Peristaltic pump for transferring olive oil

The Rotho peristaltic pump respects the integrity of the product until it leaves the pump. It is designed to avoid contamination of the oil by external agents, emulsifying and oxidation, allowing the olive mill to obtain more fragrant oils with a more balanced flavour and fuller colour.
