Product Description:

  • Dry & Oil-Free Design, Clean Gas Source

    Fully dry operation without lubricant or circulating water inside the pump chamber. The extracted gas will not be polluted by oil or water, fully meeting clean process demands of pharmaceutical, food, semiconductor and precision electronic industries. No oil pollution discharge for better environmental protection.

  • Non-Contact Rotor, Long Service Life & Low Maintenance

    High-precision screw rotors operate without metal contact to minimize wear. Only a small number of wearing parts such as seals and bearings are required. Long maintenance cycle greatly reduces spare parts cost and labor cost, ideal for long-term continuous production.

  • Wide Working Condition Adaptability & Medium Compatibility

    It works well with fine dust, condensed vapor and weak corrosive medium, breaking the limitations of traditional vacuum pumps. Suitable for complex processes such as chemical solvent recovery, material drying and waste gas extraction. One pump fits multiple production scenarios.

  • Multiple Material Options, Anti-Corrosion & Durable

    Standard cast iron for general conditions; PTFE anti-corrosion coating for humid and slightly corrosive environments; 316 stainless steel for medium corrosive gas. The integrally cast body is sturdy with excellent pressure and deformation resistance.

  • Stable Vacuum Performance & Uniform Pumping

    Optimized rotor profile and flow channel design deliver high ultimate vacuum and stable pumping speed with small pressure fluctuation. It keeps production process parameters stable and avoids defective products caused by abnormal vacuum.

  • Low Noise & Vibration, Workshop-Friendly

    Excellent dynamic balance design ensures operating noise below 72dB and low vibration. No additional noise reduction equipment is needed, complying with noise standards of overseas factories.

  • Multiple Safety Protection & Reliable Operation

    Multi-stage mechanical seals prevent air leakage. Independent anti-backflow valves protect the pump from medium backflow after shutdown. Forced air cooling avoids high-temperature failure. IP54 dust-proof and splash-proof design ensures safe operation under multiple protections.

  • Flexible Supply & Complete Supporting Parts

    We support single unit export, bulk supply of standard spare parts and custom complete vacuum units. Complete vacuum systems combined with filters, vacuum tanks, valves and electric control cabinets are available to meet one-stop procurement demands of overseas customers.
