Replace with Brailsford Model TD3L2. Flow now set to 2.25 lpm during measurement cycle and 2.75 lpm during idle flush cycle. Run zero/span cycle and check flush time. OK still less that 30 sec to flush sample line 1 clean. Pressure controller now running at 936.38 mbar, set point at 3.51 volt, press sig at 3.51 v Perform diagnostics on KNF Neuberger pump in lab.
