Frequently Asked Questions
Q
What is the vacuum extraction rate range available in 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 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 a reliable and stable vacuum level across the entire product range.
Q
Which LGB models require cooling water, and how much is needed?
Models LGB-10, LGB-15, and LGB-20 do not require cooling water (0 L/min). Starting from LGB-50, cooling water is required, ranging from 8 L/min (LGB-50) to 30 L/min (LGB-400). Higher-capacity models require greater cooling water flow to maintain optimal operating temperatures.
Q
What is the operating speed (rpm) across all LGB series models?
All LGB series models operate at a uniform speed of 2900 rpm. This consistent operating speed ensures stable performance and simplifies maintenance and replacement procedures across the entire product line.
Q
How do I select the right LGB model for my application?
Selecting the right model depends primarily on your required vacuum extraction rate (L/S) and available power supply (KW). Match your system's required pumping speed to the corresponding model. Also consider whether your installation can supply adequate cooling water for larger models (LGB-50 and above).
Q
What power supply is required for the LGB-400, and what extraction rate does it deliver?
The LGB-400 is the highest-capacity model in the series, requiring 37 KW of power. It delivers a vacuum extraction rate of 400 L/S with a limiting pressure of 5 Pa, making it ideal for large-scale industrial vacuum systems demanding high throughput performance.
