Key advantages of the GVS rotary oil vacuum pumps include:

• easy installation thanks to a compact design
• high reliability due to a robust design and optimal oil retention at all pressure levels
• low maintenance and wear and tear due to optimally selected shaft speeds
• low noise and vibration levels over the entire pressure range

Applications and use examples of the GVS series vacuum pumps in real life:

• The vacuum pumps are used as vacuum pre-pumps for Roots vacuum pumps and diffusion vacuum pumps.
• GVS technology can be used in the food industry as a source for vacuum packaging of food.
• They are used in the woodworking industry for material handling and pneumatic transport.
• In plastics and rubber production, they are used for hot shaping processes, degassing of the extruder barrel, or degassing of molds.
• In the printing industry, they are implemented to printing machines, where they supply pneumatic energy.
• Vacuum pumps are also used in the healthcare sector. Here they play a role of a medical vacuum during suction processes.

Two-stage rotary oil vacuum pumps GVD

The GVD series two-stage rotary oil vacuum pumps have a low final pressure, and their operation is quiet. The vacuum pump itself is compact and vibration-free. It is equipped with a fan and connecting fittings.

The key parameters of the GVD series two-stage oil vacuum pumps include:

• effective lubrication even under high loads
• no reverse suction when the vacuum pump is switched off
• gas ballast management helps when pumping high loads
• reliability and long service life
• clear oil level indicator
• easy maintenance and installation
• wide range of accessories

Applications and use examples of the GVD series of two-stage oil vacuum pumps:

• The more powerful GVD 275 series is designed for vacuum metallurgical processes. It is used in evacuation of cooling and air conditioning systems, drying and distillation in vacuum, for freezing and for cryogenics. The GVD 275 vacuum pumps are also used for drying and impregnating oil treatment equipment.
• Lower series, such as GVD 3, GVD 5, GVD 8, GVD 12 and GVD 28, are suitable for laboratory vacuum and analytical instruments. However, they are also used as support vacuum pumps for turbomolecular systems.

Oil-lubricated screw vacuum pumps GHS VSD+

The GHS VSD+ and GHS 350-1900 VSD+ series are two new series of the rotary screw vacuum pumps with VSD technology. The vacuum pumps have been designed to deliver an optimal performance at any operating pressure. The GHS 350-900 VSD+ series is an ideal solution for production areas where a central vacuum pump is required. The GHS 1300-1900 VSD+ vacuum pump can be used as a dedicated vacuum pump for a specific machine, but is more commonly used in central vacuum systems.

Key parameters of screw vacuum pumps of the GHS VSD+ series include:

• increased efficiency thanks to the state-of-the-art technology
• variable speed drive (VSD) and innovative motor design
• very quiet operation
• plug-and-play installation
• ideal for installation in compressor stations

The GHS VSD+ vacuum pumps are ideal for central systems and larger installations. For example:

• holding, lifting and other pneumatic applications
• molding and shaping of plastics, packages but also vehicle windscreens
• canning, vacuum packing of meat and poultry
• roofing and brick production
• heat processing and nitriding in metallurgy

DZS claw vacuum pumps and DZM vacuum solutions

DZS claw vacuum pumps are powerful vacuum pumps that provide vacuum in the range of 50-140 mbar (a), 28.3-25.8 Hg Vac. DZM units combine two to four DZS vacuum pumps (depending on the application) in a single compact housing. They are fitted with a cover that not only protects the vacuum pump, but also reduces the noise level. Their side walls are removable for quick access and easy maintenance.

The key advantages of the DZS claw vacuum pumps include:

• corrosion-resistant pumping chambers
• easy access for removing, cleaning and reassembling the claws
• The gearbox insulation eliminates the risk of oil contamination
• high efficiency IE3 motors
• motors compatible with the VSD+ technology
• modular design
• vacuum pumps offer a vacuum range of 50-140 mbar_(a)

Key advantages of the DZM vacuum solution include:

• ideal as a central vacuum source
• easy maintenance even in demanding conditions
• compact housing that protects and reduces noise levels
• precise vacuum adjustment pursuant customer requirements

AWS liquid-ring vacuum pumps and AWD two-stage vacuum pumps

The single-stage AWS units have a pumping speed of up to 5,500 m³/h and can achieve a vacuum in excess of 200 mbar_(abs), which is ideal for general processes such as filtration or draining and pumping or evacuation.

Two-stage direct-drive AWD vacuum pump models provide sustained high performance at operating pressures below 200 mbar_(abs). Two impellers work in series to achieve a high compression ratio and increased efficiency in continuous production processes such as drying, degassing, extraction and solvent restoration.

LRP intelligent liquid ring vacuum pumps with VSD technology
