Teikoku Electric Works

What Teikoku Electric Works does

Teikoku Electric Works, now operating as Teikoku Corporation after a 2025 corporate rebranding, is a Japanese industrial equipment manufacturer headquartered in Tatsuno, Japan, founded in 1939 and listed on the Tokyo Stock Exchange under ticker 6333. The company operates with 1,001–5,000 employees and is the world's leading supplier of canned motor pumps, where the motor and rotor are hermetically sealed inside a single canned housing with the pumped fluid, eliminating shaft seals and preventing leakage of hazardous, toxic, or valuable fluids.

The company's product portfolio spans four core lines: canned motor pumps (its flagship category), metering pumps for precise chemical dosing, canned motor agitators for mixing sealed-process fluids, and electric oil pumps. The new IE Series brings ISO2858 dimensional compliance, broadening the install base into European-standard process plants. Teikoku's electric oil pumps are deployed across the JR Shinkansen high-speed rail fleet, representing 100% penetration in that mission-critical application.

Teikoku generates revenue through direct industrial equipment sales, project/specification sales to engineering, procurement, and construction (EPC) contractors, and aftermarket service in chemicals, petrochemicals, oil and gas, power generation, semiconductors, and rail. Strategic positioning in 2025–2026 has emphasized international trade shows (Gastech for LNG/hydrogen, SEA JAPAN for maritime) and a corporate identity refresh designed to elevate the brand beyond its "electric works" heritage, targeting new verticals tied to the energy transition.
