Frequently asked questions

Common questions about KAISHAN from 3G Electric.

What are the available models in the Kaishan KRSV series of high vacuum rotary vane pumps?

The Kaishan KRSV series includes models such as KRSV-010AV4S8U (7 kW, 286 cfm), KRSV-025AV4S8U (18 kW, 800 cfm), KRSV-030AV4S8U (22 kW, 982 cfm), KRSV-050AV4S8U (37 kW, 1,343 cfm), KRSV-075AV4S8U (55 kW, 2,248 cfm), and KRSV-125AV4S8U (90 kW, 2,505 cfm). All models operate on 460V AC three-phase power and feature flange connections. These pumps are designed for continuous-duty industrial vacuum applications. The range allows selection based on required free air displacement and motor power. Each model is identified by a specific manufacturer part number for ordering.

What is the maximum vacuum level achievable with Kaishan KRSV rotary vane pumps?

Kaishan KRSV series rotary vane pumps are high vacuum pumps, but the exact ultimate vacuum level depends on the specific model and operating conditions. Typically, oil-sealed rotary vane pumps can achieve ultimate pressures in the range of 0.1 to 1 mbar (absolute). For precise specifications, refer to the manufacturer's technical documentation for each model. The pumps are suitable for applications requiring rough to medium vacuum, such as packaging, material handling, and general industrial processes. They are not intended for high vacuum applications below 0.1 mbar without additional stages. Always consult the performance curve for the specific model to determine vacuum level at given flow rates.

What maintenance is required for Kaishan KRSV high vacuum rotary vane pumps?

Maintenance for Kaishan KRSV rotary vane pumps includes regular oil changes, oil filter replacement, and inspection of vanes and seals. The oil should be checked periodically for contamination and replaced according to the manufacturer's recommended interval, typically every 500 to 2,000 hours depending on operating conditions. The oil filter should be replaced at each oil change. Vanes may wear over time and require replacement; inspect them during scheduled maintenance. The inlet filter should be cleaned or replaced to prevent debris from entering the pump. Always follow the maintenance schedule in the operation manual to ensure reliable performance and longevity. Proper maintenance helps maintain vacuum efficiency and prevents premature failure.

Can Kaishan KRSV pumps be used in packaging applications?

Yes, Kaishan KRSV high vacuum rotary vane pumps are suitable for packaging applications, including vacuum packaging, thermoforming, and pick-and-place systems. Their continuous-duty design and range of displacements allow them to handle the vacuum requirements of various packaging machines. For example, the KRSV-025AV4S8U with 800 cfm is often used in medium-sized packaging lines, while larger models like the KRSV-075AV4S8U with 2,248 cfm can support high-speed or large-format packaging equipment. The flange connection facilitates integration with existing vacuum systems. Ensure the pump is sized appropriately for the required vacuum flow and that the packaging materials are compatible with oil-sealed vacuum pumps. Consult the application guidelines for specific recommendations.

What voltage and phase do Kaishan KRSV rotary vane pumps require?

All Kaishan KRSV series high vacuum rotary vane pumps listed by 3G Electric operate on 460V AC, three-phase power. This is a common industrial voltage in North America and other regions with similar electrical standards. The pumps are not available in single-phase or other voltage configurations within this series. Ensure your facility has the appropriate power supply and that proper motor protection and wiring are in place. For installations in regions with different voltages, a step-up or step-down transformer may be required, but this should be evaluated by a qualified electrical engineer. Always verify the nameplate voltage before installation.

How does 3G Electric support the Kaishan KRSV product line?
