STOUT PERISTALTIC PUMP FABRICATED FROM scratch

The peristaltic pump is possibly many well understood for its ability to pump fluids without the pump system coming into get in touch with with the working fluid. This is essential for food-safe applications and other circumstances where a pump might contaminate the fluid. [Maciej Nowak] has developed a excellent example of such a pump, crafted out of aluminium from scratch.

The build video covers the machining process in detail, showing exactly how the aluminium body was fabricated on the lathe before installing bearings and a silicone hose. The pump shaft was then fabricated, together with a set of brass rollers to press along the tube, producing the pumping action. The rollers were also lubricated in purchase to decrease friction on the tubing. Powering the pump is a little DC motor, sending drive through a little toothed belt, providing the completed build rather an industrial look.

We’re utilized to seeing lots of 3D-printed pumps about the place. This build, while it needs a fully-equipped device shop, is much tougher than anything plastic, and you might quickly utilize it to break a window in an emergency too, an obscure function nonetheless requested by some discerning pump customers.

[Maciej] shows off the build by pumping some eco-friendly liquid, noting the peristaltic style needs no priming which makes operation much easier. It’s also bidirectional, and can be run extremely slowly if required.

Overall, it’s a build that shows off the benefits of working in metal in addition to the excellent features of the peristaltic pump design. video after the break.
