The TRIVAC B line covers sizes D 4 B, D 8 B, D 16 B, D 25 B, D 40 B, and D 65 B with pumping speeds from 4 to 65 m³/h. Units integrate a built-in fluid pump, a hydraulically controlled anti-suckback valve, and gas ballast for exhausting mixtures containing high water vapor volumes.

Six displacement capacity classes tailored for analytical and shop-floor setups
Hydraulic anti-suckback valve preventing fluid migration into the vacuum volume
Integrated gas ballast valve delivering exceptional tolerance to water vapor
Exchangeable inner body assembly enabling prompt overhaul and component swap

Energy-efficient TRIVAC L series dual-stage vacuum pumps

The TRIVAC L generation introduces modernized rotary vane pumps with optimized fluid paths and advanced air cooling. A patented fluid reservoir layout decreases operating oil temperatures, extending the service life of internal bearings, dynamic seals, and exhaust valves.

Efficient air-cooling system reducing thermal degradation of working lubricants
Three-stage gas ballast regulation for handling humid industrial gas streams
Bare shaft options available without electric motor for custom drive integration
Multi-position intake and exhaust flanges supporting vertical or horizontal piping

TRIVAC BCS specialty chemically resistant vacuum pumps

TRIVAC BCS variants are engineered for chemical synthesis, semiconductor processing, and vacuum metallurgy. These pumps are filled with non-flammable perfluoropolyether (PFPE) fluids and incorporate reinforced fluorocarbon FKM elastomer seals for handling aggressive process atmospheres.

Full compatibility with synthetic PFPE inert fluids resistant to oxidation
Fluoroelastomer FKM O-rings providing defense against corrosive process media
Integrated monitoring sensors for real-time oil pressure and fluid level metrics
ATEX-compliant configurations suitable for environments with explosive gas hazards

TRIVAC maintenance kits and consumable overhaul components

To sustain ultimate vacuum parameters and routine servicing, comprehensive Minor Kit sealing packs and Major Kit overhaul packages are available. Product selections include composite vanes, radial shaft seals, valve springs, exhaust valve plates, and calibrated chamber gaskets.

Minor Kit preventative maintenance sets containing complete elastomer O-rings
Major Kit overhaul packages including rotary vanes, springs, and coupling inserts
Precision composite vanes engineered with high resistance against abrasive wear
High-temperature fluoroelastomer radial shaft lip seals preventing fluid leaks

Leybold LVO vacuum pump oils and TRIVAC oil mist filters

Reliable rotary pump performance depends on Leybold vacuum oils such as LVO 100 and LVO 130 formulas alongside effective exhaust treatment. AF exhaust mist separators and chemical sorption traps capture oil aerosols, returning condensed fluids into the reservoir.

Mineral and synthetic LVO lubricant formulas featuring low saturated vapor tension
Exhaust mist elimination filters delivering aerosol retention efficiency over 99%
Intake particle filters and cold condensable traps guarding internal pump chambers
Condensate drain ports and automatic oil return lines lowering fluid consumption

German vacuum engineering heritage and TRIVAC brand evolution

The TRIVAC dual-stage oil-sealed rotary vane vacuum pump family was developed by German vacuum pioneer Leybold GmbH in Cologne.

Across decades of continuous industrial operation, TRIVAC pumps have served as an international benchmark for operational stability and long service life throughout analytical laboratories, chemical research facilities, and demanding manufacturing plants.

Their oil-sealed design maintains deep vacuum levels near 10⁻⁴ mbar while keeping noise and vibration to an absolute minimum.

Every TRIVAC pump assembly undergoes high-precision rotor-stator balancing and factory leak testing.

The utilization of wear-resistant surface treatments and robust metal alloys guarantees that factory pumping speeds and ultimate pressure metrics remain stable even throughout round-the-clock production regimes in harsh manufacturing environments.

Design features and forced lubrication hydraulics of TRIVAC B series

The flagship TRIVAC B series encompasses six standard displacement sizes from 4 to 65 m³/h across models D 4 B, D 8 B, D 16 B, D 25 B, D 40 B, and D 65 B. An integrated gear pump delivers positive fluid lubrication directly into sleeve bearings regardless of intake pressure.

This mechanism maintains continuous hydrodynamic lubrication and uniform thermal dissipation under heavy pumping cycles.

A hydraulically actuated internal anti-suckback valve closes the intake tract immediately when power is interrupted. This design prevents atmospheric air ingress and oil migration into the client vacuum chamber without requiring external electromagnetic isolation valves on the intake flange.

Thermal management and energy-saving technology in TRIVAC L pumps

The modern generation TRIVAC L series was engineered to decrease total cost of ownership while maximizing thermal stability. Optimized fluid reservoir geometries and enhanced air-cooling airflow decrease lubricant operating temperatures.

Reduced fluid heating prevents lubricant breakdown and sludge formation, extending the operational life of bearings, vanes, and valves.

TRIVAC L units feature versatile flange orientations allowing either vertical or horizontal piping integration into equipment layouts. Bare shaft options supplied without motors provide flexibility for integration alongside custom explosion-proof motors or specialized regional drive systems.

Specialized TRIVAC BCS chemical configurations for corrosive media

For industrial processes releasing corrosive, reactive, or oxidizing gases, Leybold developed the specialized TRIVAC BCS configuration.

These models utilize non-flammable perfluoropolyether (PFPE) synthetic fluids exhibiting total chemical inertness when exposed to pure oxygen, halogen compounds, and acidic vapors.

All internal static and dynamic seals in BCS variants consist of chemical-grade FKM fluoroelastomers to prevent seal swelling and degradation during chemical exposure. Integrated pressure sensors and temperature transmitters enable automated condition monitoring within plant automation networks.

Scheduled maintenance and application of Minor and Major overhaul kits

To simplify preventative maintenance, standard Minor Kit sealing packages and Major Kit overhaul packages are available. The Minor Kit contains all replacement O-rings, flat gaskets, and radial shaft lip seals required during every scheduled inspection and cleaning of the internal pump module.

The comprehensive Major Kit includes precision-machined rotor vanes, tension springs, exhaust valve assemblies, and alignment pins. Utilizing factory-assembled maintenance packages eliminates component selection errors, reduces downtime, and restores original ultimate vacuum performance.

Exhaust aerosol filtration and Leybold LVO vacuum fluid selection

Long-term reliability of rotary vane pumps depends upon routine lubricant renewal using qualified fluids. For standard industrial tasks, mineral-based Leybold LVO 100 provides low vapor pressure and stable viscosity.

For high-temperature or cyclical duties, synthetic LVO 130 formulas provide enhanced oxidation resistance.

To prevent aerosol emissions into ambient factory air, AF exhaust oil mist separators featuring borosilicate microfiber filter elements are installed on the exhaust port.

These separators trap over 99% of aerosol particles and return condensed fluid back into the pump reservoir via automated return lines.
