• Very low noise level in any working condition
• Customized configurations possible
• Simplified maintenance and service

The TRIVAC B range is available in six different sizes with an ultimate pressure of 10-4 mbar and a pumping speed in the range of 4 m3/h to 65 m3/h.

Industrial vacuum pumps for the rough vacuum industry.

The CLAWVAC series of oil-free industrial dry vacuum pumps have a corrosion-resistant pump chamber and stainless-steel claws. This makes them extremely robust, especially for challenging applications which include handling of particles and vapor-contaminated gases. The CLAWVAC dry vacuum pumps are simple to use, easy to clean onsite and have efficient air cooling that let’s our customers experience a trouble-free and cost-saving operation.

CLAWVAC can replace your liquid ring vacuum pump.

Thanks to its unique design, CLAWVAC combined with the right Leybold accessories can replace a liquid ring vacuum pump in many processes.

Switch to dry claw technology for cost savings:

• Huge cost savings: no water consumption, no water treatment or disposal
• Lower power consumption
• Stable process performance, independent of water temperature
• Better environmental impact of your industrial plant, as water is a valuable asset

• The dry vacuum pumps of the SCROLLVAC plus family operate on the principle of a scroll compressor
• A scroll pump consists of two engaged spiral forms. One scroll form is mounted eccentrically to the other and is made to move in an orbiting path relative to the fixed scroll. This creates crescent shaped volumes that are driven from the outside to the inside of the forms thereby pumping the gas
• Increased pumping speed combined with low ultimate pressures, low power consumption and low noise levels
• Gas ballast allows for pumping of condensable vapors including water, solvents, dilute acids, and bases
• Latest in tip seal technology: allows for significantly longer intervals between tip seal changes
• Integrated smart drive with auto sensing voltage input, delivers optimized pumping performance globally
• Designed to be field serviceable

The RUVAC WH / WHU series pumps are high throughput, hermetically sealed, water-cooled roots blower pumps with high efficiency motors that provide optimum price-to-performance ratio. Both motors and oil reservoirs are water cooled thereby perfectly balancing the internal temperature management of the pumps.

RUVAC WHU pumps are equipped with a bypass line and may be operated at its maximum power from atmospheric pressure. The WHU is equipped with improved valve technology for maximum efficiency in short cycle operation. The integrated bypass line allows for the WHU pumps to be operated starting at atmospheric pressure while the unique control flap provides extreme contamination resistance.
