Have purchased 6 of these pumps for industrial use in pumping small amounts of liquids.Would like to be able to purchase the pump tube separately. No option listed.

I use this pump to 3D print gels, it works well with the Arduino micro-controller.The only issue is the tube, it's short and the holder doesn't lock the tube in place

The tubing that comes with this motor wears out and starts to rip over time. It is very difficult to buy replacement tubing for this pump.Also, I'm trying to control to build a motor controller for the motor but there is no information online about the stepper motor. The marking says 2.5ohm>3V 1.3A. If there is a datasheet or more info on the motor that would be very helpful. At minimum I need to know to know if 1.3A is the average RMS value or the peak of sine. I will consider changing my review if the information becomes available.

I got this to control the location of a bubble in a liquid-filled tube. I started with a cheap DC motor powered pump but couldn't reliably "park" the bubble at the location, where the stepper can do that when told to do a certain number of steps from a driver (not included). The top of the pump where the tube goes is made of a strong plastic. It's easy to open and replace the tube. It just feels solid and the project is working now.
