TUBING TECHNOLOGY Select your tube Choosing the PERFECT tube for all of your applications Watson-Marlow is the only peristaltic pump manufacturer in the world to manufacture its own tubing, optimising our tubing tolerances and formulation to deliver the best process pump performance. In a peristaltic pump, the tubing largely dictates pump and system performance: Its restitution creates suction, its strength resists pressure, its flex resistance determines pumping life, its bore defines the flow rate, its wall thickness controls pumping efficiency and its purity protects your product from...

GORE STA-PURE PCS®hasaunique composite construction of silicone in a ePTFE lattice giving it superior burst resistance up to 7 bar (lOOpsi) and 18 times longer life than silicone tubing. It produces virtually no spalling, is USP Class VI approved and is classified as non-toxic. Working temperature range -20C to 80C. Opaque white. Autoclavable, SIP and CIP compatible. GORE STA-PURE PFL® is effectively pumpable PTFE - a high performance composite of ePTFE and a high-grade fluoroelastomer - offering extraordinary chemical resistance, long life and very high burst pressures. STA-PURE PFL is USP...
