Vane Pump

The DVP SC Series is a range of oil-free rotary vane pumps engineered in Italy for industrial applications that demand clean, oil-free operation. Using self-lubricating graphite vanes and a dry-running design, the SC Series delivers reliable vacuum and compression performance across capacities up to 150 m³/h — without a single drop of oil entering the process stream. Winston Engineering now carries the full DVP SC range in Singapore, making it the go-to vane pump solution for food, medical, packaging, and OEM applications.

DVP SC Series — Oil-Free Rotary Vane Pump

The DVP SC Series is a family of oil-free vane pumps manufactured in Italy by DVP Vacuum Technology. The pump mechanism consists of a cylindrical body and an eccentrically-mounted rotor with grooves housing graphite vanes. As the rotor turns, centrifugal force pushes the vanes outward against the housing wall, creating variable-volume chambers that draw gas in at the inlet and expel it through the outlet — all without any oil in the pumping chamber.

The SC Series spans from compact OEM-sized units (SC 5) through to large industrial models (SC 140), and uniquely, all models can function as both a vacuum pump and a low-pressure compressor — giving OEM equipment designers maximum flexibility in a single platform.

Key Technical Highlights

• Dual function: Operates as vacuum pump and low-pressure compressor
• Discharge: Completely oil-free — no mist separator required
• Motor options: AC single-phase, AC three-phase, 24V DC (CC models)
• Design: Monobloc industrial design — rotor directly on motor shaft
• Cooling: Fan-cooled motor for continuous operation
• Origin: Italy 🇮🇹

Features of the DVP SC Series Vane Pump

1. Completely Oil-Free Operation

The SC Series uses graphite vanes that are inherently self-lubricating. No oil is introduced into the pumping chamber at any point, making the discharge stream completely clean. This eliminates the need for oil mist separators and makes the pump fully compliant with food-grade and medical application requirements.

2. Dual Vacuum and Compression Capability

All SC Series vane pumps can operate as a vacuum pump and as a low-pressure compressor (up to 0.6 bar on SB 10 and SB 12 models). This dual functionality reduces the number of components required in OEM machine designs where both functions are needed.

3. Long-Life Graphite Vanes

The highly durable graphite vanes combined with low internal operating temperatures result in extended vane life and reduced maintenance intervals. On SC 60 and SC 80 models, a removable front grid allows direct vane access without disassembling the full conveyor casing — a significant time-saving advantage on production lines.

4. Compact Monobloc Design

The rotor is mounted directly onto the motor shaft, eliminating coupling components and reducing the overall footprint. This makes the SC Series well-suited to OEM integration into space-constrained machines and enclosures.

5. Energy-Efficient Across the Full Pressure Range

On SC 60 and SC 80 models, optimised suction and discharge phase geometry means energy consumption remains consistent from atmospheric pressure to maximum vacuum — improving efficiency on variable-load applications.

6. 24V DC Variants for Portable and OEM Equipment

SC CC models (e.g., SC 5CC, SC 8CC) are available with 24V DC motors, making them ideal for battery-powered portable equipment, medical devices, and vehicle-mounted systems where AC power is unavailable.

Applications

The DVP SC Series oil-free vane pump is trusted across a wide range of industries where clean, dry vacuum or low-pressure air is required:

• Food & Beverage — Oil-free discharge meets food safety requirements for vacuum packaging, filling, and product handling.
• Medical & Dental — Silent, oil-free operation is essential for chairside dental suction, inhalation therapy, and pressotherapy machines.
• Packaging — Continuous vacuum generation for MAP packaging, tray sealing, bag filling, and blister packaging lines.
• Printing & Paper — Sheet feeding, vacuum impression cylinders, and silk-screen printing require consistent, clean vacuum.
• Wood Presses — Vacuum clamping and membrane pressing for CNC woodworking and veneering equipment.
• Vacuum Lifting — Ergonomic suction cup lifting of sheet materials, glass panels, and flat packaging.
• Analytical & Sampling — Pollutant sampling, gas analysis instrumentation, and laboratory filtration requiring oil-free airflow.
• Construction Industry — Vacuum anchorage, formwork, and surface preparation equipment.
• Pneumatic Conveying — Aspiration-based conveying of granules, powders, and lightweight materials (SC 60 / SC 80).

Frequently Asked Questions — Vane Pump

What is a vane pump?

A vane pump is a positive-displacement pump that uses sliding vanes mounted in a rotor to move fluid or gas. As the rotor turns eccentrically inside a cylindrical housing, centrifugal force pushes the vanes outward, creating sealed chambers that expand to draw in gas and compress to expel it. Vane pumps are used in both vacuum and hydraulic applications across many industries.

What is the difference between an oil-free vane pump and an oil-lubricated vane pump?

An oil-free vane pump like the DVP SC Series uses graphite vanes that are self-lubricating — no oil enters the pumping chamber, making the discharge completely clean. This suits food, medical, and clean-room environments. An oil-lubricated vane pump like the DVP LC Series uses oil to seal and cool the vanes, achieving deeper ultimate vacuum levels (down to 0.1 mbar) but requires an oil mist separator at the exhaust.

Can a vane pump work as both a vacuum pump and a compressor?

Yes. The DVP SC Series vane pump is dual-function — it can operate as a vacuum pump and as a low-pressure compressor, making it a versatile solution for OEM equipment manufacturers who need both functions in a single compact unit.

What industries use oil-free vane pumps?

Oil-free vane pumps are widely used in food and beverage, pharmaceutical, medical devices, dental equipment, packaging, printing and paper, silk-screen printing, wood presses, vacuum lifting, analytical instrumentation, pressotherapy machines, and pollutant sampling and analysis.

How long do the graphite vanes in a DVP SC Series vane pump last?

The DVP SC Series uses highly durable graphite vanes that benefit from low internal operating temperatures for extended service life. On SC 60 and SC 80 models, a removable front grid provides direct vane access without disassembling the full conveyor casing, minimising replacement downtime.
