Water-sealed vacuum pump (made of stainless steel) for the chemical industry

Water-sealed vacuum pump (made of stainless steel) for the chemical industry

Stainless steel (equivalent to SUS316) water-sealed vacuum pump suitable for corrosive gases.

In chemical processes, various gases containing corrosive substances are suctioned. The gas contact section uses stainless steel (equivalent to SUS316), which significantly outperforms regular iron in terms of corrosion resistance, making it a water-sealed vacuum pump. ◆ It has numerous achievements in applications such as distillation, drying, and reactions. ◆ The gas contact section is made of high-grade SCS14 (SUS316) stainless steel, allowing for the suction of corrosive gases. ◆ It is also ideal for exhausting powders, condensable gases, and flammable gases. ◆ The shaft sealing section can be equipped with either gland packing or mechanical seals. ◆ Material changes for O-rings and mechanical seals are also possible. ◆ Since it uses a general-purpose motor, explosion-proof types can also be installed.

Water-sealed vacuum pump SB series

Water-sealed vacuum pump SB series

Instead of oil, water is used for vacuum sealing, lubrication of rotating parts, and cooling of sliding parts.

The water-sealed pump consists of a circular casing and an impeller, with the impeller mounted in an eccentric position relative to the casing. When an appropriate amount of sealing water is added to the casing and the impeller is rotated, as shown in the diagram, the mass of the sealing water forms a concentric ring along the inner wall of the casing due to centrifugal force. By utilizing the change in volume of the space enclosed by the inner wall of this sealing water ring and the blades of the impeller as the impeller rotates, the actions of suction, compression, and exhaust are continuously performed through the suction and exhaust ports provided on the side wall or the inner wall of the impeller. Furthermore, efficient exhaust is achieved through high-speed rotation. Additionally, the sealing water serves as a seal to ensure that the gas being drawn in is always exhausted.
