2SK Vacuum Pump

I. Product Overview

The 2SK series two-stage water ring vacuum pump utilizes a tandem dual-impeller structure. It uses water as the working fluid and generates a vacuum through impeller rotation to perform gas extraction and suction functions. This series is characterized by high vacuum levels, high pumping capacity, stable operation, a compact structure, and a long service life; it is particularly well-suited for high-vacuum applications and continuous operation.

The 2SK series is widely used in industries such as chemicals, pharmaceuticals, food processing, papermaking, electric power, mining, electronics, vacuum drying, vacuum filtration, vacuum evaporation, and vacuum packaging. It is designed to extract air and other gases that are non-corrosive, water-insoluble, and free of solid particles.

II. Product Features

1. Dual-impeller structure ensures a high ultimate vacuum, making it suitable for high-vacuum applications.

2. High pumping capacity, stable operation, low noise, and minimal vibration.

3. Compact structure with a small footprint; easy to install and maintain.

4. Uses water as the working fluid; no oil contamination during operation.

5. Suitable for continuous operation with a long service life.

6. Can be combined with a Roots vacuum pump to form a vacuum unit, thereby enhancing the system's vacuum level.
