What Walrus Pump Co. does

Walrus Pump Co. (大井泵浦工業股份有限公司) is a Taiwanese manufacturer of centrifugal and multistage pumps founded in 1967 and headquartered in New Taipei City. The company became the first Taiwan water pump manufacturer to list publicly when it debuted on the Taipei Exchange under stock code 6982 in December 2024. Its product portfolio spans centrifugal and multistage pumps for residential, industrial, and increasingly data center cooling applications, with named series including WQDC_B (intelligent ultra-quiet liquid cooling pumps), HS_B (multi-stage centrifugal), TPMK_P (immersible), and TPRK (industrial water pumps). The company has expanded into higher-margin smart and IoT-enabled offerings through its WAIC Smart Network Constant Pressure Pump Control System, an IoT Cloud Intelligent Pump Monitoring System, antimicrobial electronic control pumps, and in-house IE3/IE4 high-efficiency motors. A proprietary WALRUS FIT customized pump integration service allows the company to co-engineer solutions with OEM customers.

The company serves nine industries including construction, manufacturing, agriculture, and data centers, with an explicitly named anchor customer in Delta Electronics (台達電) for AI server cooling applications. Distribution covers Taiwan plus international operations in Vietnam, Thailand, Malaysia, Indonesia, China, Japan, Italy, Germany, and Poland. Manufacturing is anchored by the newly completed Kaohsiung Global Plant, providing capacity for approximately 600,000 pump units annually. Revenue mechanics combine branded product sales, OEM supply, and aftermarket service through a Taiwan-wide service center network, with the second-generation leadership reporting revenue doubling over a four-year transition. The company holds 100+ patents including industry-first antibacterial pump technology and maintains 7+ international certifications.

Forward strategy is anchored by repositioning toward AI server liquid cooling, evidenced by the 2025 Computex debut and the WQDC_B Series launch. Capital deployment has accelerated, with a NT$1.072 billion syndicated loan in April 2023 funding the Kaohsiung plant and a subsequent NT$12 billion syndicated facility (oversubscribed by 75%) closed in December 2025 to support further expansion. The combination of public listing, scaled manufacturing, international distribution, and an explicit pivot into AI infrastructure cooling positions the company as a mid-market industrial beneficiary of regional data center buildouts, though its AI capability is limited to IoT monitoring and its competitive differentiation rests primarily on accumulated patents, certifications, and brand rather than proprietary AI/ML technology.
