Nikuni Co., Ltd. Company Overview
Only Nikuni demands such high machining precision for pumps.
Nikuni Co., Ltd. is a company (manufacturer) engaged in the development, production, and sales of pumps. In particular, we focus on the development, production, and sales of products centered around vortex turbine pumps, as well as the development, production, and sales of devices that improve the environment within factories by incorporating pumps (such as coolant systems and filtration systems). Pumps are the heart of devices and equipment. As a precision machinery manufacturer, Nikuni has been producing high-precision, high-quality components for many years. Utilizing our machining technology, Nikuni produces pumps with precision that exceeds the norms of general pumps (such as perpendicularity, parallelism, concentricity, and runout), resulting in pumps that pursue high precision and high quality. To prevent issues, we conduct a full inspection of all pumps before shipment, ensuring that only those that meet Nikuni's quality standards are shipped. Nikuni manufactures and sells products so that everyone involved with pumps can use them with confidence.
