Enhanced PU tubing for peristaltic pumps

Spetec GmbH has enhanced its PU-Longlife solvent-resistant tubing, part of its product portfolio for peristaltic pumps. The updated material is now significantly more supple, allowing operation at much lower compression levels. This reduces wear on both the pump and, in particular, the pump heads. Made from a highly durable thermoplastic polyether polyurethane (PU), the tubing offers excellent resistance to hydrolysis and an extended service life.

When used in peristaltic pumps, the tubing achieves an expected service life of 500 continuous operating hours (tested with distilled water at 33 RPM). Actual performance may vary depending on the solvent, tubing diameter, compression, and other influencing factors.

PU-Longlife tubing is particularly suitable for solvents such as alcohols, benzene, diesel, and kerosene. These improvements open up a broader range of applications compared to the previous version of the tubing.

The physical properties are summarised in the table:

The tubing is sensitive to moisture and light and should always be stored in its original packaging in a cool, dry place, protected from light.

A solvent resistance table is available on request, and tubing samples can be provided for testing with specific media.

Further details on usage and legal requirements is available in the Technical Data Sheet.
