    There is no science involved..only politics.
    It's been proven sunlight destroys covid.. so why keep indoors where the air is dirtier and recycled constantly.... most air filters are NOT changed on time and actually hurt the system by making it work longer and harder.
    Again NO ONE I know has gotten sick and it's been proven in my state the numbers were greatly fudged upwards.

    Who wants (or needs) to be going back over and over to repair the same issue - particularly when the unit we're talking about just isn't very expensive.
    As for interchangeability......There is no compatibility across generations of machines to the best of my knowledge.
    I remember once trying a C2800 K pump in a C3500 (or vice versa) and it didn't work.
    However, if I remember correctly, you can swap the Y/K pumps, and also the C/M pumps within the same model range. I believe the only difference being length of the hose that comes with them.
    We were ordering black pumps to use in ALL colours when we were repairing these models.
    Vac out the existing hose and fit the new K pump in whatever colour was required.

    And if the Teflon coating on the inside of the hose to prevent clogging is damaged???

    in a pinch if needed.

    out of personal curiosity I tried to understand the fault, using a bench power supply, on one that I replaced a month ago.
    the problem seems to be the clutch, which has lost its strength, I replaced it with an MP2000 from the paper transport, but I haven't had the chance to test it yet, also because we only have a couple of units around that use that pump, I didn't notice any flaws in the rubber part, at least visually
