Watson-Marlow Bredel Introduces Its Newly Redesigned 520 U/R Pump

Watson-Marlow Bredel, the leading manufacturer of peristaltic pumps, showcased its redesigned 520 U/R peristaltic pump at INTERPHEX 2004 on March 16-18, 2004 in New York City. The 520 U/R pump provides increased power, control and flexibility. The pump's highly accurate metering and dosing performance makes it ideal for biopharmaceutical and process applications.

With an inherently sanitary design, the 520 U/R's streamlined case is smooth and sweeping with no puddling, bug traps or vertical splits. The only maintenance required of the 520 U/R is changing the tubing, which allows the fluid to remain completely contained eliminating any possibility of contamination.

Additionally, the 520 U/R offers a new pumphead design allowing for a higher range of flow rates, from 0.004ml/min. to 3.5 liters/min, and a wider turndown ratio. The large swept volume of the pumphead provides greater volumetric displacement per revolution, resulting in longer tube life and gentle handling of shear-sensitive fluids.

Equipped with MemoDose technology and a user-friendly interface, the 520 U/R allows for precise control while metering and dosing. For applications that demand remote analog operation or a contact closure, the sophistication of the controls combined with the simplicity of the design makes the 520 U/R the perfect pump for all your hygienic applications.

Every Watson-Marlow Bredel peristaltic pump is an inherent metering pump with repeatability at 99.5%. Many models include integral digital drives and displays in washdown enclosures. The full line of Watson-Marlow Bredel pumps accommodate flow rates from 0.1 microliter to 350 gpm, and are extremely durable, withstanding pressures up to 232 psi. There are no internal universal joints, valves, dead corners, or glands to impede flow, and all pumps are reversible for back flushing lines. They can also run dry indefinitely without damage and provide up to a 30-foot suction lift.
