How often does EVP-200PB series scroll pump replace the sealing strip?

EVP-200PB 3L/s scroll pump is recommended to replace the sealing strip after about 8000 hours of operation, because after about 8000 hours, the pump cannot reach 10Pa within 20 minutes.

If the customer does not have strict requirements on the working vacuum, for example, the customer requires the vacuum to be 130-260Pa, then it is estimated that the customer can replace the sealing strip after about 20,000 hours.

If the customer wants a longer time without changing the sealing strip, please indicate in the order, we can clamp the sealing strip of the pump tighter, so that the sealing strip is less likely to be worn, but the time required to reach the same vacuum degree is correspondingly It has to be increased, and the time has to be increased by about 40 to 50%. Because the sealing strip is tighter, the gas volume of the pump can only be about 2L/s at the beginning, and the gas volume can return to 3L/s as the vacuum degree rises.
