(Japan), operating as one of more than 25 global manufacturing and support centers for the Iwaki Group. Founded in 1960 and headquartered in Holliston, MA, the company designs, manufactures, and sells chemical handling pumps and related fluid control equipment under four divisions: Iwaki Pumps (magnetic drive centrifugal, metering, and high purity pumps), Walchem (analytical instruments and electronic metering pumps for water treatment), Iwaki Air (air-operated double diaphragm pumps), and Iwaki Aquatic (aquaculture research systems). Its core technologies include sealless magnetic drive pumps with dry-running capability, valveless ceramic piston metering pumps achieving ±0.5% dosing precision over 40,000+ hours, and lined magnetic drive process pumps rated to 300°F with up to 10% solids handling. Capacity spans 24–1,320 GPM across magnetic drive models and 3.2–856 GPH across metering models.

The company operates a distributor-led go-to-market through a network of Master Distributors in the U.S. and internationally, with direct field sales for OEM partnerships that have spanned more than 50 years. Pricing is quote-based and not publicly disclosed. Revenue is generated through hardware sales of pumps, OEM custom pump development, and Walchem analytical/instrumentation products, serving end markets including chemical manufacturing, water treatment, semiconductor fabrication, plating and metal finishing, mining, bio-fuels, desalination, petroleum refineries, and data center cooling. The company maintains manufacturing and R&D in Holliston, MA, and is actively extending commercial coverage into Latin America (Mexico, Caribbean, and Andean regions) and newer verticals such as battery manufacturing and data center thermal management.
