It has a latex hose, the rollers are plastic tubes over brass tubes, and the motor&gearing comes from a copier device.

Not a great water flow, peristaltic pumps have low flow but not a problem here, I need just 40 seconds to dive using the pump, not bad; the main advantage of these pumps is that they seal wile not running; in my first design I used a geared pump but it leaked when stopped, taking more and more water after a while.
