Intended for filtration, fermentation and dispensing applications, meeting full quality testing standards, including USP Class VI, ISO 10993 and USDA requirements
Watson-Marlow Bredel introduces its 620/520 family of peristaltic pumps, designed for the accurate metering, dosing and transferring of corrosive or sensitive fluids in sanitary environments.
The 620/520 pumps are said to be ideal for filtration, fermentation and dispensing applications, meeting full quality testing standards, including USP Class VI, ISO 10993 and USDA requirements.
The next generation of peristaltic pumps, the 620 series introduces market-leading flow rates at pumphead speeds that don't compromise tube life, says the company.
With their extended performance, 620 series pumps can reliably deliver 50% more flow than previous model; a single 620RE pumphead is capable of 18l/min and pressures up to 4.1bar.
This new series claims unrivalled performance with a control ratio of 2650:1.
With no valves or seals to clog, the 620 series pumps require minimal maintenance, resulting in reduced downtime, and providing a cost-effective alternative to other pump technologies.
For ultimate processing flexibility and increased flow rates, Watson-Marlow Bredel's 520 series pumps provide low shear, contamination-free pumping and predictable pump service intervals extending validation periods.
The 520's high-powered, brushless DC motor gives it controllability from 0.1rpm to 220rpm with speed accuracy to 0.1%.
It provides precision dosing and metering, resulting in exceptional batch consistency with a 875,000:1 flow range.
The new 520 pumphead accepts eight different tubing materials and sizes up to 9.6mm for flow rates ranging from 4microlitres/min up to 3.5 litres/min at 2bar.
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.
These self-priming pumps accommodate flow rates from 0.1microlitre to 1.3m3 per minute, and are extremely durable, withstanding pressures up to 16bar.
There are no internal universal joints, valves, dead corners, or glands to impede flow, and these pumps are reversible for back flushing lines.
They can also run dry indefinitely without damage.
