Product Description

GWSPS Oil free Scroll Vacuum Pump

Working principle:
GWSPS 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.

Basic informations:
1) Model: GWSPS300 Oil free scroll vacuum pump
2) Ultimate vacuum pressure: 8.0Pa/0.08 mbar (abs.)
3) Max suction capacity: 50Hz-4.4l/s 60Hz-5.3l/s

Safety Precautions:
The GWSPS series oil free scroll vacuum pumps are suitable for clean processes only. 
Do not pump toxic, explosive, flammable or corrosive substances or substances which contain chemicals, solvents or particles.GEOWELL will not perform maintenance work on pumps which have used special gases or other hazardous substances. 
Be sure the inlet gas temperature must be lower than 122 °F.

What factors should one consider when choosing a small vacuum pump for a specific task?

Choosing the right small vacuum pump for a specific task is essential to ensure optimal performance and efficiency. Several factors should be taken into account when making your selection:

1. Vacuum Level Requirements:

Determine the required vacuum level for your application. Some tasks may require a high vacuum level, while others can be accomplished with a lower vacuum. The pump’s ultimate vacuum capability should match your needs.

2. Flow Rate:

Consider the volume of gas or air that needs to be evacuated or processed per unit of time. Choose a pump with an adequate flow rate to meet your application’s requirements. Insufficient flow can lead to slow or inefficient processes.

3. Type of Gas:

Identify the type of gas or vapor you will be handling. Some gases may be corrosive, reactive, or incompatible with certain pump materials. Ensure that the pump you select is compatible with the gases involved in your task.

4. Contamination Sensitivity:

If your application demands a clean and contamination-free vacuum environment, consider pumps that operate without oil lubrication, such as diaphragm or scroll pumps. These pumps are suitable for applications like analytical instruments and cleanroom environments.

5. Power Source:

Determine the available power source for your pump. Small vacuum pumps can be electric, battery-powered, pneumatic, or even hand-operated. Choose a power source that aligns with your application’s requirements and availability.

6. Portability:

If mobility is essential, opt for a compact and lightweight vacuum pump. Battery-powered or pneumatic pumps are often chosen for portable applications. Consider the size and weight of the pump relative to the device or equipment it will be integrated into.

7. Noise Level:

Assess the noise level generated by the pump. Some small vacuum pumps operate quietly, which is advantageous in noise-sensitive environments like laboratories and medical facilities. Low-noise pumps are also suitable for handheld devices.

8. Maintenance Requirements:

Consider the maintenance needs of the pump. Some pumps have simpler designs and require less frequent servicing. Evaluate factors such as filter replacement, lubrication, and ease of access for maintenance tasks.

9. Cost and Budget:

Take into account your budget constraints. Small vacuum pumps come in a range of price points, so choose one that offers the best balance between performance and cost while meeting your specific requirements.

10. Environmental Considerations:

Consider environmental factors, especially if your application is in a sensitive or regulated area. Assess energy efficiency, emissions, and any environmental certifications or standards that the pump may need to meet.

11. Application Specifics:

Finally, closely examine the unique requirements of your specific task. Each application may have its own considerations, so tailor your choice to suit the precise demands of your project or process.

By carefully evaluating these factors, you can select the most appropriate small vacuum pump for your specific task, ensuring that it performs efficiently and effectively.
