    Pumping chocolate sauce

    Hello everyone! I'm in the process of designing a new piece of equipment. I have the PLC and HMI programs already written. I have all my prox sensors on hand, and I have a rough idea of what the machine even looks like.. lol! What i don't have is a way to push room temperature chocolate and caramel sauce through a .250 SS tube around 20psi. I've looked at peristaltic pumps and diaphragm and tested several types. None will push the sauce though. Chocolate sauce is around 20k cps. Just to make things more difficult I would like a small pump, think drive through Espresso stand and how little room there is. I'm also limited on power. I prefer a pump that runs on 12 or 24 vdc but no more that 120vac with a current draw of 10 amps or less....

    This question is best pursued by contacting pump suppliers (we don't allow commercial posts here BTW). Figure out the viscosity of the fluid you're moving and reach out to the various pump suppliers in the world.
    Tell me and I forget. Teach me and I remember. Involve me and I learn.
