The MULTSEA Micro Oil Screw Vacuum Pump (VLM series) is designed for applications where moderate oil use (micro-lubrication), energy savings, and precision control are key—filling the gap between oil-free and fully oil-flooded pumps.

|---|---|
Automotive Component Manufacturing: In brake disc machining or engine part casting, micro-oil lubrication reduces rotor wear (extending pump life) while avoiding excessive oil residue that could contaminate machined surfaces. The VLM’s stable vacuum (0.06 Kpa.A for VLM4.5-96) ensures consistent clamping of parts during CNC milling.
Chemical & Petrochemical Processing: For solvent recovery (e.g., ethanol or acetone) in chemical reactors, the VLM’s VSD+ system adjusts vacuum levels to match solvent volatility—preventing over-suction and reducing solvent loss. Its built-in air filter traps dust and chemical residues, protecting internal components.
Laboratory & Research Facilities: In material science labs (e.g., vacuum drying of polymers) or analytical equipment (e.g., mass spectrometers), the VLM’s quiet operation (≤70 dB) and precise pressure control (±0.1 Kpa) avoid disrupting experiments. Its compact size (1100×850×1320 mm for VLM4.5-96) fits under lab benches.
Printing & Packaging: For flexographic printing (where vacuum holds rolls of film in place), the VLM’s peak traffic (up to 5100 m³/h for VLM90-96) handles high-speed printing lines, while micro-oil lubrication reduces maintenance downtime compared to dry pumps.
VSD+ Energy Savings: Within a 20-100% flow range, the VLM’s variable speed drive (VSD+) delivers up to 50% average energy savings compared to fixed-speed vacuum pumps. It eliminates peak current surges during startup, protecting your electrical system and reducing fuse/cable sizing costs by 30%.
Micro-Oil Lubrication: A precise oil injection system uses minimal oil (≤5 ml/h) to lubricate rotors—reducing wear without oil carryover. This balances durability (5-7 year lifespan) and cleanliness, making it ideal for industries where oil-free pumps are too costly.
Integrated Smart Control: The color screen controller monitors motor speed, temperature, and pressure in real time, allowing one-touch adjustments. It also complies with the 2004/108/EG electromagnetic compatibility (EMC) standard, avoiding interference with nearby electronics (e.g., lab equipment).
Flexible Sizing & Cooling: With 11 models (VLM4.5-96 to VLM90-96), the VLM covers peak traffic from 380 m³/h to 5100 m³/h. Air or water cooling options adapt to environments from cool labs (15°C) to warm factories (45°C).
Q1: How is "micro-oil" different from fully oil-flooded pumps?
A1: Micro-oil pumps use 90% less oil than oil-flooded models, and a high-efficiency separator traps oil vapor—so no oil reaches your process. This avoids product contamination while still providing rotor lubrication (unlike dry pumps, which wear faster).
Q2: Does the VLM require special oil?
A2: Yes, use MULTSEA’s recommended food-grade or industrial-grade vacuum pump oil (depending on your industry). This oil is formulated to resist oxidation and maintain viscosity at high temperatures, ensuring optimal performance.
Q3: Can the VSD+ system be adjusted remotely?
A3: Yes, the VLM’s controller supports Modbus communication, allowing remote monitoring and adjustment via your factory’s SCADA system. This is ideal for facilities with multiple pumps or off-site management.
Q4: What maintenance is required for the VLM?
A4: Replace the air filter every 8 months, change the oil every 12 months, and clean the oil separator annually. Routine checks take <30 minutes, and the controller alerts you to maintenance needs—minimizing downtime.
