Simple and compact structure
Composed of counter-rotating screws, pump body, end cover, sealing components, etc., the structure is very simple
Independently produced and manufactured
Independently produced and manufactured, with over 40 patent technologies, rated as a high-tech enterprise and a science and technology enterprise, and has passed ISO9001 quality management system certification
Dry operation
Dry operation, no need for any working medium, thus no oil pollution, no wastewater discharge, and significant energy-saving effect
Reliable processing accuracy
Core components are processed by imported processing equipment from Japan, with precision up to 0.001mm
No friction in the pumping chamber
There is a certain gap between the screw and the pump body
Provide three corrosion-resistant material options
Nickel-phosphorus alloy, Hastelloy alloy, Teflon
High vacuum degree
A single screw dry vacuum pump can replace a three-stage Roots pump water ring vacuum unit
Can be combined with Roots pumps to form a vacuum system
Can be combined with Roots pumps to form a vacuum system, achieving higher ultimate vacuum degree and increasing pumping speed
Low noise
generally around 80 decibels

Frequently Asked Questions
Q: What is the range of vacuum extraction rates for the LGB series?
The LGB series offers a wide range of vacuum extraction rates, starting from 10 L/S with the entry-level LGB-10 model up to 400 L/S with the heavy-duty LGB-400 model.
Q: What is the standard limiting pressure for these vacuum pump models?
All models in the LGB series, from LGB-10 to LGB-400, maintain a consistent and reliable limiting pressure of 5 Pa.
Q: Do all LGB models require cooling water during operation?
No, smaller models including LGB-10, LGB-15, and LGB-20 do not require cooling water (0 L/min). Cooling water requirements for larger models range from 8 L/min (LGB-50) up to 30 L/min (LGB-400).
Q: What is the operational speed of the LGB series vacuum pumps?
All models in this series operate at a uniform rated speed of 2900 rpm, ensuring stable and consistent performance across different configurations.
Q: How does power consumption scale across the LGB product line?
Power requirements scale with capacity, beginning at a minimum of 1.1 KW for the LGB-10 model and reaching up to 37 KW for the high-capacity LGB-400 model.
