Manufacturing Excellent Corrosion-Resistant Chemical Pumps with Ariron (high-silicon cast iron)

We manufacture and sell various types of pumps, including submersible pumps and submersible sand pumps for highly concentrated sludge.  Our chemical pumps, one of our main products, utilize Ariron (high-silicon cast iron) for higher sulfate- and saline-resistance. We also use Oleumon (acid-resistant pearlitic cast iron) , which has excellent acid resistance, in line with Ariron  for our pearlite pumps.

Other presentation

[Company strength]
Our chemical pumps are utilized at sulfuric acid plants , refineries, and other facilities in the chemical industry.  Our products have the world's top corrosion resistance against sulfuric acid, and are used by many Japanese major companies. Our product lineup includes standard items  as well as those with particular specifications.

[Business description]
We manufacture and sell chemical pumps, sand pumps, and aeration pumps .  We design and manufacture the pumps to order.  We provide pumps most suited to individual customer needs based our long accumulated know-how.  We will strive to supply quality products while developing new items.

Manufacture of pumps

[Strength of products/technologies]
Ariron (high-silicon cast iron), which is used in our chemical pumps, is highly resistant to sulfuric acid and saline.  It has, in particular, excellent acid resistance against sulfuric acid, in any degree of concentration (except oleum) and at any temperature.  Ariron has a high degree of hardness and wear/abrasion resistance,  and displays high corrosion resistance against drug solutions that contain slurry components.  Oleumon (acid-resistant pearlitic cast iron) is an acid-resistant material, which can be used for concentrated sulfuric acid and oleum.

Our chemical pumps are known for their durability, and rarely break.  Some pumps have been used for over 40 years with only consumable supplies (such as impellers and casings) replaced during that time.  

Our aeration and fountain pumps have unique mechanisms and exert maximum aeration intensity with minimum power (patented products). 

[Representative's message]
Since our foundation in 1955, we have held a leading position in the submersible sand pump industry in Japan.  Our products are well known in the chemical pump industry, especially the “Ariron” and “Oleumon” products.  
In the future, we strive to further improve the performance of our products in collaboration with public institutions and universities, and also to organize our development systems for the better.  We have a record of delivering our products abroad, and are planning to further expand into overseas markets mainly in India.

[Company structure for market development/overseas expansion]
We have staff members in charge of foreign transactions in our Sales Department, who handle all inquiries from overseas firms.  Our technical staff in the Design Department will respond to customer requests for consultation to help to solve their issues and problems.  We will consider making our homepage more global oriented for overseas clients.
