The molecular pump has a default port size. For example, the flange size of FB-2000 (2000L/s) is 250. If the customer’s equipment only has a 200-diameter, what should we do?
The interface of the EVP brand FB series molecular pump can be changed to a smaller size according to the customer’s needs. The flange can be changed to a smaller size. For example, the FB-2000 interface 250 can be changed to 200. There are two ways:
A: Directly change the pump body interface size to 200
B: The pump body remains unchanged, add a reducing diameter, the reduced diameter changes from 250 to 200
Will changing the diameter result in a decrease in the pumping speed?
Yes, the pumping speed will drop by about 10% after reducing the flange size. Continuing to take FB-2000 as an example, the pumping speed of FB-2000 is about 2000L/s. If it is changed to size 200, the pumping speed of FB-2000 with 20 caliber pump is about 1800 L/s.
