Overview

The SKA series vacuum pump is suitable for extracting gases and water vapor, with a suction pressure of 33mbar absolute pressure (97% vacuum degree). When the vacuum pump works for a long time at a suction pressure below 80mbar, a cavitation protection tube should be connected to protect the pump. If equipped with an atmospheric injector, the suction pressure can reach 10mbar, and the injector can be directly installed on the vacuum pump. When used as a compressor, its pressure Z can reach up to 0.26MPa (absolute pressure).

SKA series vacuum pumpSuitable for extracting gas and water vapor, the suction pressure reaches 33mbar absolute pressure (97% vacuum degree). When the vacuum pump works for a long time under the suction pressure below 80mbar, a gas corrosion protection pipe should be connected to protect the pump. If equipped with an atmospheric injector, the suction pressure can reach 10mbar, and the injector can be directly installed on the vacuum pump. When used as a compressor, its pressure can reach up to 0.26MPa (absolute pressure).

Water ring vacuum pumps and compressors are widely used in industries such as petrochemicals, pharmaceuticals, food, and sugar manufacturing. Due to the isothermal compression process of gases during operation, they are less prone to danger when compressing and suctioning flammable and explosive gases, making them more widely used.

Structure and Characteristics

The coaxial direct connection design of the pump saves space and is easy to install.

Adopting mechanical seals as standard configuration eliminates leaks and makes maintenance easy.

△ Smooth operation, noise can be as low as 62 decibels

Unified corrosion-resistant design, bronze impeller improves the pump's corrosion resistance, while stainless steel material is more suitable for more demanding applications

The flexible exhaust port design of △ * ensures that SKA operates efficiently within its performance range without excessive compression.
