Watson-Marlow Bredel Launches 620 Series Peristaltic Pumps

Wilmington, MA Watson-Marlow Bredel, the leading manufacturer of peristaltic pumps, has launched its
620 Series peristaltic pump, combining power and control. The next generation of peristaltic pumps, the 620 Series introduces market-leading flow rates at pumphead speeds that don't compromise tube life. The 620 Series reliably handles harsh chemicals in the water and wastewater treatment industry, including sodium hypochlorite, ferric chloride, sodium bisulfite, aluminum, fluoride, carbon and lime slurries, polymers, aqueous ammonia, potassium permanganate and caustic slurries.
With its extended performance, 620 Series pumps can reliably deliver 50% more flow; a single 620RE pumphead is capable of 4.8 gpm and pressures up to 60 psi. This new Series provides unrivaled 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, providing a cost-effective alternative to other pump technologies.
The flagship pump in this series, the 620Du features manual control via a unique 16-key alpha-numeric keypad, as well as automatic control (analog and RS485 communication) for remote operation and SCADA process integration.
The 620 Series offers an exclusive, innovative PIN-secure process protection feature that provides two levels of PIN protection. For general biotech applications such as purification, the speed range can be capped to prevent accidental damage to delicate filters. In sensitive fermentation processes, keypad functionality can be disabled to avoid any inadvertent changes to pump settings. The keypad can also be disabled in remote installations to prevent tampering.
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 0.1 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' suction lift.
