Dry screw vacuum pumps have several notable features and advantages:
Oil-free and water-free operation: the pump operates without oil and water in the cavity to ensure a clean vacuum environment. This eliminates the generation of waste oil and waste water during the vacuum process.
Moisture and Dust Extraction: The pump is capable of extracting processes that contain moisture and dust. This feature is particularly useful in industries such as biotechnology and pharmaceuticals, electronics/photonics, and the food industry, where maintaining a clean and uncontaminated vacuum environment is critical.
Fast pumping speed and high vacuum degree: The pump has a fast pumping speed and can reach a high vacuum degree of 7.5x10-3 torr. This makes it suitable for applications requiring fast evacuation and high vacuum levels.
Chemical-grade design: The structural design of the pump is tailored to meet the requirements of chemical customers and demanding process levels. It uses a dual-channel shaft seal protection design (Lip seal) on both the high and low ends. This design increases the pump's resistance to process substances, preventing them from contaminating the tank and extending maintenance intervals.
Sturdy Construction: The rotor of the pump is integrally formed with alloy steel round rods, which ensures high strength and eliminates sand holes that may exist in ordinary castings. The casing and end plates are made of high-density alloy cast iron, which enhances wear resistance and corrosion resistance. The protective coating adopts DuPont Teflon paint, which has sufficient film thickness and strong covering power, and can effectively isolate corrosive substances.
Reliable and Service-Oriented: Vacuum pumps are entirely designed and manufactured by Risun, ensuring consistent quality and performance. Risun also provides an adequate supply of spare parts and fast service to ensure timely assistance when needed.
Custom Options: Pumps can be customized to meet specific process requirements. Risun can provide customized coating treatment solutions according to unique needs.
Additional options: For the MD Series, the pump is available with additional features such as water-cooled motors, human-machine interface, and cover plate metal versions at the same time.
Overall, dry screw vacuum pumps combine advanced design features, reliability, and customization options, making them suitable for a variety of industries that require clean, efficient vacuum operations.
