Oil Sealed Rotary Vacuum Pumps: Reliable Performance for Industrial & Research Applications
At Ultrahivac, we specialize in delivering high-performance oil-sealed rotary vacuum pumps designed for precision, durability, and efficiency across diverse industries. From manufacturing and R&D laboratories to packaging and coating applications, these pumps are the backbone of vacuum-based processes that demand consistent results.
Oil-sealed rotary vacuum pumps are positive displacement pumps that use oil for sealing, lubrication, and cooling during operation. The oil creates an airtight seal between moving parts, ensuring smooth performance and achieving deeper vacuum levels compared to dry pumps.
They are known for:
- High reliability and long operational life
- Excellent performance in the low to medium vacuum range
- Cost-effective maintenance and easy operation
- Consistent results even under demanding industrial conditions
Ultrahivac Oil-Sealed Rotary Vacuum Pump Range
At Ultrahivac, we offer a complete range of oil-sealed rotary pumps engineered for various vacuum levels and application requirements.
Ideal for everyday vacuum operations, our single-stage rotary vane pumps are designed for simplicity and durability.
Key benefits:
- Compact and robust construction
- Efficient for medium vacuum applications
- Low noise and vibration
- Easy oil maintenance
Applications:
Packaging, plastics, food processing, medical suction systems, and general industrial vacuum tasks.
When deeper vacuum levels are required, the double-stage rotary vane pump delivers. It utilizes two compression stages to achieve higher vacuum efficiency and lower ultimate pressures.
Key benefits:
- Achieves higher vacuum (up to 0.005 mbar)
- Smooth and quiet operation
- Thermal protection and oil filtration for reliability
- Compact and energy-efficient design
Applications:
Research laboratories, coating and metallizing, solar and semiconductor industries, and vacuum drying systems.
The rotary screw vacuum pump is engineered for continuous, heavy-duty operations where high pumping speeds are required. Two intermeshing screw rotors compress the gas efficiently, with oil acting as both a sealant and coolant.
Key benefits:
- High pumping capacity and low vibration
- Suitable for 24/7 operation
- Minimal wear and low maintenance
- Long service life and energy efficiency
Applications:
Central vacuum systems, industrial automation, process industries, and large-scale manufacturing setups.
For specialized high-vacuum requirements, Ultrahivac offers robust rotary piston vacuum pumps. These pumps use a reciprocating piston mechanism, sealed and lubricated with oil, to achieve precise vacuum performance.
Key benefits:
- Reliable and durable for long-term operation
- Handles higher vacuum levels effectively
- Minimal leakage and high compression efficiency
Applications:
Vacuum furnaces, metallurgical processing, chemical and pharmaceutical industries, and research facilities.
- Expert Engineering: Decades of experience in designing and integrating vacuum systems.
- Comprehensive Range: From vane to piston and screw pumps, we cover every vacuum requirement.
- Quality Assurance: Every Ultrahivac pump is tested for performance, endurance, and leak integrity.
- Service & Support: Our technical team provides installation, oil maintenance, troubleshooting, and upgrades.
Maintenance Tips for Optimum Performance
To keep your oil-sealed rotary vacuum pump performing at its best:
- Regularly monitor and replace oil to maintain vacuum integrity.
- Check for leaks and ensure proper ventilation.
- Use recommended Ultrahivac oils and spares for longer service life.
- Schedule preventive maintenance to avoid downtime.
Conclusion
Oil-sealed rotary vacuum pumps remain the most dependable solution for low to medium vacuum requirements — balancing efficiency, cost, and performance. Whether you need a single-stage pump for packaging or a double-stage or screw pump for industrial research, Ultrahivac provides end-to-end vacuum solutions engineered for precision and reliability.
