AWWA CEO David LaFrance thanks water professionals nationwide for keeping water safe for drinking
Dec. 16, 2014, marked the 40th anniversary of the Safe Drinking Water Act (SDWA), which today includes regulations for more than 90 contaminants. American Water Works Assn. (AWWA) CEO David LaFrance issued the following statement to mark the occasion.
BlueFlex-A-Prene heavy-duty pump tube, available exclusively for Flex-Pro and Proseries-M peristaltic metering pumps, has been carefully engineered and designed for optimum performance and pressure capability. Offering long tube life, precise flow rate and high chemical resistance, the tube reduces pump maintenance and related costs. The dual-molded tube withstands high pressures, and retrofits onto all Flex-Flo and Proseries-M peristaltic metering pumps currently in the field.
Flexflo peristaltic metering pumps are suited for smaller-scale applications with maximum outputs of 124 gpd and working pressures reaching 100 psi. The A-100N Series is compatible with a range of chemicals, featuring three tube material options: Norprene, Tygothane and FKM. It cannot vapor lock or loose prime, and has a tube failure detection system. It is designed to be compatible with the Micro-Flo flow verification sensor, with select digital models accepting 4-20 mA, 0-10 Vdc inputs for eternal speed control.
The Boxer 15000 line of peristaltic pumps includes three to six self-priming roller pumps that do not require lubrication and are offered with a choice of four inside tube diameters. They can achieve rotational speeds up to 780 rpm, which allows users to configure them to meet the requirements of a wide range of applications. The pumps also feature a “clip-on” pump head design and an anti-tamper locking screw.
More compact and with lower feed capability than the Flex-Pro A3 and A4 units, the A2 peristaltic metering pump is suited for smaller-capacity municipal and industrial water and wastewater treatment applications. Features include self-priming, a one-button prime mode, a degassing design that eliminates gas and air accumulation in the pump head, and a maximum feed of 33.3 gal per hour.
Benefits of the Flex-Pro A4 include: outputs to 171 gph, 1000:1 turndown ratio and continuous feed, output pressure ratings to 125 psi/8.6 Bar, automated PPM dosing, operator-friendly digital touchpad with menu-driven software, no-maintenance brushless variable speed motor, patented tube failure detection system and heavy-duty single-piece rotor. LCD displays motor speed, input signal values and service and alarm status.
New designs offer higher flow rates and pressure capacities
