Aflex Bioflex Ultra - Smooth Bore PTFE Hose
The key feature of Bioflex PTFE hose is the PTFE liner design, which comprises integral rib sections which support the tube against kinking, vacuum and pressure, and highly compressed web sections which give a smoothbore inner surface and excellent flexibility.
Bioflex Ultra flexible hose with PTFE liner is the best product for fluid transfer in many industries. It can be used for chemically inert, clean Pharmaceutical hoses, as a corrosion-resistant suction discharge Chemical Hose, as a fully compatible Food and Drinks Hose, and to transfer paints and other process fluids. Bioflex Ultra is used worldwide in biopharma, chemical manufacturing, research facilities, food, and drink processing plants. It has an unrivaled record for reliability, performance, long service life, and high quality.
Bioflex Ultra in Comparison with Convoluted PTFE Hose
- Hygienic Cleanability - much better, due to no internal convolutions
- Flow Rates - more than 2 x higher
- Pressure Ratings - more than 1.5 x higher
- Self Draining - excellent self draining with PTFE lined fittings
- Non-Whistling - no whistling noise with gasses
Bioflex Ultra in Comparison with Conventional Smoothbore FEP, PFA or PTFE Lined Rubber Hose
- No Adhesives - no toxic adhesives used in the Bioflex Ultra construction, eliminating the possibilities of Process Fluid contamination in service
- Flexibility - much better flexibility
- Internal Shape Control - no distortions in bore when flexed
Bioflex Ultra in Comparison with Silicone Rubber Hose
- Hygienic Cleanability - much better, due to the non-stick PTFE Liner
- Chemical Resistance - considerably improved, particularly to strong oxidising acids and bases
- Temperature & Pressure Ratings - much higher temperature and pressure capability
- Steam Resistance - permanently resistant to steam sterilising (unlike silicone hose, which has a limited life)
In practice, flow rates will vary with hose flexing, fluid viscosity, end fitting design and other parameters, but Bioflex Ultra hose flow rates are always around 2 times better than convoluted PTFE hose, when comparing hose assemblies with PTFE lined (non bore-restricted) end fittings.
Bioflex Ultra Hose - Flow Rate Calculation
If it is required to determine the flow rate of a particular hose assembly, or if it is required to determine the pressure required to generate a certain flow rate, then this can sometimes be approximately calculated by the Bioflex Ultra supplier.
It should be noted that calculations can only be made for fluids with a viscosity equal to water, and for hose assemblies with PTFE lined end fittings (no bore restrictions at the ends of the hose).
