7.5KW Oil-free single-stage screw vacuum pump

A single-stage oil-free Screw Vacuum Pump is a vacuum equipment that adopts the principle of screw air compression. Its core components are two counter rotating screws that achieve gas compression through meshing motion, without the need for lubricating oil throughout the process, ensuring a highly clean output gas. This pump has the advantages of being clean and pollution-free (avoiding oil vapor reflux), energy-saving and efficient (with a volumetric efficiency of over 85%, which is 20-30% more energy-efficient than traditional pumps), stable and reliable (non-contact operation, with an average time between failures of over 20000 hours), and easy to maintain (only requiring regular replacement of the intake filter) and complying with environmental regulations. Its working pressure range is wide (10Pa to 1000hPa), and it can be directly started from atmospheric pressure. Typical applications include vacuum mounting and plastic packaging in the semiconductor industry, packaging of electronic components for new energy vehicles, vacuum sealing in food processing, and other fields that require strict cleanliness and stability.

 

The single-stage oil-free screw Vacuum Pump adopts the screw compression principle to achieve clean and oil-free operation (completely avoiding lubricating oil pollution, with an output gas purity of over 99.9%), and has high efficiency and energy-saving characteristics (with a volumetric efficiency of over 85% and energy consumption reduced by 20-30% compared to traditional oil lubrication pumps). At the same time, it achieves an ultra long service life (with an average trouble free operation time of over 20000 hours) through non-contact screw design, and has extremely low maintenance costs (only requiring regular replacement of the intake filter). Its wide pressure range (10Pa to 1000hPa) supports direct start-up from atmospheric pressure and meets strict environmental regulations, making it particularly suitable for industrial scenarios such as semiconductors and food packaging that require extremely high purity and reliability.

 

Single stage oil-free screw vacuum pumps are widely used in fields with strict requirements for gas purity and process reliability due to their clean, oil-free, efficient, and stable characteristics. They are used in semiconductor manufacturing for vacuum environment construction in wafer mounting and plastic packaging processes; Vacuum degassing for battery pack packaging and motor insulation treatment in the field of new energy vehicles; Realize high-speed aseptic sealing in the food packaging process; Simultaneously covering scenarios such as medical equipment (such as vacuum drying sterilization), photovoltaic industry (lamination process), and scientific research instruments (electron microscope vacuum system), effectively avoiding oil pollution risks and meeting continuous operation requirements.
