  • Page 41: Suction Capacity/Bleeding

    Commissioning Liquid end without bleed valve • Connect discharge line to liquid end, however not to injection version TT, SS valve. • Operate metering pump with stroke length/stroking rate 100% and pressure-free discharge line by simultaneously pressing the -keys until the medium has completely filled the liquid end without any bubbles.

  • Page 42: Metering Accuracy

    Commissioning • Start the pump with stroke length/stroking rate at 100% and discharge line free of pressure by simultaneously pressing the keys until the medium has completely filled the liquid end and is free of bubbles. This can be verified by the medium being visible in the discharge or bleed line.
  • Page 43 Commissioning Accurate metering is only possible if the counter pressure remains fairly constant; this should be above 1 bar. When metering with atmospheric discharge, an injection valve with 0.5 bar response pressure should be assembled at the end of the line. Or a back-pressure valve should be assembled directly onto the liquid end in order to create and maintain a counter pressure of approx.
