SKA series water ring vacuum pump features and applications

1. Use and application range

SKA series vacuum pump is suitable for removing gas and water vapor, suction pressure reaches 33mbar Absolute pressure (97% vacuum) When the vacuum pump in the suction pressure below 80mbar long-term work, should be connected to the protection of the pump to protect the pump For protection, with air jets (see attached table) Suction pressure up to 10 mbar, ejector can be mounted directly on the vacuum pump. Used as a compressor, the pressure up to 0.26MPa (absolute pressure).

Water ring vacuum pumps and compressors are widely used in petrochemical, pharmaceutical, food, sugar industry and other fields, as in the process of work, the gas compression process is isothermal, so in the compression and pumping flammable gas, Not prone to danger, its application is more extensive.

2. Structure and characteristics

Pump coaxial coaxial design, space-saving, easy to install;

The mechanical seal as a standard configuration, eliminating the leak, easy maintenance;

Smooth operation, the noise can be as low as 62 dB;

A uniform corrosion-resistant design, bronze impeller to improve the corrosion resistance of the pump, stainless steel is more suitable for more demanding applications;

The unique, flexible vent design eliminates over-compression and ensures SKA is the most efficient within its performance envelope.
