    our velo 3 dosing pump has started having a shorter stroke, we have adjusted all the way. no joy
    any ideas

    Genuinely shorter stroke, or simply not pumping in as much? If not pumping in as much, perhaps the non return valves are not sealing properly, so allowing some backflow in the pump system.
