For around 90 years, vacuum manufacturer Leybold has been offering the TRIVAC, a universally applicable rotary vane pump. The robust, oil-sealed vacuum pump combines many advantages and is used in industrial and research applications – for generating pressures in the rough and fine vacuum range and as a backing pump that can be combined with Roots, diffusion, turbomolecular, and cryogenic pumps. Leybold has now developed the TRIVAC L, a new model of the proven two-stage rotary vane vacuum pump with optimized air cooling.

Leybold offers the TRIVAC in pumping speed classes ranging from 5.8 to 92/110 m³/h (50/60 Hz)
Suitable for vertical and horizontal alignment
This innovation offers users the ideal balance of performance, reliability, and efficiency. This makes the TRIVAC L ideal for meeting the requirements of modern, sustainable vacuum processes. In production environments with high humidity, the patented three-stage gas ballast ensures optimized water vapor tolerance. It is also equipped with standard flanges for inlet and outlet connections. The outlet is suitable for vertical and horizontal alignment. This makes the rotary vane pump ideal for use in analytics, research and development, metallurgy, the production of air conditioning systems and heat pumps, the freeze-drying of food and pharmaceuticals, and the coating of carrier materials for semiconductor or solar technology.
Available in different pumping speed classes
Leybold offers the TRIVAC in pumping speed classes ranging from 5.8 to 92/110 m³/h (50/60 Hz). The vacuum specialist also provides customized designs and specifications for models with special requirements regarding motors, oils, or systems. For the standard TRIVAC L, variants are available for all motor options across different regions worldwide. “The patented design of the oil housing is an ergonomic advantage,” explains Product Manager Jane Li. “It reduces the oil temperature and extends the service life of the oil,” she adds. For easy and efficient operation, the pump is equipped with a sight glass for monitoring the oil level and a standard drain valve for applications requiring frequent oil changes.
Cost-effective solution and simplified maintenance
The TRIVAC L is easy to use: Mechanical improvements have increased the robustness of the components, significantly extending the operating time in the processes. Low power consumption, energy-efficient motors, and user-friendly on-site service round off the package of benefits for users and result in low total operating costs compared to conventional rotary vane pumps.
Range of innovative service solutions
To prevent prolonged production downtime, Leybold offers its customers a comprehensive range of innovative service solutions: These include oil and spare parts, in-house service and on-site service, pump module exchange service, certified used vacuum pumps, and pump rental. “The TRIVAC L vacuum pumps also come with an extensive range of accessories, enabling them to be optimally adapted to the individual requirements of different applications,” adds Product Manager Jane Li.
