Hi there,
My name is Bogdan and I'm from Romania.
I'm a mechanical engineer specialized in the industrial robotic field, 3D designer and modeler.
I could make the model of your pump, but of course the price will be other than the bid.
About the model, I will need you to tell me what type of pump you need (eccentric poms, which are volumetric pumps could be with piston or diaphragm)
Another issue is the displacement and input parameters (rpm, eccentricity, viscosity of the fluid, inlet/outlet diameter, etc).
In this way, I invite you to open a msg channel here, and we'll discuss all the details of your project.
Regards
Bogdan
