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
