Ready-to-Run, Skid-Mounted Metering Pump Systems

Peristaltic pump builder Watson-Marlow Bredel now offers complete chemical skidmounted metering systems designed for chemical feed applications at water/ wastewater treatment facilities and industrial applications. These skid systems come with a calibration column and all piping needed for an easy-to-operate and easy-to-maintain metering pump system. The systems require minimal ancillary equipment—no back-pressure regulators, de-gassing valves, strainers, pulsation dampeners or additional piping, and according to the manufacturer, require less maintenance than alternative systems— just a one-minute tube change—and deliver an accuracy of +/-0.5%. The company says all of its peristaltic pumps are inherent metering pumps with repeatability at 99.5%. Many models include integral digital drives with Profibus or SCADA control in NEMA 4X washdown enclosures. The 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-ft suction lift.
