In most cases , we tend look at pump material of construction when come to handling of corrosive pumping media and this usually cause no problem if the materials are compatible to the media to be pumped
However the construction material of drive components like geared unit or motor is often ignored .If the pump media are store in open tank , evaporation takes place rendering
the working area to be full of acidic fumes .These fumes will then corrode the gear nox or motor
which usually in cast iron construction . You almost never come across motor with SS body ,right ?
Solution
a) get the work area well ventilated
b) coating of the Gear unit and motor with proper coating
c) choose a motor that is Aluminum body , plastic fan cover and plastic
terminal box
These will surely extend the life of it and lower the maintenance
A customer in Gemas has been paying good attention in this issue and I am glad
to hear one of the pump has been able to last
