Kamoer KPHM400-SW3B25 400ml/min high Flow peristaltic Pump 12V dc Brushed Motor lab Liquid dosing Pump with BPT Tube

Haven't measured the flow but seams about right. Have been running at least once a day for 10 mins for the last few weeks without issue.

Pump flows 170ml/min at max using oil. Very ncie build quality

Uses to pump gear oil into differential, works great!

Works well

So far this has been great. Verified max flow rate was 460 ml/min using a graduated cylinder and plain water, connected to around 5' of 0.17" ID tubing, with no lift or pressure. A couple of things would make it better: it's not easy to change the squish tubing in the rollers. It's definitely designed to leave the tubing in there for periods of time. if you wanted to change out tubing for lab purity or whatever, you might pick another design. Also, mounting could be easier. would love to have a mounting template for the holes included in the box. Also the mounting points are neither through holes or threaded. Maybe you're supposed to use self-tapping screws for plastic? i dunno, I tapped them to be threaded for #6x32 threads, which seems like an unnecessary step. EDIT: after purchase I did notice there's a link on the product page to a PDF with a mounting template. So it does exist, just not in the packaging. https://m.media-amazon.com/images/I/A1at7U9PyNL.pdf

First try it leaked all over the place. Took the shell off and the tube was mangled and had a slice in it. Now I have to go get a piece of tubing if possible.
