Liquid Ring Vacuum Pump System for Solvent Recovery Equipment
System Overview
ur liquid ring vacuum system is fully integrated into the solvent recovery unit without the need for an external liquid tank. This design allows the system to maintain a stable vacuum while continuously discharging recovered solvent.
By significantly lowering the solvent boiling point—by over 50%—this system is particularly suitable for recovering high-boiling-point solvents, expanding the range of solvents that can be efficiently processed.
The system operates without relying on compressed air or interrupting recovery for tank drainage, which improves operational efficiency and enhances overall system stability.
Key Features
High Vacuum Capability
Achieves a maximum vacuum of 99 kPa, suitable for reduced-pressure distillation of high-boiling-point solvents.
No Vacuum Tank Capacity Limitations
Maintains vacuum while continuously discharging recovered solvent, avoiding downtime or interruptions due to vacuum tank capacity constraints.
Corrosion Resistance
Key components are made of chemically resistant materials, compatible with various industrial solvents.
Oil-Free Operation
Vacuum is generated by a liquid ring formed from the working fluid (e.g., solvent) inside the pump chamber, eliminating the need for oil lubrication and preventing solvent contamination.
No Compressed Air Required
Does not rely on compressed air during operation, reducing energy consumption and system complexity.
Low Noise Operation
Operates at relatively low noise levels, helping to improve the working environment.
High Energy Efficiency
Offers higher power conversion efficiency compared to traditional pneumatic vacuum pumps.
Low Maintenance Requirements
Simple structure with long regular maintenance intervals and stable operation.
Applications
The liquid ring vacuum system is designed for use in industrial solvent recovery processes that require consistent vacuum performance, especially when handling high-boiling-point or viscous solvents. It is suitable for:
- Solvent recycling and distillation equipment
- High-boiling-point solvent recovery operations
- Continuous solvent separation processes
- Recovery of inks, paints, adhesives, and resin-based solvents
- Chemical, pharmaceutical, and electronics manufacturing
- Systems requiring oil-free, low-noise vacuum operation
