Global Leading Market Research Publisher QYResearch announces the release of its latest report “Mag Drive Liquid Ring Vacuum Pump – Global Market Share and Ranking, Overall Sales and Demand Forecast 2026-2032″. Based on current situation and impact historical analysis (2021-2025) and forecast calculations (2026-2032), this report provides a comprehensive analysis of the global Mag Drive Liquid Ring Vacuum Pump market, including market size, share, demand, industry development status, and forecasts for the next few years.
The global market for Mag Drive Liquid Ring Vacuum Pump was estimated to be worth US$ 113 million in 2025 and is projected to reach US$ 155 million, growing at a CAGR of 4.7% from 2026 to 2032. In 2024, global production of magnetically driven liquid ring vacuum pumps reached 3,778 units, with an average selling price of US$29,500 per unit. A magnetically driven liquid ring vacuum pump is a leak-free, sealed fluid machine that combines magnetic transmission technology with the principles of a liquid ring vacuum pump. Its core structure consists of a magnetic coupling, pump body, impeller, and liquid ring forming system. Power transmission is achieved through contactless magnetic coupling between an external permanent magnet or electromagnet and an internal driven magnet, replacing traditional mechanical seals or packing seals. During operation, an appropriate amount of working fluid (such as water or oil) is injected into the pump chamber. As the impeller rotates, centrifugal force causes the fluid to form concentric rings, dividing the pump chamber into multiple crescent-shaped working chambers. Gas is drawn in, compressed, and discharged through volume changes, creating a vacuum environment.
The magnetic drive liquid ring vacuum pump industry chain covers three major links: upstream raw materials and core components supply, midstream manufacturing technology integration and downstream terminal applications: the upstream is centered on special metal materials (such as stainless steel 316L, alloy steel), fluoroplastics (PTFE/PFA), ceramics, etc., and key components are provided by Baosteel, Tata Steel, Kobe Steel (special steel), Germany’s MANN+HUMMEL (seals), Japan’s NSK (bearings) and other companies. Domestic Lanzhou Highland Pump Industry has broken through the bottleneck of corrosion-resistant materials through independent research and development of fluoroplastic magnetic pumps. International suppliers such as Sweden’s Atlas Copco Group have integrated magnetic pumps and liquid ring system technologies through the acquisition of Shandong Bozhong Vacuum; the midstream is divided into high-end customization and standardized production. International leaders Atlas Copco and Gardner Denver dominate the semiconductor and new energy fields, while domestic companies such as Shanghai Shangcheng Pumps and Valves and Bozhong (Shandong) Industrial Equipment focus on fluoroplastic magnetic pumps and MVR evaporation systems in the pharmaceutical and chemical industries. Emerging companies include Qingyu Pumps, Suli Pumps and Valves, and Huaxing Group. Their downstream products are widely used in high-corrosion and high-vacuum scenarios, including chemical pharmaceuticals, new energy, environmentally friendly foods, semiconductors, and other fields, forming an industry trend of deep integration of material upgrades, process integration, and terminal demand.

Market Landscape & Recent Data (Last 6 Months, Q4 2025–Q1 2026)
The global mag drive liquid ring vacuum pump market is concentrated among global vacuum pump leaders and specialized magnetic drive pump manufacturers. Key players include STERLING SIHI, Flowserve, Sundyne, Iwaki, Klaus Union, HERMETIC, Verder, March Manufacturing, KSB, NASH, Atlas Copco, Gardner Denver, Busch Vacuum Solutions, Graham Corporation, Tuthill Vacuum and Blower Systems, Ingersoll Rand, SPX Flow, Edwards, Pfeiffer Vacuum, EBARA, and Tsurumi Manufacturing.
Three recent developments are reshaping demand patterns:
- Semiconductor manufacturing expansion: Semiconductor fabs (chip etching, deposition, packaging) require oil-free, leak-free vacuum pumps (mag drive eliminates seal leaks, contamination risk). Semiconductor segment grew 15-18% in 2025 (global fab construction, equipment upgrades).
- Chemical and pharmaceutical process safety: Handling corrosive, toxic, flammable gases requires zero-leakage pumps. Mag drive liquid ring pumps (no mechanical seals) preferred over traditional sealed pumps. Chemical and pharmaceutical segment grew 8-10% in 2025.
- Material upgrades (316L, PTFE, PFA) : Corrosion-resistant materials extend pump life in aggressive environments (HCl, H₂SO₄, HF, solvents). Fluoroplastic (PTFE/PFA) lined pumps for chemical service. Material upgrade segment grew 5-7% in 2025.
Technical Deep-Dive: Single-Stage vs. Dual-Stage
- Single-Stage mag drive liquid ring vacuum pump (one impeller, one liquid ring). Advantages: lower cost ($20,000-35,000), higher pumping speed (100-1,000 m³/h), suitable for rough vacuum (50-100 mbar absolute). A 2025 study from the Vacuum Technology Association found that single-stage pumps meet 80-85% of chemical, pharmaceutical, and food processing applications. Disadvantages: limited ultimate vacuum (50-100 mbar). Single-stage accounts for approximately 60-65% of mag drive liquid ring pump market volume (largest segment), dominating chemical, pharmaceutical, food processing, and general industrial vacuum applications.
- Dual-Stage (two impellers in series, two liquid rings). Advantages: lower ultimate vacuum (10-33 mbar absolute), higher compression ratio, and suitable for applications requiring deeper vacuum (semiconductor, solvent recovery, vacuum drying). Disadvantages: higher cost ($35,000-60,000), larger footprint, more complex. Dual-stage accounts for approximately 35-40% of volume, dominating semiconductor, high-vacuum chemical processing, and pharmaceutical drying applications.
User case example: In November 2025, a semiconductor fab (300mm wafer, 50,000 wafers/month) published results from deploying dual-stage mag drive liquid ring vacuum pumps (Atlas Copco, Edwards, Ebara) for dry etch and CVD chambers (process vacuum, leak-free). The 12-month study (completed Q1 2026) showed:
- Pump type: dual-stage mag drive (magnetic coupling, no dynamic seals).
- Ultimate vacuum: 15 mbar (process requirement).
- Leak rate: zero (no mechanical seal wear).
- Materials: 316L stainless steel (corrosion resistance to process gases).
- MTBF (mean time between failures): 30,000 hours (vs. 15,000 for mechanical seal pumps).
- Cost per pump: $45,000 (dual-stage) vs. $25,000 (single-stage). Payback period (reduced downtime + no seal replacement): 18 months.
- Decision: Dual-stage mag drive for process vacuum (critical tools); single-stage for rough vacuum (ancillary).
Industry Segmentation: Discrete vs. Continuous Manufacturing
- Mag drive liquid ring vacuum pump manufacturing (magnetic coupling assembly, impeller casting/machining, pump body fabrication (316L, PTFE/PFA lined), assembly, testing) follows batch discrete manufacturing (low volume, high value). Production volumes: thousands of units annually.
- Magnetic coupling components (magnets (samarium-cobalt, neodymium), can (hastelloy, titanium)) are high-value discrete components.
Exclusive observation: Based on analysis of early 2026 product launches, a new “mag drive liquid ring vacuum pump with integrated VFD and IoT monitoring” is emerging for predictive maintenance and energy optimization. Traditional pumps operate at fixed speed. VFD (variable frequency drive) allows speed adjustment (vacuum level control, energy savings (30-50%)). IoT sensors monitor vibration, temperature, and magnetic coupling health. Atlas Copco, Gardner Denver, and Busch launched smart mag drive pumps in Q1 2026, targeting semiconductor and chemical plants. Smart pumps command 20-30% price premium ($50,000-80,000 vs. $35,000-60,000).
Application Segmentation: Chemical Industry, Pharmaceutical Industry, Food Processing, Semiconductor Manufacturing, Other
- Chemical Industry (chemical processing, solvent recovery, distillation, evaporation, drying) accounts for 30-35% of mag drive liquid ring vacuum pump market value. Single-stage dominates; dual-stage for high-vacuum processes. Corrosion-resistant materials (316L, PTFE, PFA) required.
- Pharmaceutical Industry (API manufacturing, vacuum drying, solvent recovery, distillation) accounts for 20-25% of value. Single-stage and dual-stage. GMP-compliant materials (316L, electropolished).
- Semiconductor Manufacturing (dry etch, CVD, PVD, deposition, wafer handling) accounts for 15-20% of value. Dual-stage dominates (low ultimate vacuum). Fastest-growing segment (12-15% CAGR).
- Food Processing (vacuum packaging, freeze drying, concentration) accounts for 10-15% of value. Single-stage dominates. Food-grade materials (316L).
