Frequently Asked Questions
Q
What is the vacuum extraction rate range available in the LGB series?
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 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 lineup.
Q
Do the smaller LGB models require cooling water?
No. The LGB-10, LGB-15, and LGB-20 models do not require cooling water (0 L/min). Cooling water is only needed for larger models starting from LGB-50 and above, with requirements increasing as power and extraction rate go up.
Q
What is the operating speed (rpm) of LGB series pumps?
All LGB series models operate at a uniform speed of 2900 rpm, which ensures consistent rotational performance and simplifies maintenance and spare parts management across the entire range.
Q
How much cooling water does the LGB-400 require?
The LGB-400, being the largest model in the series with a power rating of 37 KW and an extraction rate of 400 L/S, requires 30 L/min of cooling water to maintain optimal operating temperatures during continuous use.
Q
How do I select the right LGB model for my application?
Selecting the right model depends on your required vacuum extraction rate, available power supply, and whether a cooling water supply is accessible. For light-duty or space-limited installations, LGB-10 to LGB-20 are ideal. For high-throughput industrial processes requiring extraction rates above 100 L/S, consider LGB-120 through LGB-400.
