What Walchem Corporation does
Walchem Corporation, operating as a brand and division of Iwaki America Inc., designs and manufactures online analytical instruments, electronic metering pumps, and sensors for water treatment applications. The product portfolio is organized around three integrated technology pillars: water treatment controllers (Intuition-9 with up to 24 inputs and 12 outputs, Intuition-6, and W100W); chemical injection metering pumps (IX Series with ±1% accuracy and 1000:1 turndown, E-Series family including EWN/EZ/EHE/EWP, LK/LKN large-capacity, EH-HV high-viscosity, and HRP OEM); and sensors including Pyxis fluorometers, WDS differential pH/ORP electrodes, disinfection sensors, conductivity probes, copper/nickel sensors, LPR corrosion sensors, turbidity and dissolved oxygen sensors. The Walchem Fluent cloud platform overlays the hardware with IoT connectivity, remote monitoring, alarm notification, and data visualization, transforming installed controllers into connected assets accessible via mobile and web interfaces.
The company goes to market exclusively through a network of master distributors maintaining local inventory of pumps, controllers, and spare parts with technical support capability, serving commercial/industrial cooling, boiler water treatment, metal finishing and PCB, municipal potable water, industrial wastewater, food and beverage, oil and gas, swimming pool/spa, agricultural fertigation, rural water, and reverse osmosis customers across North America, Latin America, Europe, the Middle East, Africa, Australia/New Zealand, and Asia. Pricing is not publicly disclosed; customers are directed to local master distributors. The company is privately held under Iwaki America Inc., a U.S. subsidiary of Japan's Iwaki Co., Ltd. (founded 1956, producing over 600,000 pump units annually across 25+ global centers), sharing headquarters and manufacturing facilities at 5 Boynton Road in Holliston, Massachusetts. Revenue recognition is primarily through hardware sales of controllers, pumps, and sensors, with Walchem Fluent representing a subscription/recurring component layered on top of the distributor channel. ISO 9001 certified, the company has been in operation for nearly 50 years (founded 1976) under leadership including President and CEO John Miersma.
