DV Vacuum chemical vacuum solutions are designed for processes involving corrosive gases, solvent vapors, condensable media, and explosion-proof requirements.
Typical applications include vacuum distillation, solvent recovery, vacuum drying, crystallization, and degassing under demanding chemical process conditions.
Solution configurations are selected according to gas composition, vacuum level, corrosion conditions, and site safety requirements, using Roots vacuum pumps, dry screw vacuum pumps, liquid ring vacuum pumps, and engineered vacuum systems.
Chemical production often involves complex media and demanding process conditions. Many applications require low-pressure environments to reduce boiling points, remove residual solvents, improve separation efficiency, or protect temperature-sensitive materials during processing.
In addition, chemical plants frequently deal with flammable gases, corrosive substances, high vapor loads, and condensable media, which means vacuum equipment must be selected not only by pumping speed and vacuum level, but also by sealing method, corrosion resistance, material configuration, and explosion-proof requirements.
DV Vacuum supports chemical customers with both standard vacuum pumps and custom-engineered vacuum systems selected according to actual process requirements.
Used to separate compounds under reduced pressure, especially when materials are heat-sensitive or prone to decomposition at normal boiling temperatures.
Suitable for recovering methanol, ethanol, acetone, and other solvents via condensation, supported by high-efficiency equipment such as DVS-V Variable-Pitch Dry Screw Vacuum Pumps and integrated DVBS Roots + Dry Screw Systems.
Helps remove water or residual solvent under low-pressure conditions while protecting temperature-sensitive materials, frequently utilizing oil-free DVS Dry Screw Vacuum Pumps to prevent cross-contamination.
Supports cooling- or evaporation-driven crystal formation under vacuum conditions for more controlled separation and process stability.
Removes dissolved or trapped gases from liquids, intermediates, and process materials to support downstream process stability.
Applicable to selected processes involving flammable, reactive, or other special gas media where sealing performance, material selection, and safety design are critical.

Chemical process requirements vary depending on gas composition, solvent content, corrosion level, vacuum range, temperature, and site safety standards. DV Vacuum provides engineering support to help customers match the right pump type and system configuration to actual operating conditions.
Yes. Our pumps are designed for continuous duty. DVB roots + backing pump sets, dry screw and liquid ring types are all available for batch production with stable performance.
Wetted parts are protected with Hastelloy coating for acidic and solvent media, or Teflon coating for high-temperature wear-and-corrosion service. The bearing lubricant is isolated from the process gas by the shaft seal mechanical seal options depending on the media. For solvent-heavy streams, we recommend screw dry vacuum pumps, which allow direct vapor recovery instead of emission.
Every 12 months With good inlet filtration and proper condensate drainage: liquid ring pumps need inspection Every months, seal-fluid quality being the key factor; dry screw pumps typically run 8,000 hours between major services depending on gas load and dust content. Routine checks (oil level, cooling water, sound, vibration) take only minutes per shift. Detailed schedules are provided with each unit.
