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.
