For Peristalic Pumps and Pinch Valves

GORE™ STA-PURE® high resilience pump tubing helps critical fluid handling processes run more cost-effectively. It delivers superior protection against bursting and product contamination – over a much longer time compared to conventional tubes. It maintains stable flow rates over time, handles high pressures, and high mechanical stress and virtually eliminates spallation. Using GORE™ STA-PURE® tubing means fewer changeouts and higher-purity fluid handling, so you can transfer media with utmost security and confidence.

Flexible and highly durable GORE™ STA-PURE® tubing performs exceedingly well in the most sensitive and sanitary production environments. Its unmatched purity significantly increases process consistency and product integrity, making it an excellent choice for pharmaceutical and biopharmaceutical applications.

The unique composite construction of GORE™ STA-PURE® tubing provides superior burst resistance compared to non-reinforced silicone rubber and thermoplastic elastomer tubing. With burst strength approaching 360psi (24 atm), the tubing can operate at elevated pressures for transfer, filtration, purification and in-line sterilization operations.

Spallation debris collected onto a microporous filter membrane after recirculating water for 48 hours through thermoplastic elastomer tubing (left) and GORE™ STA-PURE® tubing (right). The thermoplastic elastomer tube produces particles of rubber, inorganic filler, and plasticizer.

Virtually Eliminates Spallation

The exceptional toughness of the composite structure of GORE™ STA-PURE® tubing provides superior resistance to cracking and abrasion, virtually eliminating spallation. This means the risks of filter plugging and product contamination are significantly reduced without sacrificing tube life. Moreover, process streams stay cleaner, thereby reducing downstream filtration requirements. The end result: increased efficiency and throughput, along with reduced downtime.

Smooth Bore Reduces Contamination

The interior of GORE™ STA-PURE® tubing is significantly smoother than thermoplastic elastomer tubing. During pumping, thermoplastic elastomer tubing generates particulates that are expelled into the process stream. The RMS surface roughness is substantially increased, whereas GORE™ STA-PURE® tubing shows only a slight change in surface characteristics.
