2SK Series Two-Stage Water Ring Vacuum Pump - High Vacuum High Pumping Speed CE Certified

Product Description

The 2SK series two-stage water ring vacuum pump is a high-performance vacuum equipment developed in China in the 1980s, which is equivalent to two SK series single-stage water ring vacuum pumps used in series. It is specially designed to solve the problem that the SK series can only reach a limit vacuum of -700mmHg, and achieves higher vacuum degree and larger pumping speed in the high vacuum area, meeting the needs of high vacuum application scenarios.

Compared with single-stage vacuum pumps, this series adopts a unique double-impeller structure, which fundamentally improves the vacuum performance. Its ultimate vacuum degree can reach -735mmHg (-0.098MPa), and the 2SK-P1 series two-stage water ring vacuum pump-atmospheric jet pump unit can even reach -750mmHg, showing excellent high vacuum performance. At the same pumping rate, its shaft power is higher than that of 2BV and 2BE1 series products, ensuring stable operation under high load conditions.

The product is widely used in various industrial fields that require high vacuum, such as chemical engineering, pharmaceutical, food processing, vacuum drying, material processing, etc. It uses clean water as the working medium, which is environmentally friendly and easy to obtain. The overall structure is compact, and the installation is convenient with standardized foundation dimensions. It should be noted that due to the double-impeller structure, the manufacturing and maintenance are relatively complex, and there are more vulnerable parts. For long-term operation in the high vacuum area, it is recommended to match the Roots+water ring vacuum unit to obtain the best pumping efficiency.

With reliable performance and mature technology, the 2SK series two-stage water ring vacuum pump has become an important choice for industrial production that requires high vacuum. We provide complete after-sales service and technical support to ensure the stable operation of the equipment for customers. At the same time, we also provide recommended alternative products according to different working conditions to meet the diverse needs of customers for energy saving and efficiency improvement.

Notices

1. Before installation, check whether the product model, accessories and technical documents are complete, and confirm that the packaging is intact without damage.

2. The installation shall be carried out in accordance with the outline and installation dimensions provided in the manual, and the foundation shall be firm and flat to ensure the stable operation of the pump.

3. The working medium shall be clean water without particles to avoid abrasion of the impeller and other components. The water supply shall meet the specified requirements, and the water temperature shall be controlled at about 15℃ as much as possible.

4. During the operation, regularly check the operating status of the pump, including vacuum degree, pumping speed, noise, temperature rise, etc. If abnormal phenomena are found, stop the machine for inspection in time.

5. The vulnerable parts shall be inspected and replaced regularly according to the maintenance cycle. When replacing the parts, use the original accessories provided by the manufacturer to ensure the performance of the equipment.

6. For long-term operation in the high vacuum area (absolute pressure 10-50mmHg), it is recommended to configure the Roots+water ring vacuum unit to improve the operating efficiency.

7. When disassembling and maintaining the pump, cut off the power supply first to ensure the safety of the operator.

8. The performance parameters of the product are measured under specified conditions. If the working conditions change, the performance may be affected. It is necessary to adjust and use it according to the actual situation.

Applications

Widely used in chemical engineering (vacuum distillation, vacuum drying), pharmaceutical industry (drug crystallization, vacuum concentration), food processing (vacuum packaging, freeze-drying), material processing (vacuum impregnation, vacuum coating), electronic industry (semiconductor manufacturing, vacuum sputtering), and other fields that require high vacuum degree and stable pumping speed. It is also suitable for occasions where single-stage vacuum pumps cannot meet the vacuum requirements, and can provide reliable vacuum support for industrial production processes.

FAQ
