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.
