Style 400 Datasheet - .PDF file.

Watson-Marlow Pumps Group has announced a long-life tubing suitable for harsh chemical applications.

The Gore high-resilience tubing: Style 400 is an expanded PTFE multi-layer tubing featuring high-performance Viton filler that is able to maintain a stable flow rate for thousands of hours while pumping aggressive chemicals.

This construction makes this tubing suitable for a range of aggressive chemicals such as concentrated acids such as nitric and sulphuric as well as aromatic hydrocarbons such as toluene and xylene.

At continuous pressures of 4 bar, consistent flow rates are said to be achieved throughout the lifetime of Style 400 tubing.

While chemicals will attack most other types of tubing, the secret behind the resilience of Style 400 is Viton GF-600S, a peroxide-cured fluoroelastomer based on Dupont advanced polymer architecture.

Performance testing shows that Style 400 tubing offers longer life than conventional non-reinforced extruded Viton or Fluorel tubes, according to Watson-Marlow.

With its expanded PTFE reinforcement, the tubing also offers burst resistance to protect against aggressive fluids being released to the environment.

The tubing is suitable for a host of applications including hydrocarbons pumping in the nuclear industry, nitric acid in dairies, toluene pumping in automotive screw lock application, solvent-based inks, hydrocarbon-based polymer dosing and a number of other sectors using chemicals.

Style 400 tubing is currently available with internal diameters ranging from 1.6mm up to 12.7mm, with wall thickness from 1.6mm up to 4.8mm to provide reliable metering of aggressive chemicals and increased process consistency.

The introduction of the durable and dependable Style 400 tubing brings now makes the peristaltic pump the natural choice for aggressive chemicals.

Whereas conventional pumps such as progressive cavity or diaphragm types suffer attack when pumping chemicals such as nitric or sulphuric acid, or aromatic hydrocarbons such as toluene, the principle of peristaltic pump operation dictates that the fluid only touches the bore of the tube.

With no valves or seals to block or corrode and just the simple maintenance of occasionally changing a tubing element, pumping processes can achieve reduced maintenance, repair and calibration.
