Frequently Asked Questions
What is the vacuum extraction rate range covered by the LGB series?
The LGB series covers a wide vacuum extraction rate range from 10 L/S (LGB-10) up to 400 L/S (LGB-400), making it suitable for both small-scale laboratory applications and large-scale industrial processes.
What is the limiting pressure for all LGB series models?
All models in the LGB series share a consistent limiting pressure of 5 Pa, ensuring reliable and stable vacuum performance across the entire product range.
Do smaller LGB models require cooling water?
No. The smaller models — LGB-10, LGB-15, and LGB-20 — do not require cooling water (0 L/min). Cooling water is only required starting from the LGB-50 model and above, with flow requirements increasing as power and capacity increase.
What operating speed do all LGB series pumps run at?
All LGB series models operate at a consistent speed of 2900 rpm, ensuring uniform and predictable performance characteristics regardless of the selected model size.
How much cooling water does the largest model (LGB-400) require?
The LGB-400, which has a power rating of 37 KW and a vacuum extraction rate of 400 L/S, requires a cooling water supply of 30 L/min to maintain safe and efficient operating temperatures.
How do I select the right LGB model for my application?
Model selection should be based on the required vacuum extraction rate (L/S) for your process, available power supply (KW), and whether a cooling water supply is accessible. For applications requiring higher throughput, models such as LGB-200, LGB-300, or LGB-400 are recommended. Please consult with our technical team for a customized recommendation.
