Overview:
The 2SK/SK vacuum pump is a liquid ring vacuum pump designed to handle air and gases that are slightly corrosive, insoluble in water, and contain minimal solid particles. This makes it ideal for various industrial applications where precision and reliability are essential.
The pump operates by using water as a sealant. As the water rotates at high speed within the pump casing, it forms a closed cavity that helps remove air from the suction side, creating a vacuum effect. This mechanism ensures efficient and consistent performance.
Pumps with a double-stage design offer higher vacuum levels, faster pumping speeds, compact structures, and reliable operation. These features make them easy to operate and maintain, which is particularly beneficial for continuous industrial processes.
This type of vacuum pump is widely used in industries such as food processing, textiles, pharmaceuticals, and chemicals. It is also suitable for applications like dipping, drying, and other manufacturing processes that require controlled vacuum environments.
