The Verderflex Reinforced Hose
The successful use of hose pumps in a number of situations led Verder to develop a hose with an enhanced construction. Hoses in peristaltic pumps generally fail due to fatigue of the reinforcement layer. Verder hoses are specifically designed and manufactured to maximise fatigue resistance, resulting in an extremely long hose service life.
Verderflex Hose Specification
- 12 standard hose sizes from 5mm (3/16”) to 125mm (5”)
- All hoses are designed to maximize hose life by increasing the the hoses’ fatigue strength
- Standard VF Hoses are available in Natural Rubber (NR), Nitrile Buna Rubber (NBR), Food Grade NBR (NBRF), EPDM and Hypalon® (CSM)
- Hoses have colour coded identification tapes bonded into the outer surface during manufacture to clearly identify material type.
A pump’s flow rate is determined by the hose’s internal diameter and the pump’s rotor speed. The recovery (restitution) of the hose is determined primarily by the design of the re-enforcing layers. These re-enforcing layers provide maximum resistance to repeated compression and relaxation, thereby ensuring maximum hose life. This restitution also produces a suction side vacuum and this provides the hose pump with a very powerful dry priming mechanism, allowing high viscosity liquids to be pumped.
