(1) LG model is same pitch screw pump, LGB is variable pitch screw pump. (2) The speed of reaching high vacuum with LGB model is slower than that with LG. (3) The LGB model cannot operate between 1ATM to 10000 Pa for a long time because the load is too large. When the vacuum degree is better than 10000 Pa, it is recommended to use LGB.
