    Greetings.

    Happy new year.

    Im just wondering what kind of pump do you use for paste sles, im tired of ussing cups and jars, and im ussing arround 400lb of sles/day, im ussing 2″ diaphagram pump at 80psi for liquid soap and shampoo but they doesnt work for sles.

    You’d better make a dilute SLES working solution yourself.
    Working with pastes is too time consuming and difficult.

    Not for nothing many suppliers sell 26-29% SLES instead of the paste.

    Diluting 60/70% SLES paste with 2x its water weight yields a water-thin solution.

    If the working solution will be left standing for too long, you may wish to add preservatives. Although SLES ain’t too prone to feed bacterial growth.

    Thanks You @Gunther for your answer, it is about 30% more expensive buying 28% sles, it takes 2.5 more volumen to  tove shipped My country, i can’t afford that.

    There must be a suitable pump, i’m buying sles from LG household and they are selling a Lot 70% drums, so i’m wonfering what kind of pump are ussing the industries, worm, gear, pistón pumps.

    a rotary lobe pump is best for non-Newtonian fluids
    also, the engineering firm Bran & Luebbe supply mixing systems specifically designed for diluting SLES, you might want to look into one of them
