    Hey guys

    I am bringing in a bunch of pumps. These are self priming and use a diaphragm. Great for ATU etc. WIll probably go for around R150 each. I am bringing in to see how they fare as dosing pumps connected to a controller (one of my projects)

    Is anyone interested? I will have about 15 available.

    - Empty load current: 0.18A
    - Load current: 0.3A
    - Max.flow: 2-3L/mins
    - Water output Max.pressure: 1-2.5kgs
    - Lift: 1-25m
    - Max. suction: 2m
    - Input/output tube diameter: outer 9mm, inner 6mm
    - Install size: 100*45*62mm

    These looks very much like caravan pumps. The shaft, is it ceramic or stainless steel.
    As far as I can remember, those caravan pumps got a brass / copper shaft. That is slightly exposed.

    On these I think it's stainless steel. I can confirm.

    no my guess is all plastic with a rubber diaphragm. i will assume the shaft is behind the plastics and will never be in touch with tank water.

    maybe just confirm like you say
