Hi there, This is Bogdan from Romania. I'm a mechanical engineer, specialized in the industrial robotics, 3D modeler and designer. I have over 15 years work experience, designing, prototyping and launching different devices/systems across multiple industries. I could help with your project, but I really need more details/info about. 1 - the peristaltic pumps are positive displacement type, where to one revolution of the rotor will pump a determined quantity of liquid. on the other hand, while the battery discharges the motor will not be able to keep the pumping parameters... 2 - another question is about the variation of the liquid (do you need fixed amounts or you need variable amount to be pumped everytime?) 3 - in any case, instead of the peristaltic i would recommend you to use a syringe pump (btw - the price shown is an estimate and could be adjusted accordingly with the further discussions...) For any other questions, you may open a chat room here and we'll discuss about the details. Regards Bogdan

i, at oltron technology, have done the project where I have made a motor attached to keyboard and other devices unlike in a petrol pump, where using the keyboard, one can press any number and depending upon the number pressed, one get the desired quantity of the liquid. it was battery operated and portable, so that anyone can use at any place. i can deliver in budget mentioned ans in 5 days time. for further discussion, you can contact me and if you need, i will send you the report of that project so that you can be sure that i can do the same.
