Peristaltic pump specialists introduce high performance, long life tubing for harsh chemical applications

New from peristaltic pump specialists Watson-Marlow Pumps Group is a high performance, long life tubing which is ideally suited 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 new tubing suitable for a range of aggressive chemicals such as concentrated acids like Nitric and Sulphuric as well as aromatic hydrocarbons like Toluene and Xylene.

At continuous pressures of 4 bar, consistent flow rates are 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 greater than 50 times longer life than conventional non-reinforced extruded Viton or Fluorel tubes.

Thanks to its expanded PTFE reinforcement, the new tubing also offers superior burst resistance to protect against aggressive fluids release to the environment.

Applicable to 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 will also benefit from this new innovation.

Style 400 tubing is currently available with internal diameters ranging from 1.6 up to 12.7mm, with wall thickness from 1.6 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 like 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, Watson-Marlow adds value to all pumping processes through significantly reduced maintenance, repair and calibration.

About us

Watson-Marlow Fluid Technology Group (WMFTG) peristaltic tube and hose pumps meet requirements including: value for money; low cost of ownership; reliability and ease of maintenance to the food and beverage, chemical, pharmaceutical, mining and many other industries.

We demonstrate how pumps deliver significant process efficiencies over the lifetime of the equipment. Whether performing flavouring addition in food processing, chemical metering in water treatment or mineral recovery, we have a solution which can cut pump downtime and reduce costs through higher accuracy metering and transfer. WMFTG has dedicated application engineers available to help customers make the right pump and tubing choice from a range providing microlitres per minute to 80 cubic metres per hour flow rates.

The only part of the pump to come into contact with the product is the tube or hose. This means there are no seals or valves that can wear or fail. Replacing the tube or hose can be performed quickly and safely. Peristaltic pump benefits include:

Total fluid containment with no seals No ancillaries Handle viscous and abrasive slurries and sludge Self-priming capability Dry running without damage to the pump In addition to their range of positive displacement pumps, Watson-Marlow Fluid Technology Group has added PTFE-lined chemical and industrial hoses to their range. Aflex hoses are reinforced to withstand the most severe conditions and use.
