Watson-Marlow”s Bredel SPX peristaltic pump is designed for challenging environmental applications. The pump handles a variety of harsh materials, including abrasive sludge. Advanced hose technology enables the pump to handle grit-filled sludge dependably for a long period of time. The pump is an inherent metering pump with repeatability at 99.5 percent. Many models include integral digital drives with PROFIBUS or SCADA control in NEMA 4X washdown enclosures. These self-priming pumps accommodate flowrates 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 the pumps are reversible for back-flushing lines. They can also run dry indefinitely without damage and provide up to a 30 feet of suction lift.
