With the series VX100Q, VX136Q and VX186Q, the starting torque can be reduced by installation of thin
wear plates (series …QVVA excepted) or by the installation of shims between rotary lobes and wear plates.
Increasing the gaps between rotary lobes and wear plates however reduces the volumetric efficiency.
