treatment strengthening, surface metallurgy strengthening and surface film strengthening according to the physical and chemical process of surface strengthening technology.
