The MULTSEA VDM Oil-Free Screw Vacuum Pump is engineered to address critical pain points across industries where cleanliness, energy efficiency, and stable performance are non-negotiable.

|---|---|
Food & Beverage Processing: In vacuum packaging for meat, dairy, or baked goods, oil contamination risks product safety and FDA compliance. The VDM’s oil-free design eliminates oil carryover, ensuring packaged foods meet hygiene standards while maintaining a tight vacuum seal to extend shelf life.
Electronics & Semiconductor Manufacturing: Semiconductor wafers and electronic components are sensitive to oil residues, which can cause short circuits or defects. The VDM delivers a stable vacuum (down to 20 Kpa.A) and low noise, creating a clean, interference-free environment for wafer bonding and chip assembly.
Pharmaceutical Production: GMP-certified facilities require contamination-free vacuum for lyophilization (freeze-drying) of drugs and vaccines. The VDM’s air/water cooling options adapt to strict temperature controls, while its intelligent frequency conversion system avoids pressure fluctuations that could compromise product potency.
Packaging & Printing: For vacuum thermoforming of plastic trays or vacuum adsorption in label printing, the VDM’s high peak traffic (up to 23,000 m³/h for VDM315) ensures fast, consistent suction—reducing production bottlenecks compared to slower water ring pumps.
Oil-Free & Low-Maintenance Design: No oil lubrication means zero oil changes, lower maintenance costs, and no risk of oil pollution. An external air filter and built-in first-level muffler further reduce upkeep and noise (≤75 dB).
Exceptional Energy Efficiency: Compared to traditional water ring vacuum pumps (which consume 37 KW for 1100 m³/h at 80 Kpa), the VDM uses just 18.5 KW for the same suction capacity—cutting energy costs by ~49%. Its permanent magnet variable frequency (PMV) control adjusts speed to real-time demand, saving an additional 20-30% on electricity.
Flexible Cooling & Sizing: Choose air cooling for compact spaces (e.g., small workshops) or water cooling for high-temperature environments (e.g., foundries). With 14 models (from VDM7.5 to VDM315), the VDM fits capacities from 450 m³/h to 23,000 m³/h, matching any production scale.
Stable & Intelligent Operation: The fully automatic frequency conversion system maintains consistent pressure, avoiding the pressure drops common in fixed-speed pumps. Installation sizes (e.g., 1150×850×1320 mm for VDM7.5) are compact, saving floor space in crowded facilities.
Q1: Why is oil-free operation critical for my industry?
A1: Oil-free vacuum prevents product contamination (critical for food/pharma) and avoids damage to sensitive equipment (e.g., semiconductor chips). It also eliminates oil disposal costs and compliance risks with environmental regulations.
Q2: How do I choose between air cooling and water cooling?
A2: Air cooling is ideal for ambient temperatures ≤35°C and areas without water access (e.g., mobile labs). Water cooling is better for high-heat settings (≥40°C) or continuous 24/7 operation (e.g., large-scale manufacturing) to prevent overheating.
Q3: What is the lifespan of the VDM Oil-Free Screw Vacuum Pump?
A3: With proper maintenance (filter replacements every 6-12 months), the VDM’s durable screw rotor design ensures a lifespan of 8-10 years—2-3 years longer than water ring pumps.
Q4: Can the VDM replace my existing water ring pump?
A4: Yes. The VDM’s suction capacity and pressure range (20 Kpa.A to atmospheric) match or exceed water ring pumps, and its smaller footprint and lower energy use make retrofitting easy. Most customers see a return on investment (ROI) within 12-18 months.
