General-purpose pumps are mechanical products for a very extensive range of applications as devices for running various fluids such as water in avariety of industrial plants and civil engineering works. These widely distributed products for a broad range of applications have a large influence on the environment. Therefore we started to develop our pump recycling business from these general-purpose pumps as the first step in constructing products that can be recycled. Used pumps that are no longer needed are shipped from our fully equipped inverse factory after cleaning and recycling some parts, and carry out performance tests so that they can be used reliably by new customers. We aim to expand the recycling business to cover all over Japan based on our experience.
