DV Vacuum vacuum solutions for environmental engineering, vapor recovery, and utility applications are designed for continuous-duty industrial service.
Typical applications include VOCs recovery, waste gas handling, vacuum priming, gas extraction, condensable vapor handling, and utility vacuum service.
Solution configurations are selected according to process conditions using liquid ring vacuum pumps, dry screw vacuum pumps, and engineered vacuum systems.
Environmental and utility projects often require vacuum support for vapor recovery, waste gas extraction, vacuum priming, and related process duties under continuous operating conditions.
These applications may involve wet gases, condensable vapors, continuous-duty operation, and integrated auxiliary systems, so pump selection should consider medium compatibility, process stability, and practical site requirements.
DV Vacuum supports customers with both standard vacuum pumps and engineered system configurations matched to environmental project requirements.
Supports extraction and closed-loop condensation recovery of volatile organic compounds, using oil-free DVS-V Variable-Pitch Dry Screw Vacuum Pumps combined with downstream condensers and separators.
Suitable for applications where vacuum is used to collect, transfer, or support the treatment of process gases before downstream handling.
Used in municipal waterworks, pumping stations, and utility headers for rapid water suction and system priming, reliably handled by compact DVL Liquid Ring Vacuum Pumps.
Supports controlled extraction of process gases from tanks, pits, process vessels, and enclosed handling systems.
Applicable to moisture-laden gas streams where robust liquid ring technology like the DVL Series provides safe isothermal compression without risk of liquid damage.
Provides vacuum support for utility networks and auxiliary engineering systems operating under continuous-duty conditions.
| Product / System | Recommended Use | Key Features |
|---|---|---|
| DVL Series Liquid Ring Vacuum Pumps | Wet gas evacuation, vacuum priming, and environmental utility duties | Isothermal operation, robust tolerance for entrained liquids and water vapor, and reliable continuous service |
| DVS-V Variable-Pitch Dry Screw Vacuum Pumps | VOCs recovery and clean gas evacuation matched with condensing units | 100% oil-free pumping chamber prevents solvent pollution, with variable pitch profile lowering exhaust temperature for safe vapor handling |
| Closed-Loop Liquid Ring Vacuum Systems | Environmental plant gas extraction and continuous industrial emission control | Packaged with gas-liquid separators, heat exchangers, and service liquid recirculation to eliminate secondary wastewater discharge |
| DVBL Roots + Liquid Ring Vacuum Systems | Heavy moisture loads requiring higher displacement or deeper vacuum than single pumps | Staged Roots booster integration delivers expanded pumping speed and deeper working vacuum under humid and condensable conditions |
Environmental projects vary in vapor load, wet gas content, site layout, and auxiliary process requirements. DV Vacuum provides engineering support and system matching based on actual project conditions.
The solvent-vapor load may exceed the condenser or backing-pump capacity. Check condenser temperature, separator drainage and inlet-filter pressure drop. If these are normal, verify whether the system was sized for peak solvent evaporation rather than chamber volume alone.
Yes. The DVB Roots–dry screw system provides additional pumping capacity during vapor surges. Pressure interlocks and variable-frequency control adjust the pump load, reducing vacuum fluctuations and overload risk.
Yes. DVB Roots pumps cover nominal pumping speeds from 250 to 40,000 m³/h and can be combined with different backing pumps. The system is selected according to peak solvent load, target pressure and required drying time.
The actual vapor load may exceed the condenser or backing-pump capacity. Check condenser temperature, separator drainage, inlet-filter pressure drop and system leakage. The vacuum unit must be sized according to peak solvent evaporation—not chamber volume alone.
