Frequently Asked Questions
Q
What is the vacuum extraction rate range available for the LGB series pumps?
The LGB series offers a wide range of vacuum extraction rates, starting from 10 L/S (LGB-10) up to 400 L/S (LGB-400), making it suitable for both small-scale and large industrial vacuum applications.
Q
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.
Q
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 needed starting from the LGB-50 model and above, with requirements increasing as the pump size and power grow.
Q
What is the operating speed (rpm) for the LGB series pumps?
All LGB series models operate at a consistent speed of 2900 rpm, providing stable and efficient vacuum extraction performance regardless of the model size.
Q
How much power does the largest LGB-400 model consume?
The LGB-400 model, with a vacuum extraction rate of 400 L/S, requires 37 KW of power and 30 L/min of cooling water, making it ideal for heavy-duty industrial vacuum systems.
Q
Which LGB model is best suited for medium-scale vacuum applications?
For medium-scale applications, models such as the LGB-80 (80 L/S, 7.5 KW) or LGB-120 (120 L/S, 11 KW) are well-suited, offering a balanced combination of extraction capacity, power consumption, and manageable cooling water requirements.
