Peristaltic pumps with flow rates up to 17 gpm, pressure to 30 psi

March 27, 2007

Watson-Marlow Bredel announces the 720 Series peristaltic pump, which allows for production speed and flow control for high-capacity throughput. The 720 Series is designed for accurate metering and dosing of corrosive, abrasive and sensitive fluids, and is ideal for the contamination-free transfer of acids, paints, oils, inks, dyes or waste slurries found in industrial, chemical, and applications in the pulp and paper, printing, and food processing markets. Offering a smaller footprint than other industrial pumps with similar flow rates, the 720 Series provides low shear and non-contacting pumping with minimal downtime. The 720 Series includes single channel flows up to 8.8 GPM and 17.6 GPM through two individual tubes, as well as a choice of analog or digital control. Available in a robust NEMA 4X wash-down case, the pumps feature LoadSure tube elements for easy one minute maintenance. The 720 family of peristaltic pumps comes with the now-standard Watson-Marlow Bredel five-year warranty, the longest of any peristaltic pump manufacturer, according to Watson-Marlow. Every Watson-Marlow Bredel peristaltic pump is an inherent metering pump with repeatability at 99.5 percent. Many models include integral digital drives and displays in washdown enclosures. These self-priming 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 these pumps are reversible for back flushing lines. They can also run dry indefinitely without damage and provide up to a 30 foot suction lift.
