A pump in which the fluid never touches metal parts can solve many design problems. 💡
A hose pump is a positive displacement pump in which a rotating rotor with rollers or feet cyclically compresses a flexible hose, pushing the fluid from the suction side to the discharge side.
This creates a continuous vacuum on the suction side, and the fluid is transported exclusively inside the hose, without contact with metal parts. ✅
The hose is a wearable component, available in a wide range of materials - including those certified for food contact, paving the way for applications in food, cosmetics and pharmaceuticals. 🫧
For lower pressures, rollers with solid lubricant are used; at higher pressures, the correct compression ratio of the hose is key, which directly affects the possible discharge pressure.
