Volm Screw Vacuum Systems Successfully Replace Top-Tier International Brands

Volm Screw Vacuum Systems Successfully Replace Top-Tier International Brands

In 2019, a leading chemical enterprise in China faced critical equipment failures in its core production line. Since its commissioning in 2017, their internationally branded screw vacuum systems had suffered progressive performance degradation, directly impacting production stability. Mr. Li, Head of Equipment Department, stated: "The system’s designed capacity was 200 tons/hour, but actual output dropped to 150 tons/hour with escalating maintenance costs." After installing Volm’s screw vacuum systems in August 2019, operational data showed dramatic improvements. Over subsequent years, the company ordered 50 vacuum systems from Volm, fully replacing the original international brand.

Race Against Time: Volm Vacuum Pumps Secure Production in 32°C Heatwave

Race Against Time: Volm Vacuum Pumps Secure Production in 32°C Heatwave

In the summer of 2022, a fine chemical plant in East China faced critical production bottlenecks in solvent recovery. Their existing liquid ring-Roots system suffered vacuum degradation from the designed -0.098 MPa (G) to -0.07~-0.08 MPa (G) at ambient temperatures ≥32°C. This caused downstream Roots pumps to fail, forcing production cuts. Plant Manager Wang noted: "Last July-August, weekly output averaged just 6 tons with moisture content spiking to 12%, driving customer complaints up 400% YoY." To address energy efficiency and yield demands, Volm replaced the system with a screw-Roots system (DMY600 Roots + DMY300 Roots + ESDP900 Screw Pump), enabling year-round stable operation.

Volm Conical Liquid Ring Compressors: Safeguarding Green Chemical Production—AMPS/AMPS-Na Case Study

Volm Conical Liquid Ring Compressors: Safeguarding Green Chemical Production—AMPS/AMPS-Na Case Study

Under global green chemistry trends, AMPS and AMPS-Na have replaced traditional toxic additives. In one production project, compressing 1,000 Nm³/h acrylonitrile-containing gas to 0.55 MPa(G) demanded extreme safety—acrylonitrile ignites upon heat exposure, releasing toxic fumes. Volm's HPM Conical Liquid Ring Compressor, using acrylonitrile as working fluid, delivered a breakthrough solution.

Volm Two-Stage Liquid Ring Vacuum Pumps Empower Efficient and Stable PVC Production

Volm Two-Stage Liquid Ring Vacuum Pumps Empower Efficient and Stable PVC Production

In PVC suspension polymerization processes, vacuum pumps are critical across six core stages: reactor deoxygenation, post-polymerization degassing, wet material drying, and monomer recovery. Particularly in vacuum drying, maintaining 60~80°C is essential to protect PVC’s heat-sensitive particles from thermal degradation. The client requires 5~15 kPa(A) vacuum (far below single-stage liquid ring pump’s efficient range of 20 kPa(A) to atmospheric pressure). Leveraging deep industry expertise, Volm Pump delivered a customized two-stage liquid ring vacuum pump solution, ensuring stable performance across all PVC production stages.

Volm Liquid Ring Compressors Enable Efficient Desulfurization & Green Emission Reduction in Sichuan High-Sulfur Gas Field

Volm Liquid Ring Compressors Enable Efficient Desulfurization & Green Emission Reduction in Sichuan High-Sulfur Gas Field

A high-sulfur gas field in Sichuan faced plummeting desulfurization efficiency (40%) in its gas stripping system due to water quality changes, resulting in effluent sulfur levels of 1,500 mg/L. This triggered excessive chemical consumption, sludge buildup, and environmental violations. Volm Pump’s customized vacuum stripping solution delivered 90% desulfurization efficiency and 150 mg/L effluent sulfur, cutting chemical costs by 74% while eliminating H₂S leakage risks.
