Frequently Asked Questions
Q
What is the vacuum extraction rate range available in the LGB series?
A
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 various industrial vacuum applications.
Q
What is the limiting pressure for all LGB series models?
A
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
Which LGB models require cooling water and how much?
A
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) up to 30 L/min (LGB-400), increasing proportionally with pump capacity.
Q
What is the operating speed (rpm) of LGB series pumps?
A
All LGB series models operate at a uniform speed of 2900 rpm, providing consistent rotational performance and simplifying motor selection and integration for end users.
Q
What power range does the LGB series cover?
A
The LGB series spans a power range from 1.1 KW (LGB-10) to 37 KW (LGB-400), allowing users to select the most energy-efficient model that meets their specific vacuum capacity requirements.
Q
How do I choose the right LGB model for my application?
A
Selecting the right model depends primarily on your required vacuum extraction rate (L/S) and available power supply. For smaller systems with limited infrastructure, models like LGB-10 to LGB-20 are ideal as they require no cooling water. For higher-capacity industrial processes, models from LGB-50 to LGB-400 offer greater throughput with proportional power and cooling water requirements.
