Frequently Asked Questions
Q
What is the limiting pressure for all LGB series vacuum pump models?
A
All models in the LGB series — from LGB-10 to LGB-400 — share a consistent limiting pressure of 5 Pa, making them suitable for applications that require a stable and reliable high-vacuum environment.
Q
Which LGB models do not require cooling water?
A
The LGB-10, LGB-15, and LGB-20 models require 0 L/min of cooling water, meaning they are air-cooled and do not need a water cooling system. Models from LGB-50 onward require cooling water, with flow rates ranging from 8 to 30 L/min depending on the model.
Q
What is the operating speed (rpm) of the LGB series pumps?
A
All LGB series vacuum pumps operate at a uniform speed of 2900 rpm. This consistent rotational speed ensures stable performance and predictable vacuum extraction rates across the entire product range.
Q
How do I choose the right LGB model for my application?
A
Selection should be based primarily on the required vacuum extraction rate (L/S) and available power supply (KW). For smaller-scale or low-power applications, models like LGB-10 to LGB-20 are ideal. For industrial or high-volume processes, models such as LGB-300 or LGB-400 with extraction rates up to 400 L/S are recommended.
Q
What is the maximum vacuum extraction rate available in the LGB series?
A
The LGB-400 is the highest-capacity model in the series, offering a vacuum extraction rate of 400 L/S with a power consumption of 37 KW and a cooling water requirement of 30 L/min, making it suitable for large-scale industrial vacuum applications.
Q
How much cooling water does the LGB-400 model require, and why is it important?
A
The LGB-400 requires 30 L/min of cooling water. Adequate cooling water supply is critical for larger models to dissipate heat generated during high-power operation, ensuring long-term reliability, preventing overheating, and maintaining optimal pump performance and service life.
