Frequently Asked Questions
Q
What is the vacuum extraction rate range available across the LGB series models?
The LGB series covers a wide range of vacuum extraction rates, starting from 10 L/S on the LGB-10 model and going up to 400 L/S on the LGB-400 model, making it suitable for both small-scale and large-scale industrial vacuum applications.
Q
Do all LGB series models operate at the same speed?
Yes, all models in the LGB series operate at a consistent speed of 2900 rpm, ensuring stable and reliable performance across the entire product lineup.
Q
Which LGB models require cooling water, and how much is needed?
The smaller models — LGB-10, LGB-15, and LGB-20 — do not require cooling water (0 L/min). Starting from the LGB-50 model, cooling water is required. The flow rate increases with model size, ranging from 8 L/min for LGB-50 up to 30 L/min for LGB-400.
Q
What is the limiting pressure for the LGB series vacuum pumps?
All models in the LGB series share a uniform limiting pressure of 5 Pa, indicating a high level of vacuum performance that is consistent regardless of the pump size or power rating.
Q
How do I select the right LGB model for my application?
Model selection should be based primarily on the required vacuum extraction rate (L/S) and available power supply (KW). For higher-capacity needs, also consider your facility's cooling water supply, as models from LGB-50 onwards require a continuous cooling water flow. Consulting the specification table above will help match your process requirements to the appropriate model.
Q
What power supply is required for the LGB-400, the largest model in the series?
The LGB-400 requires a power supply of 37 KW, making it the most power-intensive model in the series. It delivers the highest vacuum extraction rate of 400 L/S and requires 30 L/min of cooling water for proper thermal management during operation.
