What Sakuragawa Pump MFG. Co., LTD does

Sakuragawa Pump MFG. Co., Ltd. is a Japanese manufacturer of submersible pumps and related fluid management equipment, founded in 1953 as Japan's first submersible pump producer and incorporated in 1955. The company designs, manufactures, and sells submersible electric pumps (0.4 kW to 185 kW across U, UEX, UOY, HS, UCF, NHS, DSN, DS, UE, J, G, H, and other series), gasoline/diesel engine pumps, submersible agitators and water mixers, automated cleaning machines (Brush Pit), squeeze pumps for viscous fluids, sprinkler trucks, and accessories such as float switches and pump testers. Core technology centers on vortex impeller design and durability-focused materials (high-chromium cast iron), with proprietary auto-pump features including capacitive sensor level detection and variable timer control.

The business operates as a direct-sales enterprise with 16 regional sales offices across Japan (Hokkaido to Okinawa) backed by 40+ authorized service shops, and an international distribution network covering East/Southeast Asia, the Middle East, Oceania, Africa, and the Americas. Revenue is generated primarily through hardware sales to construction/civil engineering companies (primary segment), municipal water authorities, agricultural and aquaculture operations, mining and dredging contractors, steel mills, and power plants. Pricing is not publicly disclosed and is handled through direct inquiry. The Fukui factory holds ISO 9001 (2000) and ISO 14001 (2007) certifications.

The company is a privately held subsidiary of AKTIO Group, Japan's largest rental company, having joined the group in April 2015. It is led by President Fumikazu Mizutani and operates with approximately 121 employees across domestic sales, manufacturing, and an overseas business division. Capital stands at JPY 58,750,000 as of December 2012. Three new product launches occurred in 2025 (Squeeze Pump, Sprinkler Truck, Passing Pump), indicating an active product surface expansion cycle alongside the company's 70th anniversary (2023) and proprietary NETIS registrations for public works procurement access.
