| New 620 Series peristaltic pumps for industrial applications  Watson-Marlow Bredel has launched its 620 Series peristaltic pump, combining power and control. The 620 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 chemical, pulp and paper, printing, food processing and many other industrial applications. The 620 Series pumps can reliably deliver 50% more flow than the previous model; 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. The flagship pump in this series, the 620Du features manual control via a unique 16-key alpha-numeric keypad, as well as automatic control 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. write your comments about the article :: © 2005 Construction News :: home page |
