GWSP Oil free Scroll Vacuum Pump
Working principle:
GWSP oil free scroll vacuum pump is constructed with pump head assembly, crank pin assembly, bracket assembly, air flush assembly,and exhaust valve assembly.Two spiral cylinders, 1 offset and orbiting against the other fixed with an offset of 180° to form several crescent-shaped pockets of different sizes. By means of an eccentric drive, the orbiting scroll is made to orbit about the fixed scroll, reducing the volume of the pockets and compressing gas from outside towards the inside thereby pumping the gas from vacuum chamber.

Are scroll vacuum pumps environmentally friendly and compliant with regulations?
Scroll vacuum pumps are considered relatively environmentally friendly compared to some other types of vacuum pumps. Here's a detailed explanation:
Environmental Friendliness:
Scroll vacuum pumps offer several features that contribute to their environmental friendliness:
- Oil-Free Operation: Many scroll vacuum pumps are designed for oil-free operation. This eliminates the risk of oil contamination and the release of oil vapor or aerosols into the environment. Oil-free operation is particularly important in applications where a clean and particle-free vacuum environment is required, such as semiconductor manufacturing or research.
- Low Energy Consumption: Scroll pumps are known for their energy efficiency. They typically consume less energy compared to other vacuum pump technologies, resulting in reduced power consumption and lower environmental impact.
- Minimal Maintenance: Scroll vacuum pumps require minimal maintenance, which reduces the consumption of resources and minimizes waste generation associated with pump servicing or component replacement.
- Quiet Operation: Scroll pumps are designed to operate quietly, contributing to a more comfortable and environmentally friendly working environment by reducing noise pollution.
Regulatory Compliance:
Scroll vacuum pumps are designed and manufactured to comply with various regulations and standards, ensuring their safe and environmentally responsible operation. Some of the key regulations and standards that govern vacuum pumps include:
- European Union (EU) Regulations: Scroll vacuum pumps intended for sale or use within the European Union must comply with relevant directives, such as the Restriction of Hazardous Substances (RoHS) Directive and the Waste Electrical and Electronic Equipment (WEEE) Directive. These directives restrict the use of hazardous substances and promote the proper disposal and recycling of electronic equipment.
- International Electrotechnical Commission (IEC) Standards: IEC standards, such as IEC 61010 for electrical safety and IEC 61326 for electromagnetic compatibility, provide guidelines for the safe operation and performance of vacuum pumps and other laboratory equipment.
- Environmental Protection Agency (EPA) Regulations (United States): In the United States, scroll vacuum pumps must comply with environmental regulations enforced by the EPA, such as the Clean Air Act. These regulations aim to reduce emissions of ozone-depleting substances and other pollutants.
- Local and National Regulations: Depending on the jurisdiction, there may be additional local or national regulations governing the use, disposal, or emissions of vacuum pumps. Manufacturers ensure compliance with these regulations to meet the requirements of specific markets.
It is important to consult the manufacturer's specifications, certifications, and compliance statements to ensure that a particular scroll vacuum pump model meets the necessary environmental and regulatory standards for a given application or jurisdiction.
By choosing scroll vacuum pumps with oil-free operation, energy efficiency, minimal maintenance requirements, and compliance with regulations, users can contribute to a more environmentally friendly and sustainable vacuum system.
How do scroll vacuum pumps compare to other types of vacuum pumps in terms of performance?
Scroll vacuum pumps offer unique advantages and perform differently compared to other types of vacuum pumps. Here's a detailed comparison of scroll vacuum pumps with other common vacuum pump types:
1. Scroll Vacuum Pumps vs. Rotary Vane Pumps:
a. Oil Contamination: Scroll vacuum pumps operate without oil lubrication, eliminating the risk of oil contamination in the pumped gases or the surrounding environment. In contrast, rotary vane pumps require oil lubrication, which can introduce oil vapor or particles into the vacuum system.
b. Vibration and Noise: Scroll vacuum pumps operate with low vibration levels and produce less noise compared to rotary vane pumps. Rotary vane pumps can generate higher levels of vibration and noise due to the reciprocating motion of the vanes.
c. Ultimate Vacuum: Rotary vane pumps can achieve lower ultimate vacuum levels compared to scroll vacuum pumps. They are capable of reaching vacuum levels in the range of 10-3 to 10-4 millibar (mbar), while scroll vacuum pumps typically achieve vacuum levels in the range of 10-2 to 10-3 mbar.
2. Scroll Vacuum Pumps vs. Turbomolecular Pumps:
a. Pumping Speed: Turbomolecular pumps offer higher pumping speeds compared to scroll vacuum pumps. Turbomolecular pumps can achieve faster evacuation rates, making them suitable for applications that require rapid pumpdown or high gas flow rates.
b. Ultimate Vacuum: Turbomolecular pumps can achieve much lower ultimate vacuum levels compared to scroll vacuum pumps. They are capable of reaching vacuum levels in the range of 10-7 to 10-10 mbar, making them suitable for ultra-high vacuum (UHV) applications.
c. Complexity and Cost: Turbomolecular pumps are more complex and expensive compared to scroll vacuum pumps. They often require additional supporting equipment, such as backing pumps or foreline traps, which can increase the overall system complexity and cost.
3. Scroll Vacuum Pumps vs. Diaphragm Pumps:
a. Contamination Resistance: Scroll vacuum pumps offer better contamination resistance compared to diaphragm pumps. Diaphragm pumps can be prone to contamination when handling corrosive or particulate-laden gases.
b. Ultimate Vacuum: Scroll vacuum pumps can achieve lower ultimate vacuum levels compared to diaphragm pumps. Diaphragm pumps typically reach vacuum levels in the range of 10-2 to 10-3 mbar, similar to scroll pumps, but may have limitations in achieving deeper vacuum levels.
c. Durability: Scroll vacuum pumps are generally more durable and require less maintenance compared to diaphragm pumps. Diaphragm pumps utilize flexible membranes that can wear out over time and may require periodic replacement.
In summary, scroll vacuum pumps offer advantages such as oil-free operation, low vibration and noise levels, and contamination resistance. However, their ultimate vacuum levels may not match those of turbomolecular pumps or rotary vane pumps. The choice of vacuum pump depends on specific application requirements, including the desired vacuum level, pumping speed, contamination sensitivity, and budget constraints.
