Designed for ultimate safety and reliability, the SK series is a versatile single-stage liquid ring pump. Its unique isothermal compression process minimizes risk, making it the ideal choice for handling flammable or explosive gases across chemical, pharmaceutical, and metallurgical industries
Core Specifications:
Max Air Flow: Up to 120 m³/min
Ultimate Vacuum: -0.097 MPa
Operation: Dual-functionality as both a vacuum pump and compressor
Safety: Isothermal compression for explosion-proof reliability
The SK Series water ring vacuum pump and compressor, manufactured by Jinan Golden Bridge Precision Machinery Co., Ltd, is a single-stage solution designed for high-efficiency gas handling
Isothermal Compression : During operation, the gas compression process happens at a constant temperature, significantly reducing the risk of heat-related hazards
Explosion-Proof Safety : Due to its isothermal nature, this series is highly reliable for handling flammable and explosive gases, making its application more extensive than standard pumps
Dual Functionality : Operates efficiently both as a vacuum pump for drawing gases and as a compressor for industrial systems
Simple & Robust Design: Engineered for long-term industrial use with minimal maintenance requirements.
The SK series is widely used in processes requiring stable gas compression, especially in:
Chemical and Pharmaceutical processing.
Petrochemical industries for explosive gas handling.
General industrial vacuum systems.
Note: Performance indicators are obtained under conditions of 60mmHg atmospheric pressure, 15℃ water temperature, and 20℃ air temperature
