History of "Monozukuri" (Manufacturing)

Submersible Pumps

1954

In 1953, a portable generator integrated with an engine and motor was developed, using an engine for a Pointer motorbike which was manufactured around this time. About the same time, our company received a proposal from a domestic manufacturer to "jointly produce a domestically made self-priming type engine pump of the U.S.," and our company started development of the engine unit that we were in charge of.

  • 1954 Completed First Pointer self-priming type pump

    Since the Fuse Plant (around this period) which was in charge of the development of the engine for the self-priming type pump had almost no experience in manufacturing engines for pumps, they started development with technical assistance from the Naruo Plant which was producing engines for motorcycles. After going through a trial and error for six months, the first "Pointer Shiner" was completed. They continued to improve the engine, and started mass production of the "Pointer" the following year.

  • "Self-priming type pump" captured top share

    After the mass production started, the sales volume increased due to aggressive sales activities and expansion of the sales distributors. We assigned engineers to the distributors to provide a repair service. In 1957, since the sales volume of the pumps increased so much that production could not meet the demand, we decided to internally manufacture the pump units which were outsourced, which resulted in the manufacturing of the entire system. Around this time, competitive products also started to be released one after another. In order to defeat the competitors, we developed 30 to 40 models in response to the various requests from users. This strategy helped our company capture the top share in the industry for the self-priming type pump field in 1963.

  • 1964 Technical collaboration with Swedish company for the manufacturing of electric submersible pumps

    We received an offer from the Swedish company who heard about the reputation of the self-priming type pumps regarding sales collaboration where they wanted to promote sales of their submersible pumps in Japan. However, since our company was a manufacturer, we concluded a technical collaboration agreement for the purpose of manufacturing their product in Japan, not only to perform sales activities. While performing sales of their products, we obtained technological support from them, and we also started development of modified their products in order to develop high performance products, taking advantage of the knowledge and technology gained with the self-priming type pump.

  • Changeover from self-priming type pump to a submersible pump

    The submersible pumps made overseas attracted attention in Japan, because the pump was equipped with an automatic connection unit which was not yet available with products made in Japan. Taking advantage of this opportunity, our company changed the field of focus from a self-priming type pump to a submersible pump for civil engineering and equipment, where a demand could be expected.

  • 1972 Developed submersible comminuting pump "CPC80"

    Developed the first submersible comminuting pump equipped with a chopping function based on the design of our company. We continued to develop submersible pumps according to the applications and delivery destinations, and submersible pumps with diameters of 200 to 500mm were made into a series in 1975. This series demonstrated excellent ability in sewage treatment plants and rainwater drainage pump stations, and gained a favorable reputation.

  • Expanding business from "submersible pumps" to "fluid."

    From the latter half of the 1970s, we offered a lineup of various products used in sewage treatment plants, in addition to submersible pumps. From 1978, the year the technical collaboration agreement was terminated with the Swidish company, we started exporting products overseas, including Taiwan, Malaysia and other countries. In 1992, after we overcame the hardships from the economic deterioration, etc., the Ono Plant was established in Ono City, Hyogo prefecture as a base for the "fluid" business, looking towards expansion of the market in the future. The plant responsible for the design, assembly and inspection of various products including the submersible pumps, has created a range of various products.

  • 1995 Developed lightweight submersible pump "NORUS"

    Started sales of a tough and lightweight submersible pump "NORUS" with rust protection for purification tanks.

  • From 2000 Developed high efficiency & high passage performance submersible pump "CNW" Series (2005)
    Developed high efficiency & high passage performance submersible pump and Non-clog Scroll submersible pump "CNWX" Series (2008)

    The "CNW" series was developed according to requests from the sales division. Adoption of a new non-clog impeller realized both high efficiency (energy saving) and high passage performance, and also passed performance tests of the Japan Institute of Wastewater Engineering and Technology (JIWET). Although the downturn in the business performance continued due to the reduction of budgets for wastewater facilities around this time, the "CNW" demonstrated its advantages as a differentiated product. The "CNWX" which evolved from the CNW series was developed three years later. As a result of realizing high energy savings while maintaining 100% pass through of solid matter, the sales grew favorably. The CNWX has now became our main product.

  • 2018 Developed submersible pump "e-NORUS" made of high-performance resin

    The adoption of the uniquely developed operation controller and electrode sensor, realized the industry's first automatic alternate and simultaneous operation with float-less pumps of the same type. Accordingly, it also realized space savings and weight savings.

In the future

We will develop submersible pumps which contribute to the achievement of the Sustainable Development Goals (SDGs) , which is to "6. Ensure availability and sustainable management of water and sanitation for all." The intention of ShinMaywa is to provide highly efficient and energy saving oriented products and after-sales service to the world that can only be provided by our company, which supports wastewater treatment infrastructures behind the scenes in cooperation with the sales, plants and service departments into the future.
