What ASSOMA INC. does

ASSOMA INC. (legal name 協磁股份有限公司) is a Taiwan-based, privately held industrial pump manufacturer founded in 1978 and headquartered in Taoyuan City. The company designs, manufactures, and sells magnetic drive (seal-less) centrifugal pumps and canned motor pumps primarily for handling corrosive, hazardous, and high-purity chemicals. Its product portfolio spans four categories: plastic chemical pumps (AVF-C, AVF-X, AVF, AM, AMX series), metal-housed lined pumps (AMXI ETFE-lined, AME PFA-lined, AMA ISO ETFE-lined), pump monitors and dry-run protectors (DRP-D, AVF-M), and precision chemical filters (AMF series). Core technology eliminates mechanical seals via magnetic coupling, achieving zero-leak operation, and selected AVF-C and AVF-X models are the world's first plastic canned motor pumps to exceed EU MEI > 0.7 efficiency thresholds per Regulation 547/2012 with IE5 high-efficiency motors. ASSOMA also operates Taiwan's first TAF ISO 17025 accredited pump performance testing laboratory, providing independently certified performance reports under ISO 9906.

The company serves four primary end-markets: PCB manufacturing (precision chemical transfer, etching, plating), the broader chemical industry (corrosive acid/alkali transfer), environmental engineering (wastewater treatment, gas scrubbing, chemical dosing), and the energy sector. The business model is build-to-order: customers submit application specifications, ASSOMA's technical sales team performs chemical compatibility analysis and NPSHa calculations, and customized configurations are manufactured to order with automatic hydraulic testing before delivery. Revenue is generated through direct sales, an authorized global distributor network spanning 13+ countries, a wholly-owned China subsidiary (Shanghai Xie Cheng Chemical Machinery Co., Ltd. with branches across eastern, southern, central, northern, and southwestern China), a joint venture in Japan (ASSOMA JAPAN with TOHKEMY Corporation), and OEM/ODM white-label partnerships (notably with EBARA Corporation Japan since 2007 and Anderson Pump and Process in the US under the T-Mag brand since 2011). Professional services revenue is derived from customized engineering support, lifetime maintenance, and the ILAC-accredited testing laboratory open to all pump brands.

ASSOMA holds 20+ international patents across USA, UK, Japan, Taiwan, China, Germany, Italy, Thailand, and Korea, and has won 11 consecutive D&B Elite SME Awards (2014-2025) alongside Taiwan Excellence Awards (2017, 2022), a Taiwan Chemical Industry Association Excellence Award, and the 18th Rising Star Award from the Taiwan Ministry of Economic Affairs. The company holds ISO 9001, ISO 14001, ISO 45001, ISO 17025, and QC 080000 certifications. Founder ownership is implied, with no disclosed external investors or public listing.
