This is our lab first time using a G1312B SL Bin Pump. The pressure we are getting is quite unusual.
We have replaced the seals, the frit, outlet ball valve and tested other pieces. Now, after replacing the damper, the pressure is stable yet still inconsistent with what we are used to.
For instance, open valve, 5ml IPA, 100% A1, we are getting >40 bar. With close valve, 2ml IPA A1, we are getting 33-34bar stable.
Any thoughts would be appreciated.
