KOSAKA Products in Our Life

We manufacture marine pumps designed to meet the demanding requirements of ships, including compact design, durability, and ease of maintenance.
Our pumps are used in a wide range of applications, including the transfer of fuel, lubricating oil, fresh water, and seawater, as well as the recovery of spilled oil.

We provide hydraulically driven pumps and hydraulic systems designed for chemical tankers that transport hazardous chemicals.
As the only manufacturer of these systems in Japan, we help ensure the safe operation of chemical tankers every day.

We manufacture high-pressure pumps that inject backfill grout into gaps between concrete tunnel walls and the surrounding soil or rock during tunnel construction.
By helping prevent deterioration and collapse of tunnel walls, our pumps contribute to the long-term durability of tunnels.

Oil refining involves a wide variety of liquids, including those at temperatures above 200°C, as well as corrosive and toxic liquids.
We provide pumps that meet international standards for the safe transfer of these liquids.

We manufacture robust, long-lasting pumps designed to support hydroelectric power generation over many years of operation.
Our pumps supply oil to hydraulic systems that regulate the amount of power generated by controlling water flow.

For over 70 years, we have provided lubricating oil pumps for bearings essential to the operation of turbines, generators, boilers, and other equipment at power plants.
Our pumps also transfer various types of fuel oil used in power plants.

We provide measuring instruments that check the roundness of bearings used in wind turbines, helping ensure they are manufactured to the precise dimensions specified in their designs.

We provide measuring instruments capable of nanometer-scale measurements required in the manufacture of semiconductors, functional films, and other products. Despite using a stylus-based measurement method, our instruments can precisely measure film thickness and the internal profiles of through electrodes without damaging the measured surface.

We manufacture measuring instruments essential for the production of automotive parts such as engine components, as well as for vehicle body measurement.
Our measuring instruments combine high measurement accuracy with excellent operability, helping support automobile manufacturing.

We provide large-scale instruments for measuring step height in flat-panel displays used in smartphones and Flat Panel Displays.
We hold the world’s leading market share in this field and flexibly accommodate the different specifications and production lines of individual manufacturers.

We provide equipment that automatically bonds LED chips with high positioning accuracy.
Our equipment enables high-precision, high-speed bonding.

We manufacture equipment for bundling sausage packages and applying tape to the sides of bento packages.
