Aflex Hose - Watson-Marlow Fluid Technology Solutions products

Bioflex Ultra GP is the ‘General Purpose’ grade, for use in all applications where fluids or gases are being conveyed which do not generate a risk of static charge development (see “AS”).

Bioflex Ultra AS is an essential requirement in applications where there is the risk of an electrostatic charge build-up on the inside surface of the PTFE tube which may then discharge through the tube wall. Media passing through which create such a risk are fluids which have a Conductance of less than 10^-8S/m (Siemens per Metre), or 10⁴ pS/m such as fuels, solvents, freons, some WFI (ultra-pure “Water for Injection”) and non-polar organics which are being transferred at a medium to high flow velocity.

Polypropylene braided hose is often preferred to SS in applications involving frequent handling and movement of the hose, and where temperatures are within the range -30˚C and +100˚C (-22˚F to +212˚F). PB braid is lighter in weight, and any broken strands will not cut the operator’s hands. In addition, PB braid is not prone to “chloride stress corrosion”, and has generally good chemical resistance.

For the most rugged applications where the hose may be subjected to rough treatment and severe external abrasion. Also for hygienic applications, where the external smoothness and cleanability of the hose is of prime importance.

Bioflex Ultra BK grade is designed to provide an alternative Rubber Cover which has the additional properties of making the hose Fireproof, and also making the rubber cover Anti-static.

As for RC hose, but where the hose may be required to withstand temperatures from -73˚C, -100˚F up to +204˚C, +400˚F. SI grade hose is semi-transparent, allowing visual monitoring of the braid.

In applications where excessive flexing of the hose at the end fitting occurs, it is sometimes necessary to ‘stiffen’ the hose in this area, to prevent kinking.

To protect the hose against external abrasion and mechanical damage. For use in applications where maximum external protection is required with minimum extra hose weight. Particularly useful with PB hose, where a rubber cover is not an option.

For medium duty applications where the hose requires some protection against abrasion when dragged over the ground, but where a full rubber cover would be too heavy and cumbersome. Also for PB braided hose, which cannot be Rubber Covered.
