A pump is a device that imparts positional or kinetic energy to a liquid to transport or circulate it to a higher elevation.

As such, they are used everywhere from domestic applications such as wells and agricultural pumps to industrial plants (power generation, oil refineries, boilers, etc.).

Demand for pumps

According to Grand View Research, demand for industrial pumps in the U.S. is expected to increase by an average of 4.9% per year between 2022 and 2030.

Demand for pumps is expected to increase steadily, as there is room for pumps to be deployed in all sectors, including water, wastewater and chemical, oil and gas, and power generation.

The global industrial pumps market size was valued at USD 61.63 billion in 2021 and is expected to expand at a compound annual growth rate (CAGR) of 4.9% from 2022 to 2030. The rising adoption of these products in various industries, including water and wastewater, chemical, oil and gas, and power generation, is expected to have a positive impact on the market growth.

Let's look at Nikkiso's sales and net income margin.

Net sales(Consolidated)165780158542167759180000
Net income6813656022116500
[Millions of yen]

In FY2022, the gain from the sale of a subsidiary is expected to be added to profits, and the projected net income has jumped compared to the past four years.

Next, let's look at sales ratios and operating income ratios by segment.

Sales ratioOperating profit ratio
Industrial Division56.9%4.5%
Medical Division43.1%4.2%


Industrial Division: Leading manufacturer of precision pumps for chemical applications. Strong in special pumps (pumps for severe conditions such as high pressure, no leakage, and cryogenic temperatures).

Medical Division : Sells dialysis machines, consumables, and artificial kidneys. The company has a domestic market share of over 50% for dialysis machines.

Leveraging synergies with industrial pumps, we have strengths in the medical dialysis field.

Torishima Pump Mfg. Co., Ltd

Let's look at Torishima sales and net profit margin.

Net sales(Consolidated)48154471265078752240
Net income218354333533626
[Millions of yen]

Highest profits were recorded in FY2022/3 and are expected to continue in FY2023/3.

Next, let's look at sales ratios and operating income ratios by segment.

SegmentSales ratio
High-tech pumps42.8%
New energy, environment1.6%


High-tech pumps : Large pumps (engineering pumps) for power plants, desalination plants, water supply and sewage facilities, irrigation facilities, etc. and eco-pumps (small standard pumps) for general industry

Project : EPC (engineering, procurement, and construction) projects for entire pumping facilities at water, sewage, irrigation, and drainage pumping stations

Service : Replacement of existing pumps and pump equipment, maintenance inspections, parts replacement, etc.

New energy, environment : Design, construction, and maintenance for the introduction of wind power and small-scale hydroelectric power generation. Environmental equipment (vacuum sewage collection systems for agricultural community drainage)

Among the four segments, the high-tech pump segment performed particularly well, +92.7% YoY. This was due to special demand for agricultural irrigation pumps for Egypt.

Next, the new energy and environment segment performed well, up 46.5% YoY. In response to the trend toward decarbonization and carbon neutrality, we participated in Japan's first demonstration project of 20% ammonia co-firing power generation promoted by JERA Corporation.

Major Shareholders


Takuma, a major environmental plant manufacturer, has become a major shareholder. This is believed to be because the headquarters of Torishima Seisakusho and Takuma's headquarters are located close to each other and pumps will be needed for the construction of the waste treatment plant.


Let's take a look at Tsurumi sales and net profit margin.

Net sales(Consolidated)43461456044532551214
Net income4013395241564817
[Millions of yen]

There is a general trend of increased sales and profit.

Although sales ratios and profit ratios for each product business were not disclosed on the website, the overview of each domestic and overseas division was disclosed and is shown below.


Domestic Division : In the construction equipment market, sales of environmentally friendly electrode-type submersible pumps and high-pressure cleaners to the rental industry were strong. In the equipment market, orders from the public sector for projects related to infrastructure development, including measures against heavy rainfall, expanded, but demand from the tool factory equipment market remained flat.

Oversea Division : Active demand continued in the construction and mining markets, including the North American market. In the North American market, despite concerns about sluggish demand and reluctance to buy due to rapidly rising inflation and the Fed's interest rate hike, the mining and construction markets remained active and orders remained strong. 


Tsurumi Manufacturing is strong in submersible pumps (for civil engineering, construction, flood control, and water purification facilities) and has the largest market share in Japan (approximately 30%).

Major shareholder

10th Denyo Co., LTD.

DENYO, a major manufacturer of engine generators and welding equipment, is a major shareholder. The Tsujimoto family, the family of the company's president, is also on the list.


Let's look at Iwaki's sales and net profit margin.

Net sales(Consolidated)29171286362816232439
Net income2163212220912396
[Millions of yen]

Generally, there is a trend of increased sales and profit.

Next, let's look at sales ratios and operating income ratios by segment.

Sales ratio
Magnet pumps33%
Metering pumps17%
Air-driven pumps13%
Rotary positive displacement pumps7%
Air pumps5%

The strength lies in chemical pumps for transferring chemical solutions. Some of the liquids handled by chemical pumps are hazardous (e.g., sulfuric acid, which is harmful to the human body), and therefore require a very high level of safety to prevent leakage. The company's chemical pumps can be subdivided into the following categories


Magnet pumps: Combine corrosion resistance to chemicals with leak-proof safety.

Metering pumps: Always pump a constant amount of liquid and have excellent reproducibility of discharge volume.

Air-driven pumps: For semiconductor and liquid crystal markets

Rotary positive displacement pump: Capable of pumping special solutions (viscous liquids, slurry liquids).

Air pumps: Unlike the above four pumps that handle liquids, air pumps supply and intake air.

Annual income and average age of employees

Average incomeAverage ageThe number of employees(Non-consolidated)
EBARA757 million yen43.9years old4266 people
NIKKISO603 million yen42.3years old2011 people
TORISHIMA576 million yen38.3years old953 people
TSURUMi595 million yen41.0years old867 people
IWAKI656 million yen42.2years old795 people

The number of employees increases in the order of companies with the highest non-consolidated sales, indicating that sales per employee are roughly the same for all five companies.

However, the annual income of employees does not necessarily match the size of the company, with Iwaki's average annual income of 6.56 million yen coming in second to EBARA's 7.57 million yen.

Torishima Seisakusho has the lowest average annual salary among the five companies, and also has the lowest average age, indicating a large percentage of younger employees who tend to be paid less.


We have summarized the differences among three of the five major pump manufacturers (EBARA, Nikkiso, Torishima, Tsurumi, and Iwaki). The strengths of each company can be summarized as follows.


EBARA : Semiconductor manufacturing equipment (electronics segment)

Nikkiso : Medical field (dialysis equipment)

Torishima Manufacturing: Seawater desalination plants and irrigation facilities for overseas markets

Tsurumi Manufacturing: Submersible pumps for civil engineering and construction

Iwaki: Chemical pumps for transferring chemical solutions
