Hakusan Kiko, in addition to custom-made production of coolant units and chip conveyors for chip discharge, also offers the Pump Back System for medium to large-scale plants where multiple machine tools are in operation.

Batch processing of chips and coolant liquid!
The Pump Back System for Labor and Space Savings

The Pump Back System is a centralized processing system that treats chips and coolant (cutting fluids) discharged from multiple machining centers (machine tools) together using a large filtration unit. By collecting chips and cutting fluids from each machine, it enables transport through overhead piping. The cleaned coolant fluid then travels back through the overhead piping to the machining centers.

Hakusan Kiko has obtained a patent for its circulation processing system and has been offering this solution in Japan for over 20 years. As the Hakusan Group, we have achieved approximately 300 installations to date.
