The 2SK series is engineered for industrial applications requiring deeper vacuum levels and high-speed performance
Core Performance:
Deeper Vacuum: Achieves significantly higher vacuum than single-stage models
2SK-P1 Jet Unit: Can be paired with an atmospheric jet pump to reach even higher vacuum levels
High Efficiency: Large pumping speeds maintained even in high vacuum regions
Robust Build: Compact structure with easy maintenance for long-term operation
The 2SK Series two-stage water ring vacuum pumps, manufactured by Jinan Golden Bridge Precision Machinery Co., Ltd, are designed to draw in air and other non-corrosive, water-insoluble gases
Thanks to its high vacuum stability, the 2SK series is widely utilized in
Pharmaceutical & Chemical: Vacuum distillation, evaporation, and solvent recovery.
Food & Beverage: Vacuum concentration and dehydration.
Metallurgy & Electronics: Vacuum smelting and impregnation processes.
Textile Industry: Vacuum drying and rehumidification.
Note: Performance indicators are obtained under standard conditions: Atmospheric pressure 60mmHg, water temperature 15℃, and air temperature 20℃
