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, from 10 L/S (LGB-10) up to 400 L/S (LGB-400), making it suitable for both small-scale and large-scale industrial vacuum applications.
Q
What is the limiting pressure for all LGB series vacuum pumps?
All models in the LGB series share a consistent limiting pressure of 5 Pa, ensuring reliable and stable vacuum performance across the entire product line regardless of model size or power rating.
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 for the LGB-50 up to 30 L/min for the LGB-400. Higher-capacity models generally require more cooling water to maintain optimal operating temperatures.
Q
What is the operating speed (RPM) for LGB series vacuum pumps?
All LGB series models operate at a uniform speed of 2900 rpm. This consistent rotational speed across the entire range ensures standardized performance characteristics and simplifies maintenance and spare parts management.
Q
How do I select the right LGB model for my application?
Model selection should be based primarily on your required vacuum extraction rate (L/S) and available power supply (KW). For smaller applications with extraction needs up to 20 L/S, the LGB-10 to LGB-20 are ideal. For high-demand industrial processes requiring up to 400 L/S, the LGB-400 with 37 KW power is recommended. Also consider whether your facility can supply the necessary cooling water for models LGB-50 and above.
Q
What industries commonly use LGB series vacuum pumps?
LGB series vacuum pumps are widely used across multiple industries including semiconductor manufacturing, chemical processing, food packaging, pharmaceutical production, metallurgy, and scientific research laboratories. Their broad extraction rate range and consistent limiting pressure of 5 Pa make them versatile solutions for various vacuum-dependent processes.
