Watson-Marlow Bredel , a leading manufacturer of peristaltic pumps has launched its 620 Series line for industrial processing applications.
The 620 Series peristaltic pumps combine power and control with flow rates up to 4.8 gpm and pressure up to 60 psi.
The 620 Series pumps are the next generation of peristaltic pumps, offering market-leading flow rates at pumphead speeds that don't compromise tube life.
The 620 Series peristaltic pumps are designed for accurate metering and dosing of corrosive, abrasive and sensitive fluids, making them ideal for contamination-free transfer of acids, paints, oils, inks, dyes or waste slurries found in chemical, pulp and paper, printing and food processing among many industrial applications.
With their extended performance, 620 Series peristaltic pumps can reliably deliver 50% more flow than the previous model. This new series provides excellent performance with a control ratio of 2650:1.
With no valves or seals to clog, the 620 Series peristaltic pumps require minimal maintenance, resulting in reduced downtime and providing a cost-effective alternative to other pump technologies.
The 620Du is the flagship pump in the series and features manual control via a unique 16-key alpha-numeric keypad as well as automatic control (analogue and RS485 communication) for remote operation and 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.
Watson-Marlow Bredel peristaltic pumps are inherent metering pumps 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 microlitre 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-feet suction lift.
