Pre-engineered pump systems from Walchem, Iwaki America Inc. provide chemical feed solutions for a range of applications and are available in four configurations, from economical, basic systems to full-featured redundant backup systems.
The core of every system is a rugged, chemical-resistant pump stand molded from UV-stabilized, linear low-density polyethylene. Components added to the stand to create the various systems include calibration columns, back-pressure/anti-siphon valves, pressure-relief valves, pulsation dampeners, gauges, ball valves and Y strainers. An auto-fill option provides the plumbing and valves to enable the metering pump to fill the calibration column for applications when flooded suction is not available. A floor-mount design is standard, but the compact pump systems also are wall mountable and offer large-capacity spill containment with a drain designed into each stand.
Typical applications are cooling tower/boiler water treatment, pH adjustment, chlorination, sanitary cleaning, drinking water treatment (fluoride/pH), closed-loop systems and scrubber replenishment.
